Abstract
A second hull adaptor is provided for use with a jet powered personal water craft. The second hull provides for the craft to be more buoyant and stable even when used by full-sized adults. The second hull has a water induction channel which specifically directs the movement of water through the jet pump thereby increasing speed. It further has angled sides and diverging chines for increased speed and improved handling. An adjustable sleeve surrounds the water exhaust nozzle allowing for further adaption of the craft to water conditions or for specific riding styles. The sleeve may be adjusted so as to be flush with the rear transom to a position fully extend beyond the transom as desired.
Claims12
A second hull to be coupled to a water craft which has a water jet outlet and a first hull which has an exterior surface including a bottom surface and side surfaces, said second hull comprising:
- a hull body sized and shaped to closely fit the exterior surface of the first hull of the water craft so that at least a portion of the first hull can be inserted therein, said hull body also having a front, a back, and a bottom surface and at least one chine at said bottom surface of said hull body to increase the flotation and stability of the water craft, a slot in said bottom surface to receive the water jet outlet of the water craft;
- and
- a ride plate secured across said slot in the bottom surface of said second hull.
A second hull to be coupled to a water craft which has a water jet outlet and a first hull which has an exterior surface including a bottom surface and side surfaces, said second hull comprising:
- a hull body sized and shaped to closely fit the exterior surface of the first hull of the water craft so that at least a portion of the first hull can be inserted therein, said hull body also having a front, a back, and a bottom surface and at least one chine at said bottom surface of said hull body to increase the flotation and stability of the water craft, said bottom surface has separate openings therethrough for water intake and water expulsion.
In combination:
- a water craft including an engine exhaust pipe, a water exhaust nozzle and a first hull having a bottom and a rear transom;
- a second hull including an engine exhaust port and a water exhaust port formed therein, said second hull having a bottom and being sized to completely surround and closely fit the bottom and rear transom of said first hull such that said engine exhaust pipe and said water exhaust nozzle of said water craft extend through respective ones of said engine exhaust port and said water exhaust port of said second hull;
- and
- fastener means for attaching said second hull to the first hull of said water craft.
A water craft including and water jet nozzle and a first hull having a stern, together with a second hull coupled to said first hull, said second hull comprising:
- a hull body having a stern, having an opening in said stern;
- the water jet nozzle of the water craft extending through said opening in said stern;
- a sleeve surrounding the water jet nozzle, said sleeve being movable so that it can be adjusted from a position where it does not extend beyond said stern to a position where it extends beyond said stern.
