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 rail system for a marine vessel having an upper deck. The rail system has a set of forward rails that encloses a portion of the upper deck, where the set of forward rails includes a front rail and folding side rails. The set of forward rails is pivotable between an up position and a down position. A plurality of floor hinges pivotally couple the folding side rails to the upper deck. The set of forward rails has an up height when in the up position and a down height when in the down position that is lower than the up height.
