This 31ft 10inch model replaces the corsair 31. Corsair have sold 303 of the previous model and the Corsair 970 is roomier with more focus on comfort without sacrificing performance. The Corsair 970 Carbon takes the trailerable folding trimaran concept forward by using Carbon spars and upgraded Aramid sails to provide more power to the 970 hull. This is a high performance version of an already comfortable but quick trimaran.
