Sinot Reveals 118m FUSION Trimaran With 3,340m² of Exterior Deck Space

A 118-metre full-length trimaran concept

Sinot Yacht Architecture & Design has revealed FUSION, a 118-metre trimaran concept developed around unusually large exterior areas and distinct zones for culture, wellness, sport and exploration. The official project page gives an overall beam of 30 metres and an estimated gross tonnage of 8,200 GT.

Sinot says the naval architecture has been developed in close cooperation with Azure Yacht Design & Naval Architecture. FUSION remains a design concept rather than a contracted or launched yacht, so its published dimensions and arrangements should be treated as project specifications.

More than 3,000 square metres outside

The concept provides 3,340 square metres of exterior deck space, including roughly 2,200 square metres on the upper deck. A separate 834-square-metre tender, craft and vehicle deck is intended to carry large tenders, submersibles, water toys and expedition equipment.

Forward, a 770-square-metre play deck can support helicopter or VTOL operations as well as sports and event use. The arrangement illustrates how the trimaran beam is being used to separate guest life, technical operations and expedition equipment without concentrating everything around one conventional stern garage.

Wellness, pool and owner spaces

FUSION includes a 300-square-metre spa and wellness centre in the centre hull and an upper-deck pool measuring 8.2 by 12.5 metres. The owner’s residence is positioned aft on the uppermost deck and opens onto a private 100-square-metre terrace.

The accommodation plan is for 18 guests, including an owner’s stateroom, two VIP staterooms and six guest staterooms. Sinot lists a combined staff, crew and captain complement of 49, underlining the scale of the service and operational programme envisioned for the concept.

A concept for large-scale exploration

FUSION carries provision for two 15-metre limousine tenders and two additional 15-metre tenders, alongside expedition vehicles and diving equipment. The concealed lower-deck beach area in the centre hull provides direct water access while keeping the broad main-deck logistics zone above.

The project is being shown during Monaco Yacht Show 2026 as a design proposition rather than an announced new-build contract. Any future construction schedule, propulsion package or client status will therefore need separate confirmation from Sinot or an appointed shipyard.
