AB Yacht Design & Naval Architecture

Co-founded in 2022 by entrepreneur Yiannis Andriotis and a longtime friend, <a data-gid="gid://syiq/Company/6958" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Leapher Shipbuilding BV (Company)">Leapher Yachts</a> has positioned itself firmly within the explorer segment, focusing on capability, autonomy and long-term liveability. Based at the De Hoop shipyard in Tolkamer, the Netherlands, the company is preparing to launch its first vessel later this year, the 60.96-metre Navix60.SuperYacht Times spoke with Yiannis Andriotis about the philosophy underpinning <a data-gid="gid://syiq/Company/6958" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Leapher Shipbuilding BV (Company)">Leapher Yachts</a>, its construction approach, and the thinking behind its focus on the 50 to 82-metre category. The conversation also explored what differentiates the brand, the details of the Navix60 currently under construction, and the shipyard’s upcoming developments.<img src="https://photo-assets.superyachttimes.com/photo/334497/image/large-5e4754b7e15b2568d97f046d87293423.jpg" data-gid="gid://syiq/Photo/334497">Philosophy and construction approach “<a data-gid="gid://syiq/Company/6958" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Leapher Shipbuilding BV (Company)">Leapher</a> explorers are all about expanding lifestyle limits. We have a strong design mentality that mixes the attributes of different yacht types into a platform that outperforms current industry standards,” commented Andriotis, reflecting on the philosophy behind <a data-gid="gid://syiq/Company/6958" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Leapher Shipbuilding BV (Company)">Leapher</a>.<a data-gid="gid://syiq/Company/6958" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Leapher Shipbuilding BV (Company)">Leapher</a> offers a portfolio of explorer yachts ranging from 50 to 82 metres, each conceived to deliver long-range capability, technical resilience and a high degree of comfort for extended living at sea.“The idea is to bring in more volume for the same length compared to other boats, and this is basically the key,” says Andriotis. “We offer bigger boats for the same length, more volume and more gross tonnage for less cost compared to the competition, because for us volume reduces the cost of construction.”<img src="https://photo-assets.superyachttimes.com/photo/371517/image/large-63f45384e4eae040427506523acbd4f1.jpg" data-gid="gid://syiq/Photo/371517">Andriotis explains that the choice of size range is deliberate. “We focus on the 50 to 82-metre range because we believe owners seek maximum capability within this size. For us, a ‘capable yacht’ means a vessel designed for true global exploration: it should have long-range cruising ability, robust autonomy, high comfort for extended living at sea, and advanced navigation and safety systems that allow confident travel to remote destinations.”He adds that yachts above 85-metres often prioritise sheer scale over agility and autonomy, while those below 50-metres tend to lack the volume and range required for genuine worldwide cruising. “This is why we dedicate our expertise to the 50 to 82-metre category, where our values and innovation can truly shine.”Each model within the Navix Series benefits from the lessons learned across the range. Larger yachts draw on outfitting methods pioneered on smaller volumes, while more compact models adopt the same core mechanical systems as their bigger siblings. In this way, <a data-gid="gid://syiq/Company/6958" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Leapher Shipbuilding BV (Company)">Leapher</a> seeks to ensure consistency in capability and philosophy, regardless of size.<img src="https://photo-assets.superyachttimes.com/photo/309863/image/large-35b3f7704bf884154e4e5cf392d996e1.jpg" data-gid="gid://syiq/Photo/309863">The Navix60 under constructionCurrently in build at the De Hoop shipyard, the 61-metre Navix60 has been conceived as one of the most capable yachts in her class. With a beam of 12.8 metres and a volume of 1,750 gross tons, almost 700 gross tons above the norm for yachts of comparable length, she places a strong emphasis on interior space and comfort. Her exterior and interior design are by Cor D. Rover Design, while naval architecture is the work of O7 Designers and Van Oossanen Naval Architects.“Autonomy is central to the Navix60’s design philosophy,” explains Andriotis. The yacht features a double hull constructed to Ice Class and Polar Code standards, enabling her to navigate safely across a wide range of destinations. With a range of 9,000 nautical miles at a cruising speed of 10 knots, she is designed to remain at sea for up to 40 days, including in low emission and zero discharge zones. According to Andriotis, this extended autonomy means “owners and guests can undertake ambitious voyages, from crossing oceans to exploring the polar regions, without concern for frequent resupply or environmental impact.”<img src="https://photo-assets.superyachttimes.com/photo/371510/image/large-a9d29b7bbbd7f4a9bb8cf5bdd1eb2f16.jpg" data-gid="gid://syiq/Photo/371510">Adaptability is another defining element. A multifunctional expedition store has been designed to transform depending on the nature of each voyage: it might be used as a classroom, a research facility, specialist storage for equipment, or simply as a playroom for family guests. A similar approach is evident in the onboard hospital, which can be reconfigured as a guest suite if extra accommodation is needed. “This flexibility is invaluable during long expeditions, where the needs and interests of guests can change frequently,” notes Andriotis. “Maximising available space ensures every journey is tailored to its participants.”<img src="https://photo-assets.superyachttimes.com/photo/371511/image/large-84d9a61d600ddd81d7cd1c7ae076ae97.jpg" data-gid="gid://syiq/Photo/371511">The Navix60 also accommodates a variety of operational requirements. Owners may, for instance, rely on helicopter transport when attending an event in Monaco, but switch to a seaplane for a passage from South Georgia to the Weddell Sea.<img src="https://photo-assets.superyachttimes.com/photo/309859/image/large-e7008c3201fc9b81c3b5f883e37c967b.jpg" data-gid="gid://syiq/Photo/309859">Technological resilience underpins this versatility. The yacht is equipped with systems drawn from both military and commercial sectors, with layered redundancies across navigation, communication and power supply. For Andriotis, this robustness is key: “It allows both crew and guests to focus on what truly matters, the journey itself, secure in the knowledge that safety, comfort and performance are never in question.”Reflecting on the design process, Andriotis adds: “To achieve this, we had to bring together all of our capabilities and push the limits of the team’s creativity and problem-solving skills. It was a wonderful experience to see <a data-gid="gid://syiq/Company/43" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Cor D. Rover Design (Company)">Cor D. Rover</a> translate our vision into a design that is both unique and range-defining. It is always a challenge to fit 1,800 gross tons into an elegant, proportionally balanced and timeless profile.”The Navix60 is scheduled to launch at the end of the year.Future plans and developments <img src="https://photo-assets.superyachttimes.com/photo/371515/image/large-a484f1211d6ff0c5f92e6e2455972df3.png" data-gid="gid://syiq/Photo/371515">Looking ahead, <a data-gid="gid://syiq/Company/6958" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="Leapher Shipbuilding BV (Company)">Leapher Yachts</a> is preparing for a significant milestone with the launch and delivery of its first Navix60. “This year has been both productive and important for us,” says Andriotis. “The first Navix60 is nearing its launch, and we are preparing for its delivery to the client. The results so far have been outstanding and reflect the hard work of our entire team. This milestone allows us to showcase to the world what we are capable of achieving, setting a new standard for our shipyard.”Alongside this, the shipyard has confirmed the addition of a new model, the Navix55, developed in collaboration with <a data-gid="gid://syiq/Company/6299" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="AB Yacht Design & Naval Architecture (Company)">AB Yacht Design</a>. Designed as a world cruiser, the Navix55 offers an extended tender carrying capacity, a seven-cabin layout, and ample storage. Features such as a spacious semi-open beach club, a helipad that can double as a basketball court, a dedicated gym and wellness area, and advanced soundproofing introduce amenities more commonly found on significantly larger yachts.Customisation will also be central to the model, with a wide variety of interior configurations, materials and technologies available. According to Andriotis, “our streamlined build process also means reduced delivery times compared to industry norms.”<img src="https://photo-assets.superyachttimes.com/photo/371541/image/large-5d394326bb8ea7377bed422b5f0af7b5.png" data-gid="gid://syiq/Photo/371541">The Navix55 reinforces the broader Navix philosophy of adaptability and multifunctional use. Flexible interior spaces allow for conversion between research, family or guest purposes, while open connections between saloon and aft deck enhance the sense of continuity between interior and exterior living. “The main design feature is this adaptability,” concludes Andriotis, “combined with top-tier engineering and a commitment to delivering a yacht that owners can trust for adventures anywhere in the world.”Positioned between the Navix50 and Navix60, the Navix55 is designed to bridge the gap between the two models. It offers a wide array of onboard amenities without being constrained by the sub-500 gross ton threshold. While the Navix50 remains the ideal solution for owners seeking a compact explorer under 500 gross tons, the Navix55 expands the offering with increased volume, flexibility and features, while staying true to the core principles that define the Navix range.<img src="https://photo-assets.superyachttimes.com/photo/371516/image/large-4bc75b2537554996b89971b41bde5c2f.png" data-gid="gid://syiq/Photo/371516">

Leapher Yachts unveils new NAVIX50 explorer yacht concept

The past few years have seen a wave of large scale sportfisher superyachts, and demand for the traditionally American yachts has reached an all-time high across the industry. <a data-gid="gid://syiq/Company/6299" href="#managed-by-system" rel="noopener noreferrer" target="_blank" title="AB Yacht Design & Naval Architecture (Company)">AB Yacht Design</a> studio, the British studio under designer Aristotelis Betsis, has now unveiled a 60-metre sportfisher superyacht concept called Project Canyon. <img src="https://photo-assets.superyachttimes.com/photo/250635/image/large-fa8c5dfa9beff302caf9a7c4cbdc49f0.png" data-gid="gid://syiq/Photo/250635">The yacht combines the utilitarian and adventure focused nature of sportfishers, with the luxury of a superyacht. The exterior design is characterised by smooth lines and a modern aesthetic, with the tower fitting seamlessly into the overall design rather than dominating it.<img src="https://photo-assets.superyachttimes.com/photo/250636/image/large-3586d9c869a031fccc161f46a4cf578c.png" data-gid="gid://syiq/Photo/250636">“We always try to invest time in the development of concepts.

A 12 metre shadow boat can be stowed in this area when underway using a twin-cradle system and retractable tender mounts which all vanish below deck when not in use. To the bow the superyacht has an open-air cinema, sofas, as well as sunbeds.<img src="https://photo-assets.superyachttimes.com/photo/250640/image/large-a13390c2d0d384100b253bf4ba0354c0.png" data-gid="gid://syiq/Photo/250640">Internally, Project Canyon features the main dining on the owner’s deck aft, and on the deck above, the bridge deck there is the main salon offering stunning views. She can accommodate as many as 12 guests between six staterooms, with three doubles and two twins, both of which feature Pullman beds. The yacht's interior is modern, with wood veneers, stacked stone and tinted glass creating a earthy atmosphere. There are also plants situated throughout the interior adding a hint of natural colour.<img src="https://photo-assets.superyachttimes.com/photo/250634/image/large-9c61be4ccd671c87386b5c112922174b.png" data-gid="gid://syiq/Photo/250634">&nbsp;In addition to the 12 metre shadow vessel, Project Canyon is home to Seabobs, waverunners and a 5.15-metre WilliamJet Rescue Tender.&nbsp;
