Folding and unfolding a Corsair trimaran takes only a minute. With just 4 bolts to remove, it is easily managed by one person, and is normally done while afloat. Simply raise (to fold) or press down (to unfold) the inboard end of one cross beam. It can be done from the safety of the cockpit and only a little force is needed due to the folding system’s carefully balanced geometry, and the movement of the floats being mostly horizontal.

The solid aluminium folding struts have absolute control over the folding motion and prevent flexing or racking. A stainless steel bolt on the inboard end of each beam secures the floats for sailing. Crucially, wingnets remain attached during the folding process – their frictionless fixing allows them to tension themselves appropriately through the folding process. The system is so simple and balanced that Corsair trimarans can even be folded while motoring.
