B63B 3/00

US Classification:

440 6, 114 6131, 440 38

Abstract:

Disclosed herein is a self-propelled personal water craft including a parabolic hull. The hull has a bow, mid-section and stern. The mid-section has substantially reduced diameter compared with the bow and stern section defining an hour-glass hull shape. The hull including an upper portion and a lower portion, a hollow space is created between the upper and lower portions and defines a central portion. The lower portion includes structure for manipulating water drag. Additionally, the craft includes a motor member for propelling the craft. In an exemplary embodiment, the motor member includes an axial flow jet pump.

Abstract:

A self-propelled personal watercraft. The watercraft includes a hull with a middle narrower than a bow and a stern of the watercraft and with a bottom of the bow being raised with respect to the middle and the stern, and a propulsion device within the hull. While the watercraft is propelled through water by the propulsion device with a rider on board, shifting of the rider's weight to either side of the watercraft increases contact of the bow with the water on that side, the increased contact resulting in increased drag and turning the watercraft to that side. While the watercraft is propelled through water by the propulsion device with the rider on board and the watercraft is not turning, the bottom of the bow makes contact with the water across a narrower distance than the bottom of the middle.
