ABSTRACT:
A hull configuration for a small watercraft of the jet propelled type that is designed to accommodate one or more riders seated in straddle fashion on a seat with a pair of depressed foot wells on opposite sides of the seat that extend through the transom of the hull. An elongated cavity is formed in the hull and a pair of transversely spaced apart flotation devices are positioned in the hull to add to its buoyancy whether erect or inverted. A vent system is provided for the cavity for ventilating the engine compartment formed therein and also for insuring against the inclusion of water in significant amounts in the cavity when the watercraft is inverted. An improved flap type check valve is provided in the foot areas for permitting water to drain therefrom and preclude water entry thereto.
