It's the exciting next step in raingutter racing. BSA® introduces an exclusive alternative to the original Raingutter Regatta® single-hull design-the NEW Trimaran Boat Kit! Built for stability and speed in the water, the trimaran hull is specially designed to prevent your boat from tipping over during the race.Kit comes with everything you need: an exclusive BSA® trimaran hull, two balsa wood outriggers, sail, mast, screws, sanding stick, and instructions. Trimarans can be raced in a separate class for additional Regatta fun; to ensure fairness to all participants, trimarans should not be raced against original single-hull boats. Be sure to check with your race chairman to determine the appropriate kit for your competition.
