In a market largely dominated by catamarans, there are few production trimarans available for ocean cruising. It is in this niche that the new shipyard Welling Marine and the design firm 3 Lignes Architecture Navale are positioning themselves with the Well 53, a 16.17-meter trimaran project currently in the preliminary design phase.
A trimaran designed for offshore cruising
The Well 53 incorporates the characteristics typically associated with trimarans?particularly their seakeeping qualities?while seeking to meet recreational sailors? expectations for livability. The designers have thus announced a large central pod combined with an interior layout inspired by catamarans.
The cockpit spans the entire aft width of the boat, while the deck layout was designed to prioritize ease of maneuvering and ergonomics. The boat is intended for ocean cruising, with a focus on ease of use.
The trimaran has a hull length of 16.17 m and a beam of 9.97 m. Its estimated displacement is 17.5 metric tons. It will be built entirely of composite materials. The sail plan calls for 180 m² when sailing upwind and up to 320 m² when sailing downwind.
A new construction project in partnership with an experienced architecture firm
Founded in 2026, Welling Marine was born out of a collaboration between Guillaume Collignon and Sébastien Follain. The shipyard plans to build in small batches, with the flexibility to adapt the vessels to the owners? sailing plans.
The design of the Well 53 was entrusted to 3 Lignes Architecture Navale. Based in Lorient since 2019, the firm works on both new projects and technical studies for various shipyards. Its founder, Nicolas Purnu, has over twenty years of experience in multihull design, notably at a leading naval architecture firm in La Rochelle.
With this 53-foot project, Welling Marine and 3 Lignes Architecture Navale aim to offer an alternative to cruising catamarans in a segment where trimarans are still relatively rare today.
