ABSTRACT:
A low draft, hydroplane-like vehicle in which the engine and associated equipment is so located in the hull that the engine not only drives a jet pump to power the vehicle but the weight and location of the engine and associated equipment[imparts an], relative to the center of buoyancy of the vehicle, renders the vehicle stable only when it is in an upright position, and the vehicle will immediately right itself from any overturned position. In addition, the weight and location of the engine and associated equipment imparts an imbalance to the vehicle except when a user is mounted thereon. Due to this imbalance [the vehicle is stable only when in an upright position, and will immediately right itself from any overturned position. A further result of this imbalance is that] the bow is submerged to a substantially greater depth than the stern when a user is not mounted on the vehicle, and as a result the vehicle will slowly circle should the user be inadvertently displaced therefrom. Such slow circling permits the user by swimming a short distance to recapture the vehicle.
