All ferrous metals are prone to rust, even stainless steel, especially in a marine environment. It can be delayed but not denied completely. If identified promptly and precisely, however, the cost of repairing the damage caused by corrosion can be mitigated.&nbsp;Galvanic, stray current, oxidation, wind borne rust – there are various types of corrosion that afflict metal yachts. Some are easy to spot; others can remain hidden until the vessel undergoes a major refit or special survey. They all cost time and money to remedy. And it’s not just a question of getting rid of unsightly but superficial iron oxide: extensive corrosion, pitting or grooving of load-bearing components can lead to buckling, cracking and other structural defects.<img src="https://photo-assets.superyachttimes.com/photo/315543/image/large-937f72cb3647036d04e307df99cec7ff.jpg" data-gid="gid://syiq/Photo/315543">The traditional method for identifying corrosion is with the naked eye, which usually involves dismantling equipment and stripping off surface treatments to reveal the bare metal underneath. Finding out how deep the corrosion has penetrated then involves bashing away at the steel with a hammer. Ultrasonic corrosion monitoring with high-frequency sound waves is a non-destructive screening method, but metal thickness is measured only at the point where the sensor is placed and surface treatments still have to be removed.Pulsed Eddy Current Array is a non-destructive electromagnetic inspection technology used for measuring metal thickness and detecting corrosion in ferrous materials typically hidden under coatings like teak, fairing compound and fire insulation. The technology allows large areas of metal substrates to be rapidly scanned with multiple probes that can penetrate up to 300mm to provide high-resolution imaging. Using dedicated software, the results are compiled as a plotted corrosion map onto a plan-view of the vessel.<img src="https://photo-assets.superyachttimes.com/photo/315547/image/large-214ca0a9fe800318d7a3398f7171fbc9.jpg" data-gid="gid://syiq/Photo/315547"><a data-gid="gid://syiq/Company/7690" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Brookes Bell (Company)">Brookes Bell</a>With a history stretching back over a century, <a data-gid="gid://syiq/Company/7690" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Brookes Bell (Company)">Brookes Bell</a> is a go-to firm for incident investigation, forensic analysis, technical dispute resolution and expert witness work in the maritime and energy industries. Working closely with the naval and commercial shipping sectors, its PECA analysis process is the only one of its kind formally approved by <a data-gid="gid://syiq/Company/1452" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Lloyd's Register (Company)">Lloyd’s Register</a>. Assisting the company in bringing the same service to the superyacht world is consultant Patrick Yeoward, an MCA 3000t master mariner with over 20 years’ experience of building, refitting and operating large yachts. &nbsp;“A lot of our focus is on the dispute resolution and forensics side and probably 80 percent of the business is commercial shipping,” he says. “But there's a big tie-in with services for superyachts and something we've been looking at over the last few years is how to become more proactive and less reactive by helping to stop things happening, rather than putting a hand up after it happens and say ‘Oh, you shouldn’t have done it like that’.”<img src="https://photo-assets.superyachttimes.com/photo/315546/image/large-0e2ab23c4e9c90c427a8e413f4ec80bf.jpg" data-gid="gid://syiq/Photo/315546">Asset integrity inspection is a time-sensitive activity: owners and their captains need to balance private or commercial use of the yacht with downtime for appropriate repair and maintenance. Because PECA works through insulation and cladding, the scope and frequency of inspections can be ramped up without increasing downtime. Corroded areas can also be identified before a yard period, which allows shipyards to prepare work schedules and order materials in advance. Moreover, knowing the location of generalised corrosion beforehand improves the efficiency of complimentary methods such as radiography and ultrasonic testing that can specifically target these areas. It offers a further advantage when surveying yachts for sale:“Two of my colleagues were just in the south of France to scan a yacht that was being sold,” says Arron Jackaman, principal inspection engineer at <a data-gid="gid://syiq/Company/7690" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Brookes Bell (Company)">Brookes Bell</a>. “Potential buyers want to understand the state of materials and so we performed an inspection and found minor patches of corrosion. We’ve done other inspections where corrosion was suspected, but it transpired the steelwork was in good condition. Either way, it means buyers have a better understanding of the condition of the asset.”<img src="https://photo-assets.superyachttimes.com/photo/315544/image/large-e9a8d1c9d9229f4778e5e47dd7302de7.jpg" data-gid="gid://syiq/Photo/315544">Predictive maintenance&nbsp;<a data-gid="gid://syiq/Company/7690" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Brookes Bell (Company)">Brookes Bell</a> has a contract with the Royal Navy to inspect its Type 23 Frigates to create a baseline or snapshot of material state year on year in areas known to be prone to corrosion. Using its own powerful analytical reporting and modelling software tool called CMAP Marine, the resulting data can be overlaid one on top of the other to create models of how the corrosion progresses over time.“Predictive rather than reactive maintenance is key,” continues Jackaman. “But the complex electromagnetic data gathered from a PECA analysis is only useful or valuable if it can be correctly interpreted. It would certainly be difficult to relate the raw data to the actual vessel without the right visualisation tools. In fact, <a data-gid="gid://syiq/Company/1452" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Lloyd's Register (Company)">Lloyds</a> were very clear that our accreditation is not solely based on the PECA technology, but also on how our CMAP software makes the data easily legible for clients.”<img src="https://photo-assets.superyachttimes.com/photo/315548/image/large-57b1f6721bd0bbf6f95ea4ad5841c850.jpg" data-gid="gid://syiq/Photo/315548">Modelled on <a data-gid="gid://syiq/Company/7690" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Brookes Bell (Company)">Brookes Bell</a>’s 3D data visualisation software, CMAP basically highlights the condition of the remaining steel thickness and material loss in percentage terms. For ease of reference, a colour bar displays sound metal as dark blue and increasing material wastage is indicated as the colours progress through the spectrum to bright red. This provides an intuitive overview of the areas that may require renewal or ongoing monitoring. It doesn't take any special training to understand that red is an issue, but by providing understandable data in a legible format, CMAP allows yacht owners and operators to make better, quicker and more informed decisions.“We’ve spent a number of years honing our own analysis,” adds Jackaman, “because there are several things that can cause signals that look like corrosion but aren't necessarily. Seam welds, internal structures, cable trunking, aluminium scuppers, and many other features, can appear as corrosion. We routinely recognise false positives, which is just as important as identifying corrosion.” <img src="https://photo-assets.superyachttimes.com/photo/315542/image/large-a6d12f1695808a78cf716fc0e332b07a.png" data-gid="gid://syiq/Photo/315542">How PECA worksPulsed eddy current equipment has been successfully applied for the detection and sizing of corrosion under insulation (CUI) for several years. A pulsed eddy current technique uses a stepped or pulsed input signal for greater penetration depth and relative insensibility to variations in coating thickness, or what is termed ‘lift-off’. Unlike ultrasonic thickness testing, no direct surface contact between the probe and the object is necessary.PECA employs multiple elements in a sensory array for much faster scanning times. Intended for the rapid inspection of simple geometries in horizontal and vertical planes such as steel hull, deck and bulkhead plating, it is also suitable for steel pipework that may be encapsulated in fireproofing. Even complex shapes like bends in pipes can be inspected and it can be used in conjunction with other screening techniques if required. <img src="https://photo-assets.superyachttimes.com/photo/315545/image/large-1fda9912a3476b5a49f3c61789f40415.jpg" data-gid="gid://syiq/Photo/315545">The rules prescribing corrosion margins and deviations from the design values vary depending on the type of vessel and the Class Society, but the degree of “allowable material diminution” due to corrosion is generally between 10-30 percent (corrosion rates are expressed in terms of mm per year of surface wastage and are used to provide a corrosion allowance in the original thickness of the material).<ul><li>The areas to be analysed are mapped out into scan zones, either by individual plate sections or broken down into specific zones to tackle the various geometries aboard a vessel.</li><li>PECA probes scan the assigned sections or zone. The resulting data is integrated into a 3D file as a mesh layer to produce a model or digital twin called a CMAP and create a visual representation of the scan, highlighting areas of concern.</li><li>Each plate or zone is also given its own report sheet for further analysis. This provides a clear overview of the condition of each plate or zone, identifying areas that need to be repaired, replaced or carefully monitored. &nbsp;</li></ul>The final stage of the CMAP service involves the creation of a tabular report of each plate or zone. This sets out the physical characteristics of each location, illustrating the average remaining wall thickness, material loss and maximum wall loss values.<img src="https://photo-assets.superyachttimes.com/photo/311269/image/large-31c9223451adf520cb160ea88063b572.jpg" data-gid="gid://syiq/Photo/311269">Case studyIn the recent case of a 50-metre motor yacht scanned during a pre-sale inspection, <a data-gid="gid://syiq/Company/7690" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Brookes Bell (Company)">Brookes Bell</a> analysed the side decks and main deck fore and aft, equating to some 110 square metres, at a cost of around €15,000. Some patches of corrosion were found and 0.6 square metres of steel structure were earmarked for replacement. &nbsp;&nbsp;“When I first spoke with the Captain he was very worried because they’d already had to replace steel about a year-and-a-half ago and were starting to see signs of water ingress,” says Patrick Yeoward. “They were talking about ripping all the teak decking up and starting over again, which would have been massively more expensive in comparison.”<img src="https://photo-assets.superyachttimes.com/photo/311268/image/large-b9e138ad2e12e385e407d4e4a4687637.jpg" data-gid="gid://syiq/Photo/311268">The small area of steel and corresponding teak were eventually replaced by <a data-gid="gid://syiq/Company/5172" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Cantiere Rossini (Company)">Cantiere Rossini</a> in Pesaro, Italy, at a cost of less than €10,000 – a figure that doesn’t compare with the cost &nbsp;of replacing all 110 square metres of teak decking estimated at upwards of €220,000.“Critically, PECA allowed us to limit the scope of work to the deck areas that really needed attention without having to first remove the teak to assess the condition of the steel,” says Alfonso Postorino, shipyard director at <a data-gid="gid://syiq/Company/5172" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Cantiere Rossini (Company)">Cantiere Rossini</a>. “In these cases the precision of the measurement is of the utmost importance - just a few millimetres can make all the difference.”

<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.

By standardising the production process, <a data-gid="gid://syiq/Company/2027" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Castoldi S.p.A. (Company)">Castoldi</a> ensures consistent quality while reducing unit costs through repeated tooling and manufacturing processes. Additionally, serial production provides opportunities for continuous optimisation, further enhancing the performance and quality of each new upgraded model.

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.

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;

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.

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.

This accelerates the development of new prefab applications and makes us faster, sharper and more creative in what we can offer our clients.Boteka has been a trusted partner of ours in the cruise ship sector for more than 14 years.

By bringing Boteka fully into the <a data-gid="gid://syiq/Company/7672" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Bolidt (Company)">Bolidt</a> organisation, we can keep everything we produce under one roof.

Compared to the scale of some of the cruise ship decking we’ve worked on, <a data-gid="gid://syiq/Yacht/10354" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Leviathan111.0m (364'2&quot;)Oceanco2025">Leviathan</a> is actually quite small. 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.

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.

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.

How To Build It - Issue 10: Technology, tradition and transformation in the superyacht industry

Twenty-odd years ago, the super-sailing sector began setting benchmarks using advanced composites to build sophisticated skyscraper rigs. With several significant sailing projects now in build, we look into what has changed in mast design and construction, and what the future may hold for super-sized spars.As the super sailing yacht fleet has grown, both in number and in size, so the engineering demands have increased – particularly when it comes to the mast. Extreme LOAs have led to extreme spars, spurred by developments in materials science both for the mast tubes themselves as carbon has evolved to serve as an alternative to aluminium, and in the rigging that supports them.Owners’ desires to push boundaries has delivered compelling sailing projects through the years, perhaps best embodied by yachts like <a data-gid="gid://syiq/Yacht/301" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="M577.6m (254'7&quot;)Vosper Thornycroft2004">M5</a> (ex-<a data-gid="gid://syiq/Yacht/301" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="M577.6m (254'7&quot;)Vosper Thornycroft2004">Mirabella 5</a>) with her towering 88-metre sloop rig; the “sail-assisted” Sailing Yacht A, whose freestanding carbon masts are the biggest built to date; and, of course, <a data-gid="gid://syiq/Yacht/385" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Maltese Falcon88.0m (288'9&quot;)Perini Navi2006">Maltese Falcon</a> with her revolutionary DynaRig. That they still stand as remarkable and record-breaking speaks volumes, and it’s only with recent projects such as <a data-gid="gid://syiq/Yacht/4795" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Black Pearl106.7m (350'1&quot;)Oceanco2018">Black Pearl</a> or the under-construction 85m Sloop&nbsp;<a data-gid="gid://syiq/Yacht/12001" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Royal Huisman 85m Sloop84.9m (278'7&quot;)Royal Huisman2026">Project 410</a> at <a data-gid="gid://syiq/Company/122" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Royal Huisman (Company)">Royal Huisman</a>, for example, that they are being challenged in size and scope.<img src="https://photo-assets.superyachttimes.com/photo/382854/image/large-dc488e35687534ee098a60a520afbc83.jpg" data-gid="gid://syiq/Photo/382854">“When we designed <a data-gid="gid://syiq/Yacht/301" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="M577.6m (254'7&quot;)Vosper Thornycroft2004">M5</a> nearly 25 years ago we didn’t realise how close to the bone we were,” begins Rob Doyle, Principal of the <a data-gid="gid://syiq/Company/3009" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Rob Doyle Design (Company)">Rob Doyle Design studio</a> who previously worked under sailing yacht supremo <a data-gid="gid://syiq/Company/52" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Ron Holland Design (Company)">Ron Holland</a>. “It was designed according to the maximum length of Nitronic 50 rod rigging available at the time, which I think was 76mm in diameter. It all came down to the suaging at the top and the length of the bar. We went for a five-spreader rig that came out at 88 metres, and said that’s how big it should be – let’s see how much keel we need to put underneath it.”Doyle recalls the mast was essentially sketched in an afternoon with the team using the known limitations of the materials as the starting point.&nbsp;“There was no book you could open, no expert you could call on – it was a real moonshot project,” he says. “It has taken 20 years for anyone to take on something similar with the new 80-metre yachts in build. And even then they will only beat her by a couple of metres.”<img src="https://photo-assets.superyachttimes.com/photo/382860/image/large-a888ed29dd9fc3ec24b2caa900aef519.jpg" data-gid="gid://syiq/Photo/382860">Why Would You?&nbsp;For Doyle, times have changed in big rig design, with an emphasis on practicality rather than pushing materials to the limits: “The relevant question now is not how you would tackle such a project, it’s why? You can’t get under Panama, you can’t fly a spinnaker, you need an army of people just to get a sail up and down, and there’s a lot of heavy engineering required to handle half a football pitch of sail with a couple of sheets.”It is here that innovations such as the DynaRig stepped in. Developed by <a data-gid="gid://syiq/Company/230" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Dykstra Naval Architects (Company)">Dykstra Naval Architects</a> based on an original 1960s concept, the freestanding, square-rigger-inspired spars and sail plan showed how super-sized sailing yachts could fly large areas of sail without requiring enormous crews. The concept arguably became a victim of its own fame as few owners wanted to be seen copying an iconic design. But the rig did eventually find its way onto a new project in <a data-gid="gid://syiq/Yacht/4795" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Black Pearl106.7m (350'1&quot;)Oceanco2018">Black Pearl</a>, and will subsequently feature on the 58-metre Adventure Sailing Cat multihull project, <a data-gid="gid://syiq/Yacht/13716" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Charley 358.63m (192'4&quot;)Echo Yachts2028">Charley 3</a>, in build at <a data-gid="gid://syiq/Company/4342" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Echo Yachts (Company)">Echo Yachts</a>.<img src="https://photo-assets.superyachttimes.com/photo/382853/image/large-d0ecfa8b48f4825631d42583df4a26f6.jpg" data-gid="gid://syiq/Photo/382853">While mast construction technology is largely settled, that doesn’t mean that pioneers aren’t still pushing boundaries – just not in ways you might expect. Spanish engineer Juan Sarmiento, for example, has proposed and patented a system that uses the oscillation of a mast to generate power.For the sailing yacht Zero project, meanwhile, the team have opted for a mast design that will use the principles of stack ventilation to deliver energy-neutral air circulation for the yacht’s interior. For a project that will operate without carrying a drop of fossil fuel, such solutions are an integral part of the goal to minimise energy use on board, but they also speak to the potential of spars to serve a dual purpose for no cost in performance of the vessel.Zero’s main and mizzen are being built by Carbo-Link, a company with extensive experience in the civil engineering and aerospace sectors, and which has been developing and supplying rigging solutions to race boats and superyachts since it was brought in to develop the rigging for the first Alinghi America’s Cup challenge back in 2001. The Zero project, however, marks its first foray into mast-building, serving effectively to launch a new business division for the Swiss company.“The marine industry moves fast, and people are happy to try new technologies – more so than in our other sectors, which tend to be more risk-averse,” says James Wilkinson, Sales &amp; Strategy Director at Carbo-Link. “We started on the Zero project a couple of years ago having got to know the people behind it through supplying rigging to another yacht, and that led to the birth of our mast business that we formally launched in June 2025.”<img src="https://photo-assets.superyachttimes.com/photo/382859/image/large-9d70f02c5df0d7c7a5dccff5897a9173.png" data-gid="gid://syiq/Photo/382859">Out of the Ordinary&nbsp;For a first-time mast build, Zero’s spars are far from straightforward. While the Panamax ketch rig is not groundbreaking in itself, the idea of using the mast to ventilate the interior added levels of complexity to the design of the mast section.&nbsp;“From the start it was clear it was not going to be run-of-the-mill,” Wilkinson says. “There were a lot of ideas discussed between the Zero team, our heads of department and our founder, Dr Andy Winistoerfer, who is the lead materials scientist here.”Through 3D modelling and FEA, the team explored several options that included not only adiabatic cooling (a process where air temperature decreases due to expansion, without any heat exchange with the surroundings), but also flexible solar panels on the masts, as well as different lightning protection methods.&nbsp;The adiabatic cooling works on the basis of stack ventilation – hot air rises, and in the mast column itself is further heated by the sun on the mast to encourage faster vertical airflow, with the hot air exiting at the top of the mast. This creates the opportunity via a system at the base of the mast for free air circulation for the yacht’s interior, reducing energy demand for the air circulation and air-con systems. The outside shape of the masts is fairly traditional, save for some optimisation of the shape based on Carbo-Link’s production processes. <img src="https://photo-assets.superyachttimes.com/photo/382852/image/large-f7b9ad9ad5beb7f6983426ad1b1180ab.jpg" data-gid="gid://syiq/Photo/382852">“We’ve gone slightly larger in section to ensure stiffness with a thinner mast wall and we actually ended up with a lighter solution overall,” Wilkinson explains. “That larger section also means more internal space, and by using longitudinal stringers we don’t have a lot of bulkheads in the mast, meaning the only things going across the mast section are the tangs.”The cabling, wiring and other conduits in the mast have been integrated into the stringers to create a very clean internal structure with lots of space for air flow, with just the halyards running internally separate to the stringer-conduits. Also the top of the mast is actually open, with what are effectively two lungs.&nbsp;The masts will be built and cured in one piece, which also ensures a very clean construction, which further maximises internal space. Interestingly, although the team decided not to apply solar panels to the masts, Carbo-Link has included space in the internal conduits to allow for the required cabling, plus future-proofing by designing in areas for mast cut-outs and for mounting of tech such as LiDAR, CCTV or Starlink antennas on the spreaders.<img src="https://photo-assets.superyachttimes.com/photo/382849/image/large-08f4100a512d226a0866e2ef8c62f544.jpg" data-gid="gid://syiq/Photo/382849">Beyond ZeroZero’s masts threw up another first: “This is the first sailing yacht to have the full Lloyd’s notation as a certification requirement, because it’s the only yacht which is sail-driven and motor-assisted,” Wilkinson points out. “That means we’ve had to certify the source and quality of all materials, show the detailed engineering of the design, and prove all our processes.”Beyond Zero, Carbo-Link is looking at how it can help encourage the super-sailing sector by reducing the cost of build, and that means reducing the cost of spars and sailing systems.&nbsp;“We are looking to invest quite heavily in automating a lot of our processes to reduce costs,” says Wilkinson. “With our one-piece production processes, for example, there’s a lot more optimised use of the materials and fibres in the way we’re building the mast, using less for the same stiffness and strength. Our ambition is to is to be able to supply highly complex, highly reliable, highly optimised solutions, but at a reasonable price point – and that's purely to help drive the sailing industry.”This article was first published in <a href="https://www.superyachttimes.com/magazine/how-to-build-it-issue-9-download" target="_blank">issue 9 of How To Build It</a>.

Spars and appendages: The evolution of mast design and construction

The Chinese State Council has approved new measures that will reduce administrative and financial barriers for Hong Kong and Macau yacht owners travelling within the Guangdong-Hong Kong-Macao Greater Bay Area (GBA).<img src="https://photo-assets.superyachttimes.com/photo/284352/image/large-ecd218fffb9bcb7bafecade7dd2c5004.jpg" data-gid="gid://syiq/Photo/284352">Announced on 30 May 2026, the new policies will remove the requirement for a financial guarantee and introduce a temporary Chinese registration when bringing their yacht into mainland China.Under the new framework, Hong Kong and Macau-registered yachts will be able to obtain temporary ship nationality certificates issued by mainland Chinese authorities without affecting their existing registrations.&nbsp;This will allow yachts to navigate within the waters of nine mainland cities in the Greater Bay Area after completing the necessary entry procedures. “Guangdong, Hong Kong and Macao have been committed to promoting individual yacht travel,” explained a spokesman for the Transport and Logistics Bureau.“Under the new policy, the exemption for the requirement for a guarantee will significantly reduce the financial burden on owners of Hong Kong and Macao yachts when handling cross-border procedures.”<img src="https://photo-assets.superyachttimes.com/photo/380444/image/large-c47ce0baf12facf7f4f5bd21055eb53c.jpg" data-gid="gid://syiq/Photo/380444">To support these efforts, the Hong Kong Marine Department, the Guangdong Maritime Safety Administration and the Macau Marine and Water Bureau established a tripartite working group focused on developing measures to facilitate private yacht movements across the region.The Marine Department is also actively co-ordinating with the Guangdong Maritime Safety Administration on creating southbound measures for yachts travelling from the Chinese Mainland, with details due to be announced soon following finalisation.&nbsp;In March 2025, lawmakers in Hong Kong urged the government to enhance yacht tourism in the Greater Bay Area (GBA) and further develop the necessary infrastructure to support maritime activities.A motion was proposed by Kenneth Lau Ip-keung advocating for improved infrastructure to facilitate island-hopping tourism ventures along Hong Kong’s 1,180-kilometre coastline and its 263 islands.&nbsp;Read more:&nbsp;<a data-gid="gid://syiq/Article/62956" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Lawmakers urge Hong Kong government to boost yacht tourism (2025-03-26 12:30:00 +0100)">Lawmakers urge Hong Kong government to boost yacht tourism</a> <img src="https://photo-assets.superyachttimes.com/photo/395562/image/large-12835460c889137d51c1912c58b38d42.png" data-gid="gid://syiq/Photo/395562">Asia-Pacific Superyacht SummitAs the region continues to grow, SuperYacht Times has hosted several editions of the <a data-gid="gid://syiq/Article/66230" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Asia-Pacific Superyacht Summit Japan 2026 in 60 seconds (2026-06-02 15:00:00 +0200)">Asia-Pacific Superyacht Summit</a> in Hong Kong.
