Dutch Sinot Yacht Architecture & Design’s ambitious flagship concept is positioned as the “world’s largest full-length trimaran concept”. Unlike classic trimarans with short outriggers, the Fusion features three hulls of almost equal length (a 115-meter central hull and two 110-meter side hulls) that form a monolithic architectural platform

The megayacht’s beam is 30 m, the area of her exterior decks is over 3,300 sq.m, and her internal volume is about 8,200 GT. It is obvious that there is enough space not only for accommodating 18 guests and a crew of 49, but also a lot of equipment and most advanced and extensive amenities.

The Fusion is said to unite two polar recreation scenarios, as there is everything needed for culture and wellbeing, as well as for sports and exploration.

The trimaran’s foredeck is referred to as the “playdeck”. It is home to a full-sized tennis court, which can transform into an open-air space for doing sports or live music DJ performances. It can also host a a helicopter or VTOL craft.

The upper deck is home to a dining table for 18 and a pool with a see-through bottom, allowing the sunlight to reach the lower levels. 

The “expedition” section of the main deck takes up 843 sq.m and carries four 15-metre tenders, dive gear, water toys, mini submersibles and even expedition vehicles.

In addition, the main deck is home to a cinema featuring a vast 8K MicroLED video cinema wall and a wellness centre of about 300 sq.m with massage and physiotherapy rooms, saunas, a hammam and a counter-current pool.

The guest cabins, including two VIPs and six standard cabins, are located on the main deck. Each cabin’s layout is organised around a central zone incorporating a dressing area, bathroom and bed, with passageways on both sides and private loggias with glass transoms. The VIP cabins are equipped with private saunas.

The cultural part of the project is presented by numerous art objects and the interior aesthetics. The “architectural heart” of the Fusion is the grand central staircase in the lobby, which connects the aft and forward areas. Its steps go round the freestanding art installation, embodying the concept of fusion, with internally illuminated glass and pieces of handcrafted natural stone.

Another large installation can be found on the main deck behind the lift: the piece is made from solid cast-glass sheets to look like an eruption of water frozen in time.

“Fusion is not a standard yacht with extra stabilisers,” says the studio founder and principal designer, Sander J. Sinot. “Three near-full-length hulls come together as one architecture, and that changes what is possible aboard a yacht of this size. Our owners no longer want to choose between culture and adventure, between serenity and action. Fusion is designed so they don’t have to. The essence of Fusion is freedom: the freedom not to choose between different ways of living, but to embrace them all.”
