Abstract: A floatation system for a marine vessel with a starboard pontoon, a port pontoon, and a center pontoon positioned therebetween. Outer strakes each extending along an outer length between forward and aft ends, each having an outer surface at an outer angle from a horizontal plane and an inner surface at an inner angle from the horizontal plane, and each being coupled to one of the starboard pontoon and the port pontoon. Inner strakes each extending along an inner length between forward and aft ends, each having an outer surface at an outer angle from a horizontal plane and an inner surface at an inner angle from the horizontal plane, and each being coupled to the center pontoon. The outer angles of the inner strakes are greater than the outer angles of the outer strakes and the inner angles of the inner strakes are less than 90°.

Abstract: A floatation system for a marine vessel having a deck. The floatation system includes three pontoons each having a cylindrical portion extending between forward and aft ends. The three pontoons include a starboard pontoon, a port pontoon, and a center pontoon positioned therebetween. Support members are coupled to the deck and to the three pontoons such that the three pontoons are interposed. Outer strakes each having a tip and an elongated portion, the elongated portions each extending along an outer length between forward and aft ends, are each coupled to one of the starboard pontoon and the port pontoon. Inner strakes each having a tip and an elongated portion, the elongated portions each extending along an inner length between forward and aft ends, are each coupled to the center pontoon. The aft ends of the outer strakes are aft of the aft ends of the inner strakes.
