Travelling to Sydney, Leona Caanen speaks with Luke Geelan, family man and owner of the&nbsp;<a data-gid="gid://syiq/Yacht/3832" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Shore Thing35.05m (114'12&quot;)Lloyds Ships1986">Shore Thing</a>&nbsp;fleet.Growing up with a passion for boating, and especially fishing, is Luke Geelan, Sydney native and owner of the 35.05-metre motor yacht <a data-gid="gid://syiq/Yacht/3832" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Shore Thing35.05m (114'12&quot;)Lloyds Ships1986">Shore Thing</a>. Having spent most of his life around the water, it seems only natural for Luke to have moved into the world of boating. Overtime the yacht has come to resemble not only a connection to his past, but also to his future, getting to enjoy it with his family and friends, as well as sharing it with charter guests.<img src="https://photo-assets.superyachttimes.com/photo/388213/image/large-0b83e89d1054e69437b37ff303a35921.jpg" data-gid="gid://syiq/Photo/388213">A family passionGrowing up on a river in Sydney, Luke was introduced to the rhythms of tide and weather from an early age. “I’ve grown up with a passion for boating, my father taught me to water ski and sail as a young child” Luke shares. Over time, Luke exchanged sailing for wakeboarding and eventually game-fishing, depending his passion for being out at sea. This passion has remained a constant factor in Luke’s life, deepening even further once he could share it with his own kids.A few years ago, Luke sold his business and decided to step into boating in a more deliberate way by acquiring the 35-metre motor yacht <a data-gid="gid://syiq/Yacht/3832" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Shore Thing35.05m (114'12&quot;)Lloyds Ships1986">Shore Thing</a>, built by <a data-gid="gid://syiq/Company/554" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Lloyds Ships (Company)">Lloyd Ships</a> in Australia in 1986. Purchasing her in 2024, the yacht allowed for Luke and his family to explore the Australian coast with more comfort, as well as for them to get to share their passion for the sea. “My two boys are especially big on game fishing, and my daughter is very passionate about snorkelling and marine life”, says Luke. By acquiring <a data-gid="gid://syiq/Yacht/3832" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Shore Thing35.05m (114'12&quot;)Lloyds Ships1986">Shore Thing</a>, it allows for the family to share their passions with one another.<img src="https://photo-assets.superyachttimes.com/photo/396937/image/large-131bb2f788c31defa0822382f533d318.jpg" data-gid="gid://syiq/Photo/396937">A three-part refitAs <a data-gid="gid://syiq/Yacht/3832" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Shore Thing35.05m (114'12&quot;)Lloyds Ships1986">Shore Thing</a> is from the 80s, she was in need of an upgrade when Luke purchased her. The refit has been phased and purposeful, with 2024 seeing the first of the three phases. The yacht spent September to November at the <a data-gid="gid://syiq/Company/3255" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Gold Coast City Marina & Shipyard (Company)">Gold Coast City Marina &amp; Shipyard</a> where the bridge was upgraded, soft furnishings replaced and extensive paintwork completed. <img src="https://photo-assets.superyachttimes.com/photo/388209/image/large-c74eb7958e3e321e611bea0e2d9fee9c.jpg" data-gid="gid://syiq/Photo/388209">The second phase was centred around remodelling the saloon, with new flooring, carpeting and ceilings, as well as mechanical enhancements. Other upgrades included a beach club installation, complete with an inflatable pool, protective netting and a shaded cabana, which has proved particularly popular with charter guests. Possibly the most meaningful addition during this refit have been the zero-speed stabilisers, “my wife suffers from really severe seasickness, the stabilisers are essential in making the yacht comfortable for my family,” Luke shares.<img src="https://photo-assets.superyachttimes.com/photo/388210/image/large-06ec6524534531dc1f3ac942dd743803.jpg" data-gid="gid://syiq/Photo/388210"><a data-gid="gid://syiq/Yacht/3832" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Shore Thing35.05m (114'12&quot;)Lloyds Ships1986">Shore Thing</a>’s third and final refit will take place in 2027 and will see an upgrade of the crew quarters. Originally, Luke had hoped to finalise the refit this year, but the yacht’s agenda, both in charter and personal use, is almost fully booked for the calendar year, and Luke wants to ensure there is enough time for the refit: “Our crew is so amazing, I'm super lucky to have what I believe is the best crew.<img src="https://photo-assets.superyachttimes.com/photo/388187/image/large-fde4622fb25e3e416358ace496ed0104.jpg" data-gid="gid://syiq/Photo/388187"><a data-gid="gid://syiq/Yacht/3832" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Shore Thing35.05m (114'12&quot;)Lloyds Ships1986">Shore Thing</a>&nbsp;juniorYet the 35-metre motor yacht is only half the story. Six months after acquiring the mothership, Luke secured what he describes as Australia’s leading game fishing platform: a custom-built 17.7-metre (58’0”) Assegai sportfisher. Designed specifically for marlin fishing along the country’s east coast, the yacht is equipped with a gyro stabiliser and, more recently, a Furuno Omni Sonar System capable of scanning 360 degrees around the vessel to significant depths, providing a technological edge in a pursuit that still relies on instinct and patience.<img src="https://photo-assets.superyachttimes.com/photo/396954/image/large-96857bf8151cfcd655d86dc3d061d704.png" data-gid="gid://syiq/Photo/396954">The reason for acquiring the fishing vessel to cruise alongside the mothership are his sons. Luke shares that “my sons and I have been game fishing together for the last five years or so,” and have even partaken in various competitions in- and around Sydney. “We’ve won a couple of state titles and other competitions,” a hint of pride sits in Luke’s voice. “My children in particular, have a passion for fishing, and I've just shared that passion, and supported it”, he adds.Lukes really enjoys fishing with his family and friends, on a recent trip to the Great Barrier Reef, the Shore Thing 58' landed a 1,223 pound Black Marlin. Yet Luke is quick to note that they’re conscious about the way they fish. “We only catch what we eat; everything else goes right back in the ocean. We’re not hunters, we just fish for the joy of it.”<img src="https://photo-assets.superyachttimes.com/photo/388186/image/large-a98a34adf0095495d9e5f32f36eb458e.jpg" data-gid="gid://syiq/Photo/388186">The joy of cruisingSome of Luke’s most cherished moments onboard are those with friends and family. “We hosted my 50th birthday onboard,” Luke shares, having chartered the yacht to Whitehaven Beach, located in the Whitsundays, “there were about 40 guests, all friends and family.”&nbsp;Possibly Luke’s favourite memory is the recent Christmas holiday onboard. “Spending time with our family and another family, sitting around and just having deep belly laughs over some beautifully cooked meals by our chef onboard.” Luke describes this as delightful and quite possibly one of the most memorable times onboard. “Your kids grow up so quick, getting to share such a beautiful time together and feeling like, as your kids become young adults, that you can really share laughs and stories. It was just special.”<img src="https://photo-assets.superyachttimes.com/photo/396938/image/large-04bc34860fd9bc9b421321a8d9f42e09.jpg" data-gid="gid://syiq/Photo/396938">The beauty of being on a boat is that it ties everyone together, whether that is his own family and friends, or guests who charter the yacht, for Luke, the joy of owning <a data-gid="gid://syiq/Yacht/3832" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Shore Thing35.05m (114'12&quot;)Lloyds Ships1986">Shore Thing</a> lies in “getting to share the joy with other people.”The yacht and her fishing counterpart offer not just a sense of luxury, but a space for guests to create memories and experience the beauty of the Australian coastline as they cruise <a data-gid="gid://syiq/Yacht/3832" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Shore Thing35.05m (114'12&quot;)Lloyds Ships1986">Shore Thing</a> between the Great Barrier Reef, the Whitsundays and the Sydney Harbour.<img src="https://photo-assets.superyachttimes.com/photo/388177/image/large-2991a957e2fdb4ef0038789921600aa2.jpg" data-gid="gid://syiq/Photo/388177">

<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. Developed in response to a request to optimise the passage from the main deck to the beach platform on <a data-gid="gid://syiq/Company/29" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Feadship (Company)">Feadship’s</a> 79.5-metre <a data-gid="gid://syiq/Yacht/11677" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Valor79.5m (260'10&quot;)Feadship2025">Valor</a>, <a data-gid="gid://syiq/Company/5438" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Akerboom Yacht Equipment (Company)">Akerboom</a>’s engineers merged door, hatch and boarding equipment components to create a completely new solution. 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. Before delivery, full functional testing is carried out in-house, often with owner representatives present.Enclosed helicopter lifts represent some of the most complex control systems <a data-gid="gid://syiq/Company/5438" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Akerboom Yacht Equipment (Company)">Akerboom</a> has delivered.

Ironically, real-world usage of helicopter lifts has revealed an interesting pattern:&nbsp;<img src="https://photo-assets.superyachttimes.com/photo/396746/image/large-793a08021cda2fc7bab19c3cd8f1a821.jpeg" data-gid="gid://syiq/Photo/396746">“On some yachts, the heli hangars are no longer actively used and instead function as static storage platforms,” reveals van der Ploeg. “In such cases, owners may even suspend servicing altogether – an illustration of how operational reality can diverge from original design intent.”Developments in control systems are being matched by advances in data intelligence. 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>.

As contemporary superyacht design continues to prioritise light, openness and seamless connections to the sea, glass has evolved from a purely functional element into a defining aesthetic feature and, with the use of significantly larger glass panels, has become an essential structural component. Expansive glazing now shapes not only the visual identity of a yacht but also its engineering framework, requiring a far more integrated and technically rigorous approach.For German specialist <a data-gid="gid://syiq/Company/3829" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="TILSE Glass (Company)">TILSE</a>, this shift represents both an opportunity and a responsibility – to ensure that increasingly ambitious designs are matched by uncompromising structural integrity, durability and precision.<img src="https://photo-assets.superyachttimes.com/photo/293944/image/large-ecdb75ea245212d313561b3fadf7f87c.jpg" data-gid="gid://syiq/Photo/293944">Integrating glass from the concept stageLarger glass surfaces have fundamentally changed how glazing is approached in yacht construction. No longer a late-stage addition, glass must be embedded into the superstructure concept from the earliest design phases, with engineers analysing how forces move through the pane, adhesive bond and surrounding structure.Unlike static architectural environments, yachts operate under continuous dynamic loads, with hull flex, vibration and thermal variation all influencing performance. Safety margins must therefore reflect real marine conditions, while thickness, laminate composition, bonding strategy, edge detailing and installation methodology all need to be considered from the outset.Early collaboration is essential. By working with designers and naval architects at the concept stage, <a data-gid="gid://syiq/Company/3829" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="TILSE Glass (Company)">TILSE</a> helps ensure that visual ambitions are achievable without compromising technical feasibility, long-term serviceability or structural integrity. This proactive approach allows glazing to do more than fit within a design – it helps shape the structural logic of the vessel, balancing elegance with engineering robustness.<img src="https://photo-assets.superyachttimes.com/photo/286853/image/large-74c88213b1c3eba82cf06fc659c13e71.jpg" data-gid="gid://syiq/Photo/286853">Bonding as a safety-critical interfaceOne of the most significant technical challenges is bonding glass – which is inherently brittle – to aluminium or steel structures that move, flex and expand differently under load and temperature change. The adhesive joint must do more than hold the panel in place: it must accommodate movement, transfer loads safely and maintain integrity under UV exposure, salt, humidity and vibration.“The real challenge is not only the glass pane itself, but the interface between glass and a structure that is constantly moving at sea.”As panel sizes increase, this interface becomes even more critical, since minor mismatches in movement, geometry or application can have amplified consequences. Bond thickness, surface preparation, laminate compatibility and UV protection must therefore be precisely controlled. In superyacht glazing, adhesive design is not a detail – it is part of the safety concept, and a well-engineered bond line underpins both structural integrity and long-term durability.Simulation and real-world performanceFinite Element analysis helps validate glass performance, particularly in complex or non-standard applications, by modelling the interaction between glass, adhesive and supporting structure under realistic marine loads. This allows engineers to identify stress points, optimise designs and support conditions, and mitigate deflection risks early in the project lifecycle.Unlike building façades, yacht structures are subject to continuous movement, making accurate modelling essential. Long-term factors such as moisture ingress, ageing and laminate degradation must also be assessed, as they can directly affect load-bearing capacity.As glass panels grow in size, tolerances become increasingly critical. Millimetre-level deviations in shaping or installation can influence load distribution and compromise both structural performance and visual alignment. Handling and installation of large panes have therefore become technical operations in their own right, requiring precise three-dimensional measurement and meticulous execution.<img src="https://photo-assets.superyachttimes.com/photo/333152/image/large-73662ca86854e3909e622abf8863c6a4.jpg" data-gid="gid://syiq/Photo/333152">Ensuring long-term laminate integrityLong-term durability begins with material selection. Because traditional PVB interlayers, which are widely used, can be vulnerable to humidity and temperature fluctuations, <a data-gid="gid://syiq/Company/3829" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="TILSE Glass (Company)">TILSE</a> uses a specially developed resin interlayer designed for enhanced moisture resistance at sea, thereby preventing delamination.Chemical toughening further improves optical clarity, reduces distortion and avoids the anisotropy often associated with thermally toughened glass. Strict quality control from raw material selection to lamination, sealing and final inspection ensures each pane meets superyacht standards.Consistency in bespoke productionFor bespoke glazing, consistency depends on rigorous process control across the entire project chain, from early consultation and three-dimensional measurement through to production and installation. <a data-gid="gid://syiq/Company/3829" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="TILSE Glass (Company)">TILSE</a>’s integrated approach reduces variability and ensures consistency across the entire project chain, even when each pane is uniquely specified.Combined with stringent inspection protocols and a commitment to rejecting substandard components, this enables the delivery of reliable, high-performance glazing systems.Engineering next-generation glazingLooking ahead, the trajectory of superyacht design points towards even larger, clearer and more seamlessly integrated glass surfaces. However, the next phase of innovation will be defined not by scale alone, but by the ability to balance ambition with practicality. Manufacturability, optical quality, structural safety, durability and ease of replacement will all play an increasingly important role in shaping future designs.As glass cements its position as a defining element of modern yacht design, its successful application depends on far more than aesthetics. Structural integration, bonding expertise, advanced simulation and uncompromising material quality must come together from the very beginning.In response, <a data-gid="gid://syiq/Company/3829" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="TILSE Glass (Company)">TILSE</a> continues to invest in expanded production capacity, advanced handling capabilities and earlier involvement in complex projects – helping today’s most ambitious glazing concepts to be realised safely, durably and with the clarity expected of the next generation of superyachts.
