  • Patent number: 9663212
    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.
