Abstract
A water craft comprising: an elongated hull comprising a passageway having an inlet and an outlet; a pump jet disposed within said passageway intermediate said inlet and said outlet; said pump jet being configured to receive water entering said passageway through said inlet and pump said water out of said outlet, whereby to propel said hull through water; a plurality of nozzles disposed on the outer surface of said hull, aft of said inlet, wherein said plurality of nozzles are configured to release a friction-reducing fluid, whereby the friction-reducing fluid displaces water from the surface of said hull so as to diminish friction on the outer surface of said hull and facilitate high speeds.
Claims21
A water craft comprising:
- an elongated hull comprising a front end, a rear end, and a passageway extending through said elongated hull from said front end to said rear end, said passageway comprising an inlet opening at said front end and an outlet opening at said rear end;
- a pump jet disposed within said passageway intermediate said inlet and said outlet, said pump jet being configured to receive water entering said passageway through said inlet and pump said water out of said outlet, whereby to propel said hull through water;
- and
- a plurality of nozzles disposed on the outer surface of said hull, aft of said inlet, wherein said plurality of nozzles are configured to release a friction-reducing fluid, whereby the friction-reducing fluid displaces water from the surface of said hull so as to diminish friction on the outer surface of said hull and facilitate high speeds.
A method for moving through water, the method comprising:
- providing a water craft comprising:
- an elongated hull comprising a front end, a rear end, and a passageway extending through said elongated hull from said front end to said rear end, said passageway comprising having an inlet opening at said front end and an outlet opening at said rear end;
- a pump jet disposed within said passageway intermediate said inlet and said outlet, said pump jet being configured to receive water entering said passageway through said inlet and pump said water out of said outlet, whereby to propel said hull through water;
- and
- a plurality of nozzles disposed on the outer surface of said hull, aft of said inlet, wherein said plurality of nozzles are configured to release a friction-reducing fluid, whereby the friction-reducing fluid displaces water from the surface of said hull so as to diminish friction on the outer surface of said hull and facilitate high speeds
- submerging at least a portion of the elongated hull;
- and
- operating the pump jet so as to propel the water craft through water.
