Having come and gone more than once over the past 150 years, hydrofoils are all the rage again and here to stay this time. The latest technology has overcome many of the shortfalls of older systems, but are foiling superyachts feasible?<img src="https://photo-assets.superyachttimes.com/photo/308780/image/large-abca08ac22ef3c76d219eca23c4a28dd.jpg" data-gid="gid://syiq/Photo/308780">Over the past two decades foiling has taken off, literally and figuratively. It started with the innovative boards designed by surfers, followed by the specialist one-man classes like the foiling International Moths. Then came the high-performance sailing projects such as the 60-foot foiling trimaran l’Hydroptère, which broke the 50-knot barrier in 2008 and hinted at an exciting if highly specialised future for foils. But the idea of foils on mainstream leisure boats and superyachts has always seemed somewhat remote.<img src="https://photo-assets.superyachttimes.com/photo/308784/image/large-93508982c0f2307aa183db514c6f8972.jpg" data-gid="gid://syiq/Photo/308784">More recently, the advent of electric propulsion in tandem with the rising interest in foils, thanks largely to their adoption by the <a data-gid="gid://syiq/Company/6878" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="SailGP (Company)">SailGP</a> and <a data-gid="gid://syiq/Event/190" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="America's Cup 2024 - 37th America's Cup Barcelona">America’s Cup</a> sail racing programmes, has again brought foiling to the fore because they resolve a very basic problem. For boats with electric propulsion, or experimental hydrogen fuel cells in the case of the new <a data-gid="gid://syiq/Event/190" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="America's Cup 2024 - 37th America's Cup Barcelona">America’s Cup</a> chase boats, hydrodynamic drag means that displacement hulls and (to a lesser extent) planing boats struggle to attain a practical range for the given power-carrying capacity between charging. It is here that foils offer a clear advantage: if you can get your boat to emerge from the water and ‘fly’, you don’t need to worry so much about drag and the given power you are carrying in your battery banks can take you that much further. <img src="https://photo-assets.superyachttimes.com/photo/255101/image/large-3c47262ba3d15266b43994009e44c595.png" data-gid="gid://syiq/Photo/255101">“Our strategy is go faster to go further,” says Michael Jost, former Chief Strategy Officer at the VW Group who oversaw the start of the Group’s long-term transition away from fossil fuels. It’s a game plan Jost is employing with his new venture, eD-TEC, which has developed the all-electric eD-QDrive system. SilentYachts is coupling the system with a foiling 28-foot HYSUCAT multihull design to create a 40-knot electric boat that the catamaran builder claims still offers a range of 70 nautical miles.Electric avenue&nbsp;Across the spectrum, the combination of foils and electric drive systems is taking hold. Small boat builders such as Swedish brand <a data-gid="gid://syiq/Company/5799" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Candela Speed Boat (Company)">Candela</a>, <a data-gid="gid://syiq/Company/5737" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Enata Marine (Company)">Enata</a> in the Middle East, <a data-gid="gid://syiq/Company/6284" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Navier (Company)">Navier</a> in the US and Eldorado in the Netherlands, among others, are already building foiling leisure, passenger, water taxi and workboat vessels. The water toy world is alive with eFoil boards and the personal watercraft segment is also getting wise with projects such as the Valo Hyperfoil that adds retractable active foils to electric-drive jet skis.However, things get a little more complicated when it comes to larger craft. The advent of high-speed hydrofoil passenger vessels in the latter part of the 20th century was followed by a marked decline as the limitations of larger foilers became apparent – notably, the need for flat hulls with limited viability in bigger seas, and the potential for striking waterborne objects that could damage or destroy foils made from materials that were not as advanced as they are now.<img src="https://photo-assets.superyachttimes.com/photo/308788/image/large-eb9a1f3f86b23adca1520c7e78078250.jpg" data-gid="gid://syiq/Photo/308788">Considerable progress has been made in sailing with vessels such as the F50 used on the <a data-gid="gid://syiq/Company/6878" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="SailGP (Company)">SailGP</a> circuit, the new AC40 and AC75 yachts for the <a data-gid="gid://syiq/Event/190" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="America's Cup 2024 - 37th America's Cup Barcelona">America’s Cup</a>, along with the Ultime trimarans and IMOCA 60s. All these boats show how consistent 40-to-50-knot-plus performance is possible through the extreme application of surface-piercing foil technologies. Indeed, there has even been a crossover with sailing yacht projects like <a data-gid="gid://syiq/Company/6478" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="King Marine S.A. (Company)">King Marine</a>’s FlyingNikka&nbsp;mini maxi and sailing superyacht <a data-gid="gid://syiq/Yacht/10936" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Raven34.0m (111'7&quot;)Baltic Yachts2023">Raven 111</a> from <a data-gid="gid://syiq/Company/327" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Baltic Yachts (Company)">Baltic Yachts</a> that use foils to mitigate some of the displacement rather than making the hull fully fly. At the same time, however, they have also highlighted some of the limits to mainstream adoption.The foil wing tips are one. Even when the arms are folded under the hull for docking, they project more than two metres either side the yacht. Then there is the complex (and expensive) structural engineering needed to build and mount the arms into the topsides. Finally, there’s the sailing aspect, which requires precision and experience when powered up in foil-assisted flight.Practical limits&nbsp;For Seattle-based naval architect Paul Bieker, one of the world’s foremost experts on hydrofoiling, sailing foilers will always be limited by these constraints: “I would be surprised if fully foiling configurations find a significant place in mainstream, non-professional sailing yachts,” he says. “They require a lot of sailing skill and focus, high maintenance, expensive equipment, and they have a significant potential for personal injury.”&nbsp;Retractable foiling systems like the Dynamic Stability System (DSS) developed by Hugh Welbourn, Gordon Kay and Will Brooks, offer advantages such as improved righting moment, reduced heel and better motion in a seaway, plus more stability for big-boat, big-sea sailing. <img src="https://photo-assets.superyachttimes.com/photo/308786/image/large-d78769a2b71c292caceeab81b0112753.jpg" data-gid="gid://syiq/Photo/308786">“<a data-gid="gid://syiq/Yacht/10936" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Raven34.0m (111'7&quot;)Baltic Yachts2023">Raven</a> is not a yacht you could imagine relaxing in – it’s a balls-to-the-wall affair,” says Henry Hawkins, Executive Vice-President at <a data-gid="gid://syiq/Company/327" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Baltic Yachts (Company)">Baltic Yachts</a>. “But we used the DSS on the <a data-gid="gid://syiq/Company/327" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Baltic Yachts (Company)">Baltic</a> 142 Canova and it’s a completely different kettle of fish. There was a wish for a &nbsp;performance increase, but it wasn’t the driving factor behind the owner’s decision to install it.”The design demands of creating a full-flight vessel are, for the most part, incompatible with larger luxury yachts. Weight is a critical issue, for one, and while that can be overcome by adding larger foils, which in turn offer a greater aspect ratio and therefore greater lift, but there is an upper limit to the practical design of hydrofoils.“In general, the weight of a vessel scales with the length squared and the amount of lift that you can get off a foil scales with length squared – this reality means that there is a point where hydrofoiling gets more difficult with increased size,” says Bieker. “That said, the control of active hydrofoils tends to get easier with size because the actuators do not have to move as fast as they do in a smaller boats with smaller foils.”<img src="https://photo-assets.superyachttimes.com/photo/308860/image/large-a60ff05e451e2cee5403bcbd867c7901.jpg" data-gid="gid://syiq/Photo/308860">Bieker thinks there is more potential for moderate-sized foiling motor yachts: “The operating parameters for motor yachts are better defined and there is great potential for improving fuel consumption and comfort,” he says. “That said, they will still be significantly more expensive than non-foiling vessels.”Romain Ingouf is Technical Director at Artemis Technologies, a maritime engineering firm that emerged out of the Artemis Racing team that competed in the <a data-gid="gid://syiq/Event/190" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="America's Cup 2024 - 37th America's Cup Barcelona">America’s Cup</a>. The Belfast-based company has partnered with Condor Ferries to develop the 24-metre Artemis EF-24, a commuter ferry equipped with electric eFoiler propulsion able to carry 150 passengers at a top speed of 36 knots with a range of 95 nautical miles. Ingouf suggests that 24 metres in length overall with a displacement of around 75 tons is the sweet spot for a foiling monohull powerboat design.“You don’t want to have a boat that has foils sticking out at the sides because you need to get alongside docks and manoeuvre around marinas, and so forth,” he says. “You can certainly go bigger, to as much as 36 metres most likely, but then very rapidly you need a very beamy boat to have the aspect ratio on your foil so you are more efficient at creating lift without adding too much drag. Is foiling the solution to everything? Very likely not, although it’s fantastic in some applications.”<img src="https://photo-assets.superyachttimes.com/photo/308857/image/large-849e3ed467e7f08e313e6c73c4f635a4.jpg" data-gid="gid://syiq/Photo/308857">The future for foils?The future for foils beyond smaller vessels may be limited when it comes to full-flight solutions, but that doesn’t exclude potential for foils in large yacht design. Indeed, appendages that can improve efficiency and comfort – particularly when combined with stabilisation systems to offer multi-axis motion control – have been available for more than a decade. The Hull Vane, a fixed foil or wing designed and patented by <a data-gid="gid://syiq/Company/460" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Van Oossanen Naval Architects (Company)">Van Oossanen Naval Architects</a> that was first fitted on the 42.4-metre <a data-gid="gid://syiq/Company/54" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Heesen Yachts (Company)">Heesen</a> yacht <a data-gid="gid://syiq/Yacht/4639" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Ares42.4m (139'1&quot;)Heesen Yachts2014">Alive</a> in 2012, has proven itself on more than 65 yachts as well as commercial and military vessels.“The Hull Vane is derived from a device we developed for the French America’s Cup campaign in 2002,” says Perry van Oossanen, the studio’s Managing Director. “It’s not really intended to make a boat a foiling vessel as it’s designed for displacement hulls; we’ve taken a different approach by taking the vessel as it is and trying to enhance performance where we can.”&nbsp;The effect is less radical, but so is the technology involved. The location of the Hull Vane under the transom is important relative to the centre of gravity and works best if there’s a steep upcoming flow, which means quite steeply angled buttocks to the transom, but it can be retrofitted on any type of displacement hull.“It works well for a Froude number [the resistance of a partially submerged object moving through water] of 0.2 and upwards,” says van Oossanen. “For a 50-metre boat you’re there at five or six knots, and for an 80-metre boat you’re there at around 13 to 14 knots. We’ve installed it on a 100-metre patrol boat, but essentially the bigger the yacht the faster it needs to go to gain maximum benefit of the Hull Vane.”<img src="https://photo-assets.superyachttimes.com/photo/308778/image/large-e6090620180e08c2025c730977695724.jpg" data-gid="gid://syiq/Photo/308778">Hull Vane BV has also developed Foil-Assist, a partial foiling solution mounted amidships on fast planing vessels that applies the same concept to fast hulls and was first used two years ago on a Wajer runabout. It should be noted that both the Foil-Assist and Hull Vane increase not only efficiency but also onboard comfort – an important consideration for any yacht owner. &nbsp;“However, although applications for foils are definitely increasing, there are a lot of owners out there who are not really interested in the foiling stuff,” warns van Oossanen. “They want to have volume, space and luxury and they don’t necessarily want to cruise at 30 knots.”While that may be true, foiling technology is set to grow, particularly as the superyacht industry enters its own energy transition. Even if methanol in reformers for fuel cells or multi-fuel engines becomes the energy carrier of choice, its energy density is considerably lower for a given volume compared to conventional diesel. So while the fuel may be cleaner, yachts will need to burn less of it for a given volume of tankage to avoid losing too much practical range, while adding more tanks means taking volume away from guest areas. In this scenario, non-flight hybrid foiling solutions could find their niche in mainstream yacht production and there may be a place for more extreme solutions for owners who want a more engaged boating experience.&nbsp;“There is potential for hydrofoil-assisted, non-flying boats, but there is no substitute for flying,” says Bieker. “Once you feel the acceleration that occurs when that last bit of hull leaves the water it is hard to stomach partial foiling solutions.”<img src="https://photo-assets.superyachttimes.com/photo/285014/image/large-1afb80631a7886e71900e1011ca9ab77.jpg" data-gid="gid://syiq/Photo/285014">Getting over the humpWhen the <a data-gid="gid://syiq/Company/327" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Baltic Yachts (Company)">Baltic Yachts</a> 111 <a data-gid="gid://syiq/Yacht/10936" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Raven34.0m (111'7&quot;)Baltic Yachts2023">Raven</a> hit the water for sail trials in the summer of 2023, all eyes turned to this sleek, foil-assisted superyacht. As the team gradually edged the yacht towards its performance limits, the yacht started hitting consistent speeds in the high 20-knots range, and the sailing world was abuzz. However, this style of yacht will probably remain an outlier and while great for exhilarating performance on the water, it is not ideal for coastal cruising with the family. The leeward foil is designed to carry up to 60 per cent of the yacht’s displacement at speed, but the engineering that has gone into creating a structure capable of handling the extreme loads has been immense.“The fitting which is bolted to the hull-deck joint of the foil arm is one metre long and made of machined titanium, for example,” says Kenneth Nyfelt, Sales Director at <a data-gid="gid://syiq/Company/327" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Baltic Yachts (Company)">Baltic Yachts</a>. “The tolerances on all those fittings are incredible fine; you cannot allow any rattling or any vibration from it because then you are dead.”Even with Canova’s DSS, Henry Hawkins believes it will take time for most owners to gain confidence in the technology: “Look at how long it took us to get carbon rigging and canting keels onto boats; they’re still the unknown, and what people have taken from the racing scene is that the foils are always breaking,” he says. “So there’s a hump to get over, but I think there is a realisation that there is something to be offered by foiling technology, and it’s a question of how long it will take to find its way into the mainstream.”<img src="https://photo-assets.superyachttimes.com/photo/308861/image/large-11b3b0797fa572b289df3d06472924b7.png" data-gid="gid://syiq/Photo/308861">Tender trendsSmaller foiling boats and RIBs, whether using full-flight foils or foil-assist solutions, offer plenty of potential as standalone leisure boats, chase boats or tenders, particularly as alternative drive systems come on stream. Among many pioneers in this field is Gordon van Hardenbroek, an industrial designer and co-founder in 2015 of foiling boat company Edorado.“We started with a basic design premise of taking a planing hull, taking out the combustion engine and putting batteries in,” he says. “There weren’t many people doing it at the time, but we found as soon as you start going fast the range plummets. And I don’t believe that battery tech will improve enough to solve that problem. We realised that adding foils – in our case an active system made possible thanks to advances in sensors and computation – could double our range. Finally we realised that market demand was for retractable foils.”In addition to creating their own 8.35-metre 8S model, Edorado is also planning to release a pre-engineering platform that targets the superyacht sector. “The 8S is very much about flying,” he says. “It’s not about getting you from A to B, but rather the goal is the flying itself.”

<a data-gid="gid://syiq/Company/5438" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Akerboom Yacht Equipment (Company)">Akerboom Yacht Equipment</a>&nbsp;has earned a prominent position in the superyacht supply chain for its bespoke boarding equipment, platforms, cranes, watertight doors and integrated control systems. Yet the engineering philosophy behind its custom-designed solutions is based on a resolutely modular approach.When Mervyn van der Ploeg was appointed managing director of <a data-gid="gid://syiq/Company/5438" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Akerboom Yacht Equipment (Company)">Akerboom Yacht Equipment</a> in 2015, the company was going through a bad patch. It routinely redesigned everything from scratch for each new yacht project, leading to prototype-level inefficiencies and financial strain. A small but telling example is that it used to produce 32 different types of locking pins. Today, through a process of standardisation and modularisation, that number has been reduced to just two sizes.<img src="https://photo-assets.superyachttimes.com/photo/396743/image/large-c20dda6c39f046eea94eaa71057b9e2c.jpg" data-gid="gid://syiq/Photo/396743">“Previously, when designing a platform for a yacht, four different locking pins might have been specified, requiring multiple suppliers,” explains van der Ploeg. “Now, we buy 200 locking pins per year in two sizes from a single supplier at half the cost.”The process began by redesigning a prototype passerelle from scratch using a fully modular approach, which then became a template for other equipment. While remaining a supplier of custom equipment, modular components are now reused across <a data-gid="gid://syiq/Company/5438" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Akerboom Yacht Equipment (Company)">Akerboom</a>’s product range, reducing design complexity and streamlining production.“A key technical insight came from looking outside the yachting industry,” continues van der Ploeg. “For example, swivel joints originally designed for excavators have been incorporated into our gangways. These components are proven, industrial-grade and standardised, which means we can build highly reliable systems without reinventing core mechanisms.”In the ten years since van der Ploeg joined the company, turnover has more than doubled from €12 million to €25 million, driven by increased efficiency along with larger yachts and a rising demand for integrated equipment.<img src="https://photo-assets.superyachttimes.com/photo/396739/image/large-d48d0f06ceeb5a00cfda9bafe1c96878.jpg" data-gid="gid://syiq/Photo/396739">Make it modularThe spin-off from <a data-gid="gid://syiq/Company/5438" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Akerboom Yacht Equipment (Company)">Akerboom</a>’s modular way of thinking are innovations designed to maximise open space while eliminating visual clutter. Many of these solutions revolve around relocating drive systems into hinge lines and the platform structures themselves. In one recent project, a large side platform was initially conceived as two separate elements with a manually installed infill piece. While technically feasible, it was operationally awkward. Instead, by introducing an internal hinge drive already proven elsewhere, the entire system was re-engineered as a single monolithic platform. The infill was eliminated, deployment became faster, crew workload was reduced, and the geometry became cleaner.<img src="https://photo-assets.superyachttimes.com/photo/396744/image/large-4feaec6057dc57f70fe27a2f2a88296b.jpg" data-gid="gid://syiq/Photo/396744">The Sliding Stairs Access Hatch is another example.

Essentially, the staircases on each side of the pool form the hatch itself, with half of each staircase retracting into the deckhead like a gangway to provide access to the beach club.<img src="https://photo-assets.superyachttimes.com/photo/396742/image/large-bd76338bca2c0e5436acede35e416f93.jpg" data-gid="gid://syiq/Photo/396742">“This marked a next step in modular engineering for <a data-gid="gid://syiq/Company/5438" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Akerboom Yacht Equipment (Company)">Akerboom</a>,” says van der Ploeg. “Our approach not only accelerated the development process, but also showed how modularity enables flexible, cross-disciplinary solutions without compromising quality.”As both staircases form part of the watertight boundary of the vessel certified by Class, one of the main challenges was ensuring watertight integrity, given the angle at which the stair hatches are installed, as well as aligning the treads between the hatches and the fixed structures. In fact, sealing has become a central issue as stern structures grow more complex – folding, rotating and closing at compound angles. While inflatable seals are often the go-to solution and offer excellent theoretical performance, they also represent a single point of failure. <a data-gid="gid://syiq/Company/5438" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Akerboom Yacht Equipment (Company)">Akerboom</a> typically prefers D-profile rubber seals, which wear gradually, remain locally manageable, and allow temporary mitigation.<img src="https://photo-assets.superyachttimes.com/photo/396741/image/large-cf52ffb86158af5f4ac7a5922058d9b5.jpg" data-gid="gid://syiq/Photo/396741">“This approach is especially critical for Lloyd’s-certified watertight items such as split transom doors closing at different angles, where corners and junctions between curved surfaces become critical failure points,” van der Ploeg points out.Such solutions highlight how <a data-gid="gid://syiq/Company/5438" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Akerboom Yacht Equipment (Company)">Akerboom</a> has evolved beyond developing hardware to innovating the onboard experience, a strategy that has resulted in multiple patented solutions, from pop-up gangways embedded in the stern platform to protective cabrio covers engineered to fold, stack or nest completely out of sight when not in use. At the last edition of <a data-gid="gid://syiq/Company/4374" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Metstrade (Company)">Metstrade</a>, the company presented five interactive aft deck models through immersive 3D visualisations showcasing how engineering, design and user experience increasingly converge in the early phases of yacht development.<img src="https://photo-assets.superyachttimes.com/photo/396745/image/large-b406b1bef2a73b0811b05344a273be7e.jpg" data-gid="gid://syiq/Photo/396745">Under controlAnother defining feature of <a data-gid="gid://syiq/Company/5438" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Akerboom Yacht Equipment (Company)">Akerboom</a>’s approach is that its control systems and programming are all developed in-house. Precise timing between electronic commands, hydraulic oil flow and mechanical motion is critical, as are programmed delays that account for inertia and mass. Most systems employ frequency-driven power packs rather than simple on/off hydraulics, resulting in smoother movement, lower noise levels and the elimination of hydraulic ‘hammer’ effects. Automated operating cycles manage sequencing, speed and end-of-stroke deceleration automatically, reducing the risk of impact damage and operator error.

During the COVID period, <a data-gid="gid://syiq/Company/5438" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Akerboom Yacht Equipment (Company)">Akerboom</a> expanded its remote-support capabilities and identified a recurring issue: when faults occur, crews often cannot describe what happened beyond “pressing the button”. To address this, its latest systems incorporate data logging that records each operating cycle, sequence order, timing, load condition and fault event with precise timestamps.“When an issue arises, engineers can trace it back to the exact operating condition that caused it,” explains van der Ploeg. “While still being rolled out primarily on new-build projects, data logging represents a shift towards evidence-based rather than purely scheduled maintenance.”Across <a data-gid="gid://syiq/Company/5438" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Akerboom Yacht Equipment (Company)">Akerboom</a>’s predominantly hydraulic product range, failures rarely originate in the actuators themselves. Instead, the most vulnerable areas are where forces converge – locations where multiple loads are transferred into a single structural interface. Passerelles are a prime example:“Forces are transmitted through long, slender structures back to a limited number of mounting points,” explains van der Ploeg. “When additional functionality is introduced, such as lateral slewing rather than straight-line deployment, those forces increase substantially.”<img src="https://photo-assets.superyachttimes.com/photo/396750/image/large-74a75f9786460908e4bf98d749448420.png" data-gid="gid://syiq/Photo/396750">Bonding and bolt-inSome <a data-gid="gid://syiq/Company/5438" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Akerboom Yacht Equipment (Company)">Akerboom</a> passerelles now extend up to 16-metres in length, pushing the limits of lightweight structural engineering while maintaining stiffness, safety margins and regulatory compliance. Designing these interfaces requires careful attention to geometry, material thickness and fatigue behaviour.Marine-grade aluminium remains the primary structural material, selected for its high strength-to-weight ratio and corrosion resistance. Steel is used selectively in high-load interfaces where stiffness and wear resistance are critical. Carbon fibre has also been deployed strategically, particularly in the outermost sections of passerelles. Reducing mass at the extremity lowers bending moments throughout the structure, enabling greater reach without adding reinforcements.&nbsp;A more recent addition to <a data-gid="gid://syiq/Company/5438" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Akerboom Yacht Equipment (Company)">Akerboom</a>’s fabrication methodology is the introduction of structural adhesive bonding. In lightweight aluminium constructions, particularly passerelles, welding thin sections sometimes caused unacceptable deformation due to heat input. To address this, <a data-gid="gid://syiq/Company/5438" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Akerboom Yacht Equipment (Company)">Akerboom</a> now uses a hybrid method: components are positioned with bolts to prevent movement, while the structural adhesive provides the primary load-bearing bond. In this configuration, the bolts act purely as locators and the adhesive carries the load.Another key evolution is the move towards bolt-in housings for boarding equipment such as passerelles and swim ladders. Historically, these housings were built directly into the hull, placing installation and testing squarely on the shipyard’s critical path. This new approach uses self-contained housings that are assembled and factory-tested in-house, accepted by owners or representatives, and installed later as plug-and-play units.“Once delivered, the housing is bolted into place, hydraulics and electrics are connected, and functionality is assured – eliminating the risk of delays, rework and repainting,” says van der Ploeg.<img src="https://photo-assets.superyachttimes.com/photo/396752/image/large-1ea3884318d73cd6441f8d9cf8801f9c.jpg" data-gid="gid://syiq/Photo/396752">Breaking outSolely owned by <a data-gid="gid://syiq/Company/4951" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Koninklijke De Vries Scheepsbouw (Company)">Koninklijke De Vries,</a> until recently <a data-gid="gid://syiq/Company/5438" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Akerboom Yacht Equipment (Company)">Akerboom</a> worked exclusively within <a data-gid="gid://syiq/Company/29" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Feadship (Company)">Feadship</a>.

Standardising the bespoke: The engineering behind custom superyacht equipment

Akerboom Yacht Equipment explains how modular engineering is reshaping its custom superyacht boarding systems, platforms, cranes and control systems.

Project YB256 is a 45-metre steel and aluminium motor yacht under construction at <a data-gid="gid://syiq/Company/40" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Royal Hakvoort Shipyard (Company)">Royal Hakvoort Shipyard</a> in the Netherlands.

Wedged into a narrow strip of dockland between the old town centre and the water’s edge, space is as precious as the custom yachts it builds, but over the years the management has perfected a choreography of space and timing to ensure multiple projects can progress without tripping over one another.“<a data-gid="gid://syiq/Company/33" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Hoek Design Naval Architects B.V. (Company)">Hoek Design</a> is just a few kilometres down the road and we’ve often wanted to work with them, but the stars never aligned,” affirms Klaas Hakvoort, fourth generation director of the shipyard with his brother Albert Jr. “In this case, the client wanted Dutch pedigree, was happy with our pricing, and the complexity of the project was a perfect match for a custom builder like us.”<img src="https://photo-assets.superyachttimes.com/photo/396206/image/large-71da8891dd01ddb5eed6ecc0455c82e1.jpg" data-gid="gid://syiq/Photo/396206">Project YB256 was inspired by <a data-gid="gid://syiq/Yacht/6037" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Blue II55.99m (183'8&quot;)Turquoise Yachts2020">Blue II</a>, the 56-metre expedition vessel with classic lines by <a data-gid="gid://syiq/Company/33" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Hoek Design Naval Architects B.V.

(Company)">Hoek Design</a> partners Andre Hoek and Ruurt Meulemans translated the client’s admiration for the retro-influenced yacht into a more compact platform that would echo the same timeless elegance free of nostalgic mimicry, while embracing modern technology and efficiency. The owner’s exacting brief included full wheelchair accessibility, an elevator connecting all deck levels, and transatlantic capability.“The hull and superstructure were conceived to balance classic proportions with today’s efficient hydrodynamics,” says Ruurt Meulemans. “Computational fluid dynamics [CFD] analysis informed every curve, refining the bow shape and optimising volume distribution to reduce resistance as much as possible and improve wake flow to the twin propellers. The objective was a smooth, efficient ride across a transatlantic cruising envelope of close to 4,000 nautical miles – no small achievement for a vessel under 400 gross tons.“<img src="https://photo-assets.superyachttimes.com/photo/396218/image/large-f219694742e3fedf1f00ff2c0b5c4003.jpg" data-gid="gid://syiq/Photo/396218">Meeting these requirements called for some clever engineering based on robust, proven solutions. Finite element analysis (FEA) guided the placement of bulkheads, stringers, and the keel to ensure structural integrity under long passages without compromising interior volume. The challenge was compounded by hybrid-assisted propulsion comprising twin 1,000-hp MAN diesel engines paired with electric motors and supported by a lithium-ion battery bank.The system integrated by <a data-gid="gid://syiq/Company/3869" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Eekels Technology BV (Company)">Eekels Technology</a> allows for flexible operational modes. Electric mode provides a few hours of silent propulsion at low speed, ideal for manoeuvring in harbours or environmentally sensitive zones. In diesel mode the electric motors can function as shaft generators to reduce fuel burn on extended passages. The electric motors also add redundancy for additional peace of mind far from home. <a data-gid="gid://syiq/Company/40" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Royal Hakvoort Shipyard (Company)">Royal Hakvoort</a> had direct experience of the latter: during sea trials of 61-metre <a data-gid="gid://syiq/Yacht/8621" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Asia61.0m (200'2&quot;)Royal Hakvoort Shipyard2024">Asia</a>, an electrical fault caused an engine shutdown, but the gearbox-mounted e-motors allowed the crew to manoeuvre safely away from an offshore wind farm.<img src="https://photo-assets.superyachttimes.com/photo/396210/image/large-bfbd4613c1cb6d84c9fb37fa9b5d37a0.jpg" data-gid="gid://syiq/Photo/396210">The battle for spaceA signature feature of the yacht is the continuous ribbon of wraparound glazing on the main and bridge decks – 17 tonnes of it. The bulwarks are also glass and the hull windows incorporate a dot-fade pattern that blends with the white hull from a distance. Combined with the classic sheer line and bronze-metallic funnel, the green-tinted glass adds a touch of understated elegance that hints at an era that never quite existed – but should have. The wheelhouse windows are not full-height, but the aluminium surfaces beneath will be clad with glass and the same green reflective finish to create the visual effect of uninterrupted glass.&nbsp;Extensive glazing has a downside, however: heat. Solar load becomes a critical issue, especially for a yacht destined for hot climates. One option is to increase HVAC capacity, but a smarter one is to engineer better insulation. <a data-gid="gid://syiq/Company/40" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Royal Hakvoort Shipyard (Company)">Hakvoort</a> chose the latter. A two-year development programme with glass specialist Royal-Maritiem sought the ideal balance of solar control, privacy, clarity, structural strength, and colour uniformity. Each double-glazed laminated pane is filled with argon gas and coated with a low-emissivity metal film tuned to deliver the desired green tint. The result is a 50 precent reduction in heat transfer compared to conventional marine glass.<img src="https://photo-assets.superyachttimes.com/photo/396219/image/large-043a6cfbb4c2ee18f77e9eca62c4d295.jpg" data-gid="gid://syiq/Photo/396219">But heat is not the only issue. Full-height windows also eliminate the storage units and hidden cavities normally used to route ducting, wiring, and AC trunking, pushing the technical infrastructure inward. As a result, space became the defining constraint and the build team had to fight for every cubic centimetre. <a data-gid="gid://syiq/Company/33" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Hoek Design Naval Architects B.V. (Company)">Hoek Design</a> has deep experience of designing sailboats where space is always at a premium, but it was up to the shipyard to find ways to integrate complex systems into tight envelopes.“Nothing fitted, so we had to make it fit,” says Klaas, which could be the unofficial motto of the project. “By the time everything is installed, the engine room will be very full, but accessible and maintainable. Not cluttered – engineered.”The electrical switchboards span the full height of the engine from port to starboard across, an unavoidable result of the hybrid system. The engine room itself relies on seawater-fed heat exchangers because there wasn’t room for conventional air-cooling systems. The pool doubles as a tender bay with a dump tank and its own dedicated crane compartment that closes flush with the teak deck. Under the sunbed on the foredeck is a two-storey garage for the crew tender and a pair of PWCs. Add the elevator, wider side decks and interior passages sized for wheelchair access, and every available every void had to serve a purpose.<img src="https://photo-assets.superyachttimes.com/photo/396209/image/large-486995c89e482f3860ee5f1204771fb6.jpg" data-gid="gid://syiq/Photo/396209">Hidden in plain sightThe metallic bronze faux funnel is more than a charming styling cue; it also highlights the kind of engineering concealment that defines the whole project. Since the yacht has underwater exhausts, there was no need for a traditional dry stack – nor was there space to route ducting up to one. Instead, the funnel became the home of the fresh-air unit that draws in and purifies outside air for the HVAC system. Fitting it inside that tight volume meant some early design assumptions had to be reworked.&nbsp;Routing the air quietly around the yacht from high up in the vessel posed further challenges. The onboard noise targets are uncompromising and the owner’s suite is engineered for a harbour maximum of 44 decibels, although <a data-gid="gid://syiq/Company/40" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Royal Hakvoort Shipyard (Company)">Hakvoort</a> typically achieves lower. Underway, the expected levels sit in the low 50s – quiet enough that the only audible sound should be the soft splash of water along the hull. Modern superyachts achieve such low mechanical noise levels that airflow has become the primary acoustic concern, not the engines or generators.<img src="https://photo-assets.superyachttimes.com/photo/396212/image/large-a2aeb88e2ca030f7dc36a4bed74abb21.jpg" data-gid="gid://syiq/Photo/396212">“You won’t hear machinery these days – you’ll hear air moving through the ducting,” confirms Klaas. “That’s why we focus obsessively on silencing ducts, bends and terminations.”Consider the HVAC ducting for the crew quarters. To reach the lower deck forward, it has to pass under the bed in the owner’s stateroom, negotiating several dog-leg bends in the process. Air accelerates noisily through tight turns due to mass conservation and pressure shifts, so the yard routinely uses flexible elbow sections with larger diameters and internal damping to reduce turbulence and suppress sound. <img src="https://photo-assets.superyachttimes.com/photo/396214/image/large-892daf254a9606fb0d0d5fed5e58dda4.jpg" data-gid="gid://syiq/Photo/396214">Elegance with an edgeThe aluminium superstructure was built at <a data-gid="gid://syiq/Company/5231" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Alu-bouw Fryslân BV (Company)">Alubouw Fryslan</a> in Franeker and joined to the steel hull at Buijs Shipyard – the hull builder – before being towed to Monnickendam, but <a data-gid="gid://syiq/Company/40" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Royal Hakvoort Shipyard (Company)">Royal Hakvoort</a> has its own joinery division and stainless-steel department that produce most of the fixed furniture and deck hardware in-house. Klaas points out the custom-engineered hinges used for the exterior doors as an example of the shipyard’s hands-on approach. During development, these hinges were tested in the most practical way imaginable: by suspending 40 kg weights to a toilet door heavily used by shop-floor workers. Any weaknesses that surfaced were corrected before installation.&nbsp;Another example is the aluminium hull platform that folds out from the topsides amidships and connects to the main deck by way of a boarding ladder for tender access. The platform being assembled in the metalworking department uses a hydraulic rotary or slew drive – more compact than conventional rams and able to generate high torque in tight spaces, it is a solution that has been refined by <a data-gid="gid://syiq/Company/40" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Royal Hakvoort Shipyard (Company)">Royal Hakvoort</a> over years of building canoe-stern vessels.<img src="https://photo-assets.superyachttimes.com/photo/396211/image/large-9d9af2d4a7ba3a495473f7ac81ad923c.jpg" data-gid="gid://syiq/Photo/396211">Although capable of crossing the Atlantic, YB256 will primarily be used for short, comfortable runs with the frequent returns to port and high hospitality demands typical of most operational profiles. Every aspect of the interior has been conceived with wheelchair accessibility in mind, including a transformer-style platform in the stern. Guest and crew flows remain fully separated, which is not always the case on yachts of this size. The lower deck houses two full-beam VIP suites arranged around the main lobby and elevator; a third space will be used as an office/gym with a built-in recess for a running machine. The bridge deck is reserved for the owner’s sky lounge, while the captain’s cabin has been relocated to the lower deck. Crew areas have been configured to maximise discretion and operational efficiency with service and storage areas scaled to support day-use cruising.After touring the shipyard and the yacht, the lasting impression is that YB256 is not just a modern yacht in retro clothing. It is a study in constraint-driven design and smart engineering by a shipyard for whom “custom” is a vocation, not a marketing term. Its timeless elegance is more than skin deep, the result of many difficult decisions made in the belief that contemporary and classic can comfortably coexist – both in appearance and in engineering.<img src="https://photo-assets.superyachttimes.com/photo/396220/image/large-95656d748cc09cc4e461acdaecb835d0.jpg" data-gid="gid://syiq/Photo/396220">

<a data-gid="gid://syiq/Company/2027" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Castoldi S.p.A. (Company)">Castoldi</a>&nbsp;is both a leader in the field of waterjet technology and a point of reference for serial production tenders. Active across the military, commercial, and superyacht sectors, the Italian brand is now applying its propulsion and manufacturing know-how to the specialist market for limousine tenders.<img src="https://photo-assets.superyachttimes.com/photo/396631/image/large-062ebf001bce4c2cc3c7a9d7b4ad2e91.jpg" data-gid="gid://syiq/Photo/396631">The small town of Albairate in landlocked Lombardy might seem a strange place for a boatbuilder to set up shop, but it is closely linked to the brand’s origins in one of Italy’s richest agricultural regions. Luigi Castoldi was a pioneering engineer in the agricultural machinery sector through his company BCS, which is still extant today. He began exploring waterjet propulsion – still a novelty in the early 1960s – because boats were damaging their propellers on the shallow bottom of the nearby River Ticino.&nbsp;After importing a waterjet drive, he set about re-engineering it to create a more durable and effective design. His first mass-produced <a data-gid="gid://syiq/Company/2027" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Castoldi S.p.A. (Company)">Castoldi</a> waterjet, model Jet 05, made its debut at the 1969 Genoa Boat Show. Since then, over 40,000 <a data-gid="gid://syiq/Company/2027" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Castoldi S.p.A. (Company)">Castoldi</a> waterjets have been delivered around the world, from the compact 224 unit up to the mighty 600 HCT drive that can support installed power of up to 2,700 horsepower.<img src="https://photo-assets.superyachttimes.com/photo/396632/image/large-4d83f3db58d65cf02a38baa8d387c061.jpg" data-gid="gid://syiq/Photo/396632">Today, the company is still family-owned under the directorship of Giacomo Castoldi, Luigi’s grandson, who with his father Franco spearheaded the company’s diversification into the tender market with its own range of diesel-powered jet tenders. The first model, the JT 18 Pro in 1998, served as the blueprint for the current range, from the entry-level Jet Tender 14 up to the 10.5-metre Jet Tender 34. The latter also provides the technical platform for the Jet Tender 34 Limo, the company’s first venture into the limousine market.Why waterjetsWaterjet propulsion for superyacht tenders offers several advantages over traditional propeller-based systems. These include enhanced manoeuvrability, higher efficiency and durability, lower noise and vibration, and the reversing bucket can ‘crash stop’ a boat in less than twice its own length. But arguably the most critical feature – as Luigi Castoldi was quick to realise – is shallow draft.<img src="https://photo-assets.superyachttimes.com/photo/396635/image/large-accb3204fb1c42a0f2bfa16fdfac9f5c.jpg" data-gid="gid://syiq/Photo/396635">“Jet tenders can drive right up to a beach, and most of our models are equipped with bow ramps as standard,” says Giacomo Castoldi. “Combined with a folding console, low draft also means they occupy less vertical space inside the tender garage, while the lack of exposed propeller blades reduces the potential for injury to swimmers, divers, or marine life.”Over the years, <a data-gid="gid://syiq/Company/2027" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Castoldi S.p.A. (Company)">Castoldi</a> has finessed its waterjet technology. Unlike other systems requiring external gearboxes, all <a data-gid="gid://syiq/Company/2027" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Castoldi S.p.A. (Company)">Castoldi</a> waterjets except the entry-level Turbodrive 224 DD have integrated gearboxes. This results in a more compact overall footprint, which means more space for passengers and luggage storage, and simplifies the installation process while reducing the potential for errors or rework. They are also equipped with a patented anti-clogging system that enhances the waterjet’s reliability in challenging conditions. The Clear-Duct unclogging system works by reversing the direction of the impeller and simultaneously opening the protective intake grid to flush out any debris that may have accumulated.<img src="https://photo-assets.superyachttimes.com/photo/396660/image/large-44d8926e35b1304d60e5cdbcb14c3137.jpg" data-gid="gid://syiq/Photo/396660"><a data-gid="gid://syiq/Company/2027" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Castoldi S.p.A. (Company)">Castoldi</a>’s latest waterjet drives that carry the HCT acronym have been redesigned to offer a 12% increase in performance compared to previous iterations. Advancements in impeller design, a pre-stator vane system, and an updated post-impeller stator work together to improve the flow of water through the system, reduce cavitation, and ultimately deliver more thrust combined with lower fuel consumption.&nbsp;“These enhancements are largely thanks to investment in CFD analysis,” says Giacomo, “Combining fluid dynamics with our own practical engineering know-how has generated a lot of new ideas."<img src="https://photo-assets.superyachttimes.com/photo/396615/image/large-28e2be0f5dedca48b4f2f92405172d02.jpg" data-gid="gid://syiq/Photo/396615">Total control<a data-gid="gid://syiq/Company/2027" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Castoldi S.p.A. (Company)">Castoldi</a> also produces its own control systems, from simple mechanical options to the sophisticated ACES system developed in collaboration with <a data-gid="gid://syiq/Company/7877" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Xenta (Company)">Xenta</a>. Powered by a 32-bit embedded processor and utilising a proprietary CAN bus network protocol, the ACES system delivers precision control of engine RPM, waterjet steering nozzles and reversing buckets when transitioning between docking and cruising modes. Additional functions include dynamic positioning and smart anchoring, which simulates mechanical anchoring by swinging around a virtual GPS point. Adaptive steering logic can even provide ‘propeller mode,’ which recognises when the vessel is in reverse to simulate conventional propeller behaviour – a useful feature for operators transitioning to waterjets.To maintain quality control, most of the waterjet components are machined in-house, an exception being the Duplex stainless-steel impellers that rely on precision investment casting technology. With regard to tender production, the whole process – from the 3D design, hull lamination and tube fabrication to the hydraulic and electrical systems – is carried out internally before final testing in its own water basin in front of the factory.<img src="https://photo-assets.superyachttimes.com/photo/396658/image/large-b3c15147d7d49ce31a9b749e8a305ff2.jpg" data-gid="gid://syiq/Photo/396658">When <a data-gid="gid://syiq/Company/2027" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Castoldi S.p.A.

As the yachting industry begins to take alternative fuels seriously, Heikki Bergman, CEO and design manager of start-up company <a data-gid="gid://syiq/Company/8768" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Propulsion House (Company)">Propulsion House</a>, is several steps ahead. His company has developed a compact, modular methanol-electric propulsion system for yachts up to 70 metres that challenges the big marine technology brands.<img src="https://photo-assets.superyachttimes.com/photo/390298/image/large-6f876876617a86ea1297b4c7d5007042.jpg" data-gid="gid://syiq/Photo/390298">Drawing on more than two decades of experience in marine electrical propulsion, Heikki Bergman brings an engineering-driven approach to hybrid systems, with a sharp focus on real-world viability, space efficiency, and the practical constraints of small and mid-size vessels.“There’s good will in the market,” he says, “but not many customers or shipyards truly understand what they’re buying when it comes to electric or alternative-fuel systems. That’s where things often fall apart.”Now, Bergman and his team have unveiled a hybrid system he claims is capable of delivering over 5,000 nautical miles of range using methanol reformers, hydrogen fuel cells, batteries, and lightweight electric pod propulsion – all within the general arrangement footprint of an existing 45-metre, steel-hulled explorer hull designed by Frank Neubelt.<img src="https://photo-assets.superyachttimes.com/photo/390299/image/large-087f0ae7e1a2668b35e761bf7c22a0db.jpg" data-gid="gid://syiq/Photo/390299">Scaling downBergman’s journey began at <a data-gid="gid://syiq/Company/6143" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="ABB Group (Company)">ABB</a>, the Finnish leader in electrification and automation technology, where he worked on large commercial projects across Europe, particularly in the passenger vessel segment. In 2015, he identified a knowledge gap in the smaller vessel markets: while electrical and hybrid systems were becoming standard on larger ships, few people understood how to scale them down effectively for smaller yachts.&nbsp;"The big players don’t cater well to anything below 1 megawatt per propeller," he explains. "They come with massive project organisations and million-euro tickets, which just doesn’t work for yachts below 70 metres. We start from seven horsepower, up to 600 kilowatt."He founded <a data-gid="gid://syiq/Company/8768" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Propulsion House (Company)">Propulsion House</a> in 2017 as a consultancy, but it quickly evolved into a product development company. The firm now works across multiple sectors – including oil and gas – but yachting remains a core focus. The team doubled in size last year and is expected to grow again in 2026.<img src="https://photo-assets.superyachttimes.com/photo/390300/image/large-701d98e76c4b8100d4437b449c0de308.jpg" data-gid="gid://syiq/Photo/390300">Time to RethinkThe in-house propulsion system is a methanol-electric hybrid setup using the existing 45-metre explorer hull as a baseline that began with the team asking a simple but critical question: could a vessel of this size achieve 5,000 nautical miles of range using alternative fuels, without compromising usable interior volume? The answer: Yes, by completely rethinking how propulsion integrates with vessel design.At the heart of the system is the trademarked DeeCee Microgrid – a methanol-fuel-cell architecture designed for endurance, redundancy and modular installation. The system includes: six methanol reformers, which convert a methanol/water mixture into hydrogen and CO₂; six 200 kilowatt hydrogen fuel cells, fed by the reformers to generate electricity; and two 600 kilowatt battery banks, offering load balancing, peak shaving, and full-electric operation in port or during silent cruising.<img src="https://photo-assets.superyachttimes.com/photo/390301/image/large-09f5baddc586600638d912e42f93dd0f.png" data-gid="gid://syiq/Photo/390301">All the system components – fuel cells, batteries, converters – are already commercially available. Combined, they enable propulsion via two 600 kilowatt electric pods, with no shaft lines or central switchboards. Instead, the vessel uses a distributed DC network through localised electrical control units – each managing its zone independently and able to switch within milliseconds in case of blackout.“We’ve eliminated the need for a switchboard room altogether,” says Bergman. “This frees up interior volume, reduces cabling, and improves safety and redundancy.”The reforming process produces a controlled volume of CO₂, which the system can capture and store onboard for recycling. The volume of this captured CO₂ is significantly lower than from internal combustion engines – about 40-60 percent less than a diesel generator. Moreover, when taking into production methods of green methanol and e-methanol, some of which actually consume CO2 rather than release it into the air, the overall CO2 emission reduction is even higher.<img src="https://photo-assets.superyachttimes.com/photo/390305/image/large-8b7413485de1c405fa96aac8b215fe00.jpg" data-gid="gid://syiq/Photo/390305">Small, Light &amp; SmartPerhaps the most radical part of the concept is the proprietary Pulling-e Propulsion pod design. It resembles a torpedo: long, narrow, and hollow, with a stationary internal body, an outer rotating propeller shell and a 2-bladed propeller offering a good balance of efficiency and drag. Containing a permanent magnet synchronous motor and scalable from 7-600 kilowatt per propeller, there is no shaft, no gearbox, and minimal mechanical complexity. The pod can be steerable for shallow water use, or fixed with a rudder integrated into the strut that connects it to the hull.&nbsp;The unit is designed to be modular and installation-agnostic. It can be fixed horizontally to the hull, retrofitted into an old rudder socket, or even fitted with lift-enhancing struts to improve hydrodynamic flow. Unlike traditional azimuthing thrusters, which rotate 360 degrees, the pods limit steering angles but compensates via bi-directional rotation. The result is full-vector thrust control, achieved with a simpler, lighter system.<img src="https://photo-assets.superyachttimes.com/photo/390304/image/large-1e7154665ec390b5c89b7ed5b892f2e1.jpg" data-gid="gid://syiq/Photo/390304">This method also benefits noise reduction. The methanol-electric propulsion is already quiet, so the remaining main source of noise is from propeller-generated pressure pulses hitting the hull. The propellers, positioned far aft as far outboard as possible away from the hull, significantly reduce this underwater radiated noise—a growing concern for marine ecosystems.The concept isn’t just theoretical. Cambridge University’s Energy boat challenge team recognised the potential and <a data-gid="gid://syiq/Company/8768" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Propulsion House (Company)">Propulsion House</a> has been working with Marin’s top designers on the propeller optimisation, using a 15-kilowatt test unit to refine efficiency. The propellers were optimised using PropArt and PROCAL computations. A speed-power prediction based on the resistance was provided, and additional analysis was carried out in terms of steering forces and cavitation behaviour.<img src="https://photo-assets.superyachttimes.com/photo/390303/image/large-fe5f36bdbe69c88da2bda09491ac7329.png" data-gid="gid://syiq/Photo/390303">“We achieved 89 percent propeller efficiency – among the highest on the market,” says Bergman. “And when we scale up to the size used on yachts, efficiency actually increases due to the larger central hole in the propeller. And that’s just the first iteration available.”The system is also suited for retrofits. In theory at least, shaft lines could be removed entirely and the new propulsion unit installed into the existing rudder sockets, reducing the need for invasive hull perforations. The structural load is carried in a way similar to rudder mechanics, with reinforcement achieved by increasing material thickness inside the torpedo's cooling pipe. <img src="https://photo-assets.superyachttimes.com/photo/390302/image/large-279388f3d090554f024470e1514e9ec4.png" data-gid="gid://syiq/Photo/390302">A New Design OrderPerhaps most radical is the company’s approach to vessel design itself. “We start from the underwater section,” Bergman explains. “First the hull, then the propeller location, and then everything else. Not the other way around.”This inverted design process contrasts with the traditional method of selecting off-the-shelf propulsion systems first, which often forces compromises in hull shape, hydrodynamics and interior layout.With partners already on board for further testing in 2026, and interest growing among shipyards and owners, <a data-gid="gid://syiq/Company/8768" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Propulsion House (Company)">Propulsion House</a> is positioning itself not just as a technology provider, but as a strategic design partner. By simplifying systems, reducing space usage, offering real redundancy, and embracing cleaner fuels, Bergman believes a better class of hybrid yacht is not only possible – it’s ready to build. “There’s no fantasy here,” says Bergman. “This could be built tomorrow.”&nbsp;

Inside the push for methanol-electric yacht propulsion with CEO Heikki Bergman

If home is where the hearth is, then the galley is certainly a fundamental element of any superyacht. Whether enjoying a 10-course taster menu or a teppanyaki treat on deck, food is central to the onboard experience. We take a look at how to avoid second-rate cooking spaces and equipment.When people talk about superyachts, the highlights always seem to revolve around the same things: the beach club, the sundeck, the pool, the master stateroom. The galley barely gets a second thought, until you spend time on board –&nbsp;then the food and its service take centre stage and any issues to do with layout, design or installation become belatedly obvious.Naturally, safety is paramount. Galleys present a host of hazards from deep fryers and steamers to rotating equipment and sharp blades. Fire suppression, hygiene, ventilation, materials, and so on, are governed by classification society rules, but small details like having rounded internal radii instead of sharp corners in stainless steel cabinets help prevent dirt accumulation and make cleaning much easier for galley staff. Ergonomics and design are equally important.<img src="https://photo-assets.superyachttimes.com/photo/394386/image/large-95000aca9788e63f3727ba677f1045e1.jpg" data-gid="gid://syiq/Photo/394386">“The galley layout is defined according to the capacity of the yacht, considering both guests and crew,” says Costanza Pazzi, project architect at <a data-gid="gid://syiq/Company/12" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="CRN (Company)">CRN</a>. “It is usually designed with three clearly distinct areas: washing, cooking, and preparation.”Separate traffic flows for clean and dirty dishes help prevent cross-contamination and accidents. Adequate lighting is a sometimes overlooked consideration, especially for galleys on the lower deck with smaller windows where the artificial lighting should emulate daylight temperatures (4000K-5000K) to show the true colour of the food being prepared.“Each custom superyacht galley is different,” Pazzi continues. “The spaces dedicated to galley and pantries should be discussed as part of the technical specifications at contract completion, with guidelines coming directly from the owner’s team. A fundamental requirement is that ducting and systems need to be defined in the general plans from the outset.”<img src="https://photo-assets.superyachttimes.com/photo/394417/image/large-7799ab22eb4f8b77c27d0e82de2c9dc0.jpg" data-gid="gid://syiq/Photo/394417">Experience counts“The galley is not just one room – it’s an entity,” says Brennan Dates, a chef with more than 25 years’ work experience on superyachts.

Which deck is the galley on? Where are the pantries and which decks are the guests eating on? Some food is stored in the galley, then it gets prepped, possibly stored again, then gets heated or reheated, plated and served, and now you’re talking about pantry flow.” <img src="https://photo-assets.superyachttimes.com/photo/394418/image/large-c4c49eab3aaeeb1639265cfacfe9f9ee.jpg" data-gid="gid://syiq/Photo/394418">It’s also important to consider the operational profile of the yacht, because there’s a difference between a purely private yacht and one that’s going to be busy chartering. Is it going to be doing extended cruising to remote locations, which may require bigger dry stores and cold rooms?“I can walk into a galley and within five minutes know if there was a yacht chef involved in the build,” says Dates. “But no one’s really listening to chefs at this point, and I think that negatively impacts on the whole guest experience, but also the crew.”<img src="https://photo-assets.superyachttimes.com/photo/394416/image/large-f89be51556d3eb7510c568074aeb1395.jpg" data-gid="gid://syiq/Photo/394416">One thing for sure is that dumb waiters are mostly a thing of the past, with crews preferring to use the space for additional storage or fridges. Dates further warns against the use of domestic kitchen appliances on board in what are essentially commercial kitchens, where stuff tends to break down much faster. “Rational is the number one in the world for ovens, and MKN is up there,” he advises. “There’s a precipitous drop after those two.”On-deck delightsThese days, the galley is only one centre of chef action on board. There will likely be outdoor cooking stations in the build plan, particularly on charter yachts. <a data-gid="gid://syiq/Company/23" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Lürssen Yachts (Company)">Lürssen</a>’s <a data-gid="gid://syiq/Yacht/6424" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Hadar136.0m (446'2&quot;)Lürssen Yachts2019">Hadar</a>, for example, features an extensive outdoor kitchen on the bridge deck aft, where guests can watch the chef working a wok station, a coal-powered Spanish Josper grill, a rotisserie, and pizza/teppanyaki/tandoori ovens.&nbsp;“At a bare minimum there needs to be a sink and refrigeration, just for basic sanitation,” Dates says. “If you can have a little trash compartment that’s sealed away that’s useful, and then it comes down to equipment – there’s a really good oven by MKN that fits under the counter and which takes care of its own exhaust and accepts standard 535x325 millimetre gastronomic trays.”“There is an ever-increasing demand for the inclusion of pizza ovens, particularly for yachts over 60 metres,” adds Pazzi, “There is also a trend for a table in the main galley where guests have the chance to see the chef working and enjoy a food tasting, aimed at creating a sensory experience.”&nbsp;Open-plan, country kitchen-style layouts are increasingly popular on smaller yachts, and on “galley-up” catamarans where the cooking area become an integral part of family life on board. The <a data-gid="gid://syiq/Company/374" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Sanlorenzo (Company)">Sanlorenzo</a> 64Steel <a data-gid="gid://syiq/Yacht/6178" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Attila64.0m (209'12&quot;)Sanlorenzo2019">Attila</a> even has a custom-made barbecue pit inside the main deck dining area for preparing Argentinian-style steaks. <img src="https://photo-assets.superyachttimes.com/photo/394422/image/large-e484db9dd7caca3e714a505d18be3385.jpg" data-gid="gid://syiq/Photo/394422">Breathing easyAlongside cooking comes the risk of odours, which can quickly infiltrate indoor guest areas if ventilation and extraction aren’t properly designed. During the design of the second <a data-gid="gid://syiq/Yacht/11108" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Moonrise100.7m (330'5&quot;)Feadship2025">Moonrise</a>, for example, the owner requested a taller mast so galley fumes are not blown back onto the sundeck after being vented.&nbsp;&nbsp;The air extraction system in the pro-spec galley aboard the 76.6-metre explorer yacht <a data-gid="gid://syiq/Yacht/4734" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Albatross76.6m (251'4&quot;)Piriou2015">Albatross</a> highlights how smart design can maximise energy efficiency. Extractor fans typically suck the air out of a room, which has to be replaced anew with fresh, treated air. But when the outside temperature is -20°C that could mean firing up another generator just to reheat the air because the galley is in use. On <a data-gid="gid://syiq/Yacht/4734" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Albatross76.6m (251'4&quot;)Piriou2015">Albatross</a>, the cowling above the cooking hobs also creates a curtain of treated air that effectively isolates the cooking area, saving HVAC energy while containing cooking odours and maintaining a constant temperature in the galley. A similar system has been installed on the all-electric sailing yacht Project Zero.<img src="https://photo-assets.superyachttimes.com/photo/394426/image/large-b6d6a20d4c21394ec767a94b34324a08.jpg" data-gid="gid://syiq/Photo/394426">Galley design extends to the handling of waste produce, which includes both garbage and wastewater treatment. The latter is particularly pertinent, because food contaminants and grease can wreak havoc with onboard water treatment systems (this topic is specifically addressed in <a href="https://issuu.com/superyachttimes/docs/how_to_build_it_-_issue_9" rel="noopener noreferrer" target="_blank" title="">Issue 9&nbsp;</a>of How to Build It).&nbsp;“Fat, oil and grease (FOG) need to be separated – this is very important not only for the wastewater treatment process, where they can affect the biological process or clog filters, but also to prevent clogging of pipes,” confirms Georgios Kariofilis, Sales Manager at <a data-gid="gid://syiq/Company/8602" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Hamann AG (Company)">Hamann</a>. “Having a grease trap and a pre-filter system is the first step to avoiding such problems.”Organic trash handling, typically resolved by storing garbage in a refrigerated room or in a deck locker, is also making advances. Dehydration plants, such as those offered by Evac and Eco-Smart, remove water content from food waste by heating it to around 80ºC and evaporating it off as steam. The sterile and odourless residual food waste is roughly 15 to 20 percent of its former volume and can be stored more easily on board for later disposal or composting. Essentially, it means you don’t need as big a trash storage room.<img src="https://photo-assets.superyachttimes.com/photo/394420/image/large-a3eda501d5fdaf6da7497de827b67522.jpg" data-gid="gid://syiq/Photo/394420">Ask an expert&nbsp;The advice from designers and chefs is basically to bring in an expert at the layout stage of design, and to argue for more space rather than less, no matter the size of yacht. Speciality companies like UK-based <a data-gid="gid://syiq/Company/2137" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="GN Espace Galley Solutions Ltd (Company)">GN Espace</a> offer expert advice for superyacht galley layouts and equipment spec, including full commercial galleys and upgrades such as adding a robust powder coated finish to stainless steel doors to match the rest of the yacht.Large or small, yacht designer Guido de Groot argues that the galley is generally in full-time use – especially on charter vessels. He compares the 10 guests plus eight crew aboard the 35-metre <a data-gid="gid://syiq/Company/2948" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Van der Valk Shipyard (Company)">Van der Valk</a> yacht <a data-gid="gid://syiq/Yacht/13018" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Lalabe35.31m (115'10&quot;)Van der Valk Shipyard2025">Lalabe</a> with a 50- or 60-metre vessel that might have 12 guests and 14 crew.“It’s a similar number of guest and crew, so you can’t just halve the size of the galley on the smaller yacht,” he points out. “It requires a lot of smart thinking to get everything into a more compact space.”“Give the galley and associated areas the space they deserve,” insists Dates. “Is luxury jamming the galley in the bottom of the boat and having food travel up four decks, or is it spending resources to have the galley on the main deck nearer to where guests will eat? Because that’s what I would want.”<img src="https://photo-assets.superyachttimes.com/photo/394419/image/large-c9630b9438c0f3772c24b74a369972a1.jpg" data-gid="gid://syiq/Photo/394419">Shipyards looking to streamline the planning process with standardised solutions sometimes argue against bringing in a consultant chef at the design stage. All chefs have their own routines, preferred equipment, likes and dislikes, but individual chefs do not stay with a yacht indefinitely. The galley, on the other hand, will remain for many years, or at least until a major refit. &nbsp;“Not including a superyacht chef in the build is like building a race car and not talking to the driver because they’ll want different buttons in different places,” counters Dates. “It doesn’t make any sense to have someone who’s never done the job be the one to put it all together.”

More than a speculative future concept, the AERA catamaran represents the convergence of mature technologies assembled with an emphasis on simplicity and sustainability. Research and testing have shown the project is both feasible and buildable. The focus now is on systems integration and production scaling.<img src="https://photo-assets.superyachttimes.com/photo/371664/image/large-bcc3594f61ee7b5986053ac54a532b0c.jpg" data-gid="gid://syiq/Photo/371664">Developed by <a data-gid="gid://syiq/Company/122" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Royal Huisman (Company)">Royal Huisman</a> in collaboration with sister company <a data-gid="gid://syiq/Company/458" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Rondal B.V.

Rover Design (Company)">Cor D Rover</a>, AERA is a technical study into the feasibility of combining wind-dominant propulsion, low-drag hydrodynamics and alternative energy systems within the constraints of a large luxury yacht.&nbsp;The 50-metre catamaran builds on the shipyard’s Project Tidal Shift, an internal innovation initiative that identified increased utilisation of sail power and systemic reductions in energy demand as the most effective pathways towards sustainability. From the outset, the project followed an engineering-first methodology in which energy demand and drag were reduced before alternative energy sources were applied. This approach informed decisions across platform selection, structural engineering, rig design and onboard energy systems.“Early concept development did not initially assume either a multihull platform or a wing sail,” says Herman de Jong, innovation manager at <a data-gid="gid://syiq/Company/122" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Royal Huisman (Company)">Royal Huisman</a>. “Our initial investigations focused on automation of conventional rigs and the use of delivery sails to reduce dependence on costly sail inventories.”Collaboration with <a data-gid="gid://syiq/Company/7904" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Artemis Maritime (Company)">Artemis</a> introduced the possibility of wing-based propulsion, with early consideration given to soft wing concepts derived from high-performance foiling monohulls. These were ultimately rejected due to the large structural loads required to shape the membrane, the resulting rig forces transferred to the hull, and the limited suitability for the operational profile of a superyacht. A rigid wing sail was identified as aerodynamically superior, functioning as a true air-foil with 10 times lower drag than a conventional tube mast (even with the sails lowered), while also allowing passive feathering when unloaded.<img src="https://photo-assets.superyachttimes.com/photo/371695/image/large-f6fba2ad9ba66c269310feeea6a26fee.jpg" data-gid="gid://syiq/Photo/371695">Active control“Wing sails have been proven in racing environments such as the America’s Cup and <a data-gid="gid://syiq/Company/6878" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="SailGP (Company)">SailGP</a>,” argues Dr Iain Percy, founder and CEO of <a data-gid="gid://syiq/Company/7904" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Artemis Maritime (Company)">Artemis Technologies</a>, himself an AC veteran and double Olympic champion. “The challenge here is adapting that performance into a reliable, low-maintenance system suitable for a superyacht. To do that, a significant part of the development has focused on active control to manage performance, comfort and manoeuvring across a wide range of conditions.”Initial testing of the wing concept was conducted using a free-standing, rotating carbon-fibre wing mounted on a J22 test platform. The trials confirmed the wing’s ability to passively align with the wind and maintain low drag, but also revealed some dynamic coupling between the wing’s oscillatory behaviour and the natural roll frequency of the monohull. These findings convinced the team to focus on a multihull configuration, as the increased initial stability of a catamaran minimises roll-induced excitation of the wing system and the loads on the two sets of bearings inside the yacht, although <a data-gid="gid://syiq/Company/122" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Royal Huisman (Company)">Royal Huisman</a> does not preclude monohull applications in the future.<img src="https://photo-assets.superyachttimes.com/photo/371647/image/large-3db5887279a6542cf289be78a33db442.jpg" data-gid="gid://syiq/Photo/371647">“The wing sail concept is better suited to a catamaran platform as the rig remains upright and is not subjected to large heel-induced load variations,” explains de Jong. “By limiting heel angles, the vessel also avoids one of the primary deterrents for owners transitioning from motor yachts to sailing yachts, not to mention the absence of flogging sails and running rigging.”The wing comprises a thin aerodynamic Mylar skin supported by a carbon-fibre framework of spars, ribs and transverse plates, which manage the global bending and torsional loads much like the wings of an airplane. Controlled flexibility is incorporated into the design to allow the wing to twist under load, improving lift distribution and reducing peak stresses. <img src="https://photo-assets.superyachttimes.com/photo/371658/image/large-87c2c4becc7abb55160fd76750f46e73.jpg" data-gid="gid://syiq/Photo/371658">AutomationAutomation is fundamental to the operational viability of the wing system. Conventional sail handling is replaced by wing rotation and deflection of the four trailing-edge flaps, actuated by hydraulic cylinders at the root of each flap. Sensor-driven software continuously adjusts the wing’s angle of attack and flap configuration in response to wind conditions, reducing crew workload and minimising the risk of human error. The control algorithms are the result of CFD models developed in collaboration with Artemis, drawing on experience from high-performance sailing applications.&nbsp;Feathering is a critical safety feature, so if the active system fails the wing naturally aligns with the wind and minimises drag. In extreme or turbulent conditions, it is designed to depower automatically to a low-load, low-drag state without requiring crew intervention. Although it’s designed to remain upright in all weather conditions, a hydraulic hinge mechanism allows the entire wing to be lowered to reduce air draught for bridge clearance or maintenance purposes. <img src="https://photo-assets.superyachttimes.com/photo/393334/image/large-cbf9c3c68a163712f4ddc521e251b194.png" data-gid="gid://syiq/Photo/393334">From a lifecycle standpoint, Dr Percy points out that a wing sail replaces a consumable system with a permanent one. Conventional sails degrade and require regular replacement, whereas a properly designed wing can last for the life of the yacht. This permanence shifts cost and maintenance considerations away from periodic sail replacement towards upfront engineering and long-term reliability.“Manufacturing feasibility has also been a central consideration throughout development,” says Bart van der Meer, sailing system engineer at <a data-gid="gid://syiq/Company/458" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Rondal B.V. (Company)">Rondal</a>. “Each rib of the wing requires a unique mould due to the changing airfoil geometry along the span. We expect production-scale moulds are expected to be fabricated from milled aluminium to ensure dimensional accuracy and repeatability.”Although these challenges are not trivial, they are a question of process optimisation rather than unresolved technical risk.<img src="https://photo-assets.superyachttimes.com/photo/393329/image/large-e0fb3f469c6062ee583c2c1998445a5c.jpg" data-gid="gid://syiq/Photo/393329">Built like a bridgeStructurally, the AERA catamaran departs from conventional multihull architecture through the use of principles derived from cantilevered bridge design – notably the historic Koningshaven Bridge (also known as ‘De Hef’) close to <a data-gid="gid://syiq/Company/43" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Cor D. Rover Design (Company)">Cor D Rover</a>’s studio in Rotterdam. The triangulated geometry spans large distances between pillars, enabling open-plan interiors and extensive glazing without visually dominant pillars.&nbsp;The asymmetrical geometry of the vessel is a functional response to spatial and structural requirements rather than an aesthetic gesture. Although the deck levels appear unsupported, structural integrity is maintained through clearly defined global load paths disguised in features such as staircases. <img src="https://photo-assets.superyachttimes.com/photo/371698/image/large-b28b9a6de23b265903ea61bfe20d603d.png" data-gid="gid://syiq/Photo/371698">“The geometry follows the forces rather than being applied as a stylistic layer,” explains <a data-gid="gid://syiq/Company/43" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Cor D. Rover Design (Company)">Cor D Rover</a>. “Structural cut-outs allow semi-open areas to remain outside the tonnage calculations while still contributing to stiffness and spatial articulation. Despite this unconventional arrangement, the enclosed volume is carefully controlled at approximately 1,880 cubic metres, keeping the vessel below the 500 GT threshold.”Material selection for the hull and superstructure is centred on aluminium, chosen for its strength-to-weight ratio, recyclability, and compatibility with <a data-gid="gid://syiq/Company/122" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Royal Huisman (Company)">Royal Huisman</a>’s expertise in working with lightweight aluminium alloys.

At these speeds, continuous power output of around 40 kW is achievable, sufficient to cover hotel loads and allow generators to remain offline. The fixed, low-drag hydrogenerators deliver optimal performance without the added complexity of retraction mechanisms – a solution that aligns with AERA’s ethos of simplicity and high efficiency.<img src="https://photo-assets.superyachttimes.com/photo/393328/image/large-15f017ba3b5bb5892a3a52ed2dc5ad1c.jpg" data-gid="gid://syiq/Photo/393328">“Our simulations show that during a typical cruising week, including one visit shoreside when shore power is available, the yacht will not need to run her variable-speed gensets for hotel loads,” says Jidde Looijenga, innovation manager at <a data-gid="gid://syiq/Company/122" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Royal Huisman (Company)">Royal Huisman</a>. “They are needed only during motoring or motor sailing to generate electricity for the retractable propulsion system.

Any such system would be supplementary rather than critical and, as the designer notes, “would need to operate with very low noise and vibration to be acceptable in a yacht environment.” These ideas are not on the project’s critical path, but they illustrate potential future extensions of <a data-gid="gid://syiq/Company/122" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Royal Huisman (Company)">Royal Huisman</a>’s renewable energy strategy.<img src="https://photo-assets.superyachttimes.com/photo/393332/image/large-3aaca815d143ace4293d0ef4519ca552.png" data-gid="gid://syiq/Photo/393332">UsabilityBeyond technical feasibility, the AERA concept also addresses usability and the owner experience. The combination of automation, reduced manual sail handling, and increased comfort is intended to make sailing more accessible and as straightforward as operating a motor yacht.&nbsp;“Combined with reduced fuel consumption and lower operational emissions, this positions AERA as a bridge between motor and sailing yacht ownership,” says Looijenga.Overall, the catamaran represents a convergence of proven technologies and disciplined system integration rather than reliance on untested innovations. With its emphasis on simplicity, sustainability and lifecycle efficiency, the concept demonstrates that a wind-dominant, low-emission superyacht is technically achievable within available engineering and classification frameworks.<img src="https://photo-assets.superyachttimes.com/photo/371693/image/large-d494cdf4de75a63242521821d563f54f.png" data-gid="gid://syiq/Photo/371693">

AERA catamaran: The wind-dominant, low-emission sailing superyacht

Starting out as a captain, Simon Finlayson quickly found himself drawn into the mechanics of new-build decision-making – first as a build captain, then as an owner’s representative. Recognising the value of understanding how yachts are built from the inside out, he moved into the yards, working within both project management and production team, to close the knowledge gap between owner expectations and shipyard execution.<img src="https://photo-assets.superyachttimes.com/photo/390228/image/large-d82f02d6f20048f162b3e9f36ff01c3a.jpg" data-gid="gid://syiq/Photo/390228">You’ve worked across both sailing and motor yachts. What’s the biggest practical difference from a build perspective? A sailing yacht spends much of its life heeled over, while a motor yacht generally operates upright but rolls. That single reality drives countless knock-on decisions. Something as basic as getting suppliers to confirm their equipment will operate at heel sounds simple, but it’s a major consideration that can be overlooked until late in the process. Beyond that, industry culture differs. Sailing yacht teams often have more human connection and personal involvement in material choices and how the boat comes together. Motor yacht projects, especially at the larger end, tend to be more contract-led – lines are more clearly defined, and communication can become more formal and legalistic.<img src="https://photo-assets.superyachttimes.com/photo/372358/image/large-f8a547ead4e5dc9366a98d8c53b3ebb5.jpg" data-gid="gid://syiq/Photo/372358">Where do sailing yacht builds demand the most attention during construction? Construction and engineering discipline – particularly strength versus weight and load management. Sailing yachts face more dynamic load cases than motor yachts. Rig, structure, deck gear, and load paths have to be correct because the forces are very real and move around the boat depending on sail plan and conditions. Then there’s the constant balancing act between complexity, available space, and operational simplicity. You can specify incredible technology, but someone has to operate it while also sailing the yacht. It’s very easy to spiral into systems that are elegant on paper yet impractical at sea.You mentioned technology can become a “rabbit hole”. What does that mean in practice? It often starts with good intentions: more automation, more integration, more capability. Engineers are focused specialists and can build something technically impressive. But if the operational interface becomes too complex, the crew won’t embrace it, faults become harder to diagnose, and the yacht ends up carrying systems that don’t truly help. The challenge is finding a workable middle ground – systems that deliver performance without turning routine operation into an engineering exercise.<img src="https://photo-assets.superyachttimes.com/photo/106261/image/large-8723f43ab69bd20d62467c9657646233.jpg" data-gid="gid://syiq/Photo/106261">You’ve been brought into projects to assist with re-aligning goals and expectations. What’s your go-to framework for getting control quickly? I try to keep it simple and scaleable: what did you say you would do, what are you doing now, and does that still fit our expectations?’ Then keep looping that conversation until everyone agrees on what “done” looks like. It’s mostly expectation management – but grounded in facts, not opinions.How do you bring shipyard processes into sync with specialist contractors and designers? By respecting expertise. If I come to you for doors, it’s because you’re the best at doors – you should advise how to solve the problem. Shipyards can sometimes push a “we always do it like this” approach, but many suppliers have good reasons for their preferred methods. In the Netherlands especially, you see deep specialisation. The industry is successful because experts can operate within a niche at the top end of their field. The best outcomes come when you give that expertise space, listen, acknowledge it, and then clearly define demarcation and deliverables.<img src="https://photo-assets.superyachttimes.com/photo/185959/image/large-e9814fcc0864c8409951eb957946f58b.jpg" data-gid="gid://syiq/Photo/185959">Where do schedules most commonly come under pressure on new builds? There are typically two pinch points. First is the start of construction. Different yards approach engineering and production differently. Some “engineer, then build”, while others start building early to protect the programme. Either way, you need clear decision gates – moments to say, “we know enough to proceed,” or equally, “we don’t know enough yet, so stopping now prevents rework later.”Then there is finishing and acceptance. Getting from a dynamic production environment to a finished, accepted space or system requires a high level of coordination. Someone has to confirm it is correct – yard-side or owner-side – and that acceptance can &nbsp;proceed based on facts rather than opinions. It requires checking, testing, cleaning, close-out, and a shared understanding of what remains outstanding. It’s easy to reach the end of hours or budget and declare, “it’s done.” In reality, that’s often the start of the hard part: delivering something that can be signed off with confidence.<img src="https://photo-assets.superyachttimes.com/photo/367902/image/large-6b292765f8464aaae3fe8b1c81e49d1e.jpg" data-gid="gid://syiq/Photo/367902">Change orders can lead to major timeline extensions. Can they be prevented? Not always. The first question is whether the change is driven by necessity or desire. Sometimes change is essential for safety, practicality, compliance, or evolving technology. The key is catching it early enough to minimise impact, and that brings us back to the one tool that matters at every level: the specification. Every conversation – with the owner’s team, suppliers, and within the yard – should orbit the spec. The moment you realise you’re discussing something that wasn’t agreed, you stop and reset: why are we talking about this change, what decision is required, and how do we proceed? If you lose the spec, you lose control.&nbsp;What technical trends are most likely to influence yacht building over the next decade? Propulsion and energy architecture will determine the technological backbone of future yachts. Moving toward battery-driven propulsion and DC-based electrical systems rather than traditional AC isn’t a bolt-on change – it affects the entire vessel. It requires a shift in engineering knowledge, build experience, and operational capability. You can design these systems, but they must be simple enough for the crew to operate. If nobody can operate it, you can’t build it – at least not responsibly.Another major theme is materials availability, with teak decks becoming a particularly visible battleground. It’s not only about sourcing; it’s about persuading stakeholders to rethink what a “proper” deck should look and feel like. The industry is, by nature, building the future using the past. That’s powerful, but it can also trap you in familiar solutions when the best answer is changing.<img src="https://photo-assets.superyachttimes.com/photo/113629/image/large-ebbb6667281aa6927f85947a0a313e82.jpg" data-gid="gid://syiq/Photo/113629">You’ve been involved in some standout yachts. Which projects most shaped your approach as a project manager? <a data-gid="gid://syiq/Yacht/4241" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Wisp47.65m (156'4&quot;)Royal Huisman2014">Wisp</a> was a pivotal learning curve – a classic sailing yacht build that showed me how much I still didn’t know about shipyard reality, even when deeply involved on site. Later, working inside a shipyard environment at De Vries on major deliveries such as Moonrise and Bliss accelerated my understanding of just how complex coordination can be.The real benchmark for me, though, has been the <a data-gid="gid://syiq/Yacht/6409" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Moonrise99.9m (327'9&quot;)Feadship2020">Moonrise</a> programme, because I experienced it from both sides – first for the shipyard and then within the owner’s team on the subsequent project, <a data-gid="gid://syiq/Yacht/11108" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Moonrise100.7m (330'5&quot;)Feadship2025">Moonrise II</a>. That provided a complete view of how decisions, quality control, documentation, and delivery pressures differ depending on where you sit.When design intent is clear and the drive for quality is genuinely high, you get something rare: a yacht where you walk through and everything feels right – layout, flow, system logic, and finish. Being part of that elevates your own performance and sets a standard you try to carry into every other project.

We were working with just a few thousand square metres compared to 10-20,000-square-metres on some of our larger projects. However, the time investment was comparable. This is because of the level of complexity and detail it required. We were working to an inspection tolerance of just 1.5 millimetres over three-metres – an unprecedented level of flatness and consistency for a yacht of this size. Achieving this meant deploying up to 16 highly skilled specialists on the project. Material choice added another layer of difficulty. The design required a blue pigment, which is among the most challenging colours to stabilise in resin-based systems. In many ways, we weren’t simply delivering a deck – we were realising a design object in its own right. <img src="https://photo-assets.superyachttimes.com/photo/374254/image/large-dd7155f66c665783416d641846d8d349.jpg" data-gid="gid://syiq/Photo/374254">How is R&amp;D currently shaping the development of synthetic decking?UV resistance is a major focus. Owners expect colour stability over many years, even with constant exposure in extreme climates, so improving long-term performance under UV load is critical. We’ve also developed so-called “cool pigments” and techniques to reduce surface temperature, making decks more comfortable to walk on in hot regions. We can now embed functional lighting directly into the deck. One example is helicopter landing areas: using gyroscopically informed lighting, the system changes colour in response to vessel movement, giving pilots immediate visual feedback on whether conditions are safe to land. This technology originated from our work on naval frigates, where safety requirements are uncompromising. Beyond materials, we are becoming much more data-driven as a company. By integrating sensors into decks, we can analyse how people move and behave onboard, allowing us to optimise functionality and safety.<img src="https://photo-assets.superyachttimes.com/photo/374247/image/large-6da0558a1b1f317874e656c98e57635a.jpg" data-gid="gid://syiq/Photo/374247"> We still see a lot more teak decks on new builds than synthetic ones and it appears that, outside of technical areas, owners still want wood. What are your thoughts on this?&nbsp;We do see a shift in mindset, but we’re in a transition phase. When something old and familiar comes under pressure or begins to disappear, people initially look for something that comes as close as possible. Designers and owners often fall back on materials that reference familiar imagery and heritage, driven by aesthetics and emotion. In that search, choices are frequently made based on visual similarity, even if that means compromising on performance or longevity. That tendency usually persists until real-world use reveals that these materials age differently from the original, for example, by degrading more quickly or lacking essential properties such as wear resistance, or resistance to porosity and water absorption. At that point, the question shifts away from what looks similar, towards materials that not only feel right aesthetically, but also perform demonstrably in practice.<img src="https://photo-assets.superyachttimes.com/photo/378026/image/large-e1d52fec9f5b48e54ce4354cd6459c91.jpg" data-gid="gid://syiq/Photo/378026"> As CEO, how do you see the future of&nbsp;<a data-gid="gid://syiq/Company/7672" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Bolidt (Company)">Bolidt</a>?The COVID period pushed many businesses into short-term, crisis-driven thinking and disrupted the relationship-building that normally underpins innovation. Now, in 2026, we can once again focus on long-term strategy. My focus is on innovation and striving to have a continuous process. At <a data-gid="gid://syiq/Company/7672" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Bolidt (Company)">Bolidt</a>, that means an extended horizon and we talk about thinking 500 years ahead – not because it’s literally achievable, but because it shapes how we make decisions today. That mindset encourages durability, adaptability and responsibility in everything we develop.Finally, we are very excited about showing people all the innovative things we can achieve as a company and so we’ve built a two-storey Experience Centre of 4,000-square-metres where architects, designers, and industry professionals can see what’s technically possible. We’re keen to actively challenge the industry’s thinking and we want people to engage, question assumptions, and reimagine what’s possible with decking.

Which cities can truly claim that their ports are as old as the cities themselves? Hamburg is one of the few. Its maritime heritage permeates every corner, thanks in large part to Hermann Blohm and Ernst Voss.<img src="https://photo-assets.superyachttimes.com/photo/388030/image/large-2b7a5af8e354717e8822a2c8e928c86f.jpg" data-gid="gid://syiq/Photo/388030">The two German entrepreneurs, whose names still proudly brandish the shiplifts that define Hamburg’s skyline, founded <a data-gid="gid://syiq/Company/3" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Blohm & Voss GmbH (Company)">Blohm &amp; Voss</a> in 1877. They chose the island of Steinwerder to establish what would become a 451,000-square-metre shipbuilding operation – roughly the size of the Vatican City. Initially focused on ship repair, <a data-gid="gid://syiq/Company/3" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Blohm & Voss GmbH (Company)">Blohm &amp; Voss</a> prepared commercial ships for the Atlantic passages before the company started building its own vessels. Today, Steinwerder operates under the custodianship of <a data-gid="gid://syiq/Company/23" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Lürssen Yachts (Company)">Lürssen</a> and has returned to its core principles: refit and repair.Specialising in complex refit programmes for private yachts, <a data-gid="gid://syiq/Company/23" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Lürssen Yachts (Company)">Lürssen</a> Werft Hamburg has maintained Steinwerder’s legacy of being one of the world’s most trusted ports of call for refits. The yard also continues Hamburg’s tradition as a free-flowing hub of maritime knowledge, where expertise is shared across teams, suppliers, and partners.&nbsp;This open-source approach to expertise gives the crew a unique opportunity to learn directly from the wider supply network. When suppliers and technical partners converge in one place, crew gain insight into often-overlooked nuances, ensuring optimal understanding for vessel longevity. Training is regular, problems are solved collaboratively, and the collective intelligence of Hamburg’s maritime ecosystem is fully accessible. The city itself – just a road tunnel away from the shipyard – offers cultural events, international dining, and green spaces along the Elbe, rather than an isolated shipyard town."An effective yacht refit or repair does not necessarily require a shipyard appointment," says York Ilgner, Managing Director of <a data-gid="gid://syiq/Company/23" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Lürssen Yachts (Company)">Lürssen</a> Werft Hamburg. "Smaller details can often be addressed at sea, at anchor, or at layberth with the right knowledge. As part of our service, we aim to impart as much expertise as possible so the crew can operate self-sufficiently. Our phones, of course, remain open when additional support is needed."Informal networks, however valuable, can be fragile when reliant on chance encounters or individual relationships. To address this, <a data-gid="gid://syiq/Company/23" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Lürssen Yachts (Company)">Lürssen</a> has formalised initiatives such as its annual Chief’s Day. The second edition, held recently in Hamburg, brought together more than 80 chief engineers, suppliers, partners, and management teams for a day of technical exchange. From innovations in stabilisation systems to advances in propulsion efficiency, the event brought forward many voices too often absent from strategic conversations. <img src="https://photo-assets.superyachttimes.com/photo/388029/image/large-3c5dccff002b180b0640f9c5554baf40.jpg" data-gid="gid://syiq/Photo/388029">Over the course of the day, one theme surfaced repeatedly: institutional memory. The big question is just how much data should be recorded, and what benefits this brings to ensure seamless maintenance. Which metrics truly predict issues before they escalate? How can maintenance histories transfer between teams without overwhelming them? The difference between a reactive refit and a strategic one often lies in whether previous lessons are learned or lost.Shipbuilding has shaped the identity of Hamburg for more than eight centuries, and <a data-gid="gid://syiq/Company/23" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Lürssen Yachts (Company)">Lürssen</a> sustains its culture of maritime excellence. This culture develops through exchange, one conversation at a time. Hamburg remains what it has always been: a place where ships are built and repaired, and where the knowledge to do both better continues to evolve.
