The forced air cavity and control system for watercraft provides a source of compressed air against the hull, the compressed air being distributed via a pivotally adjustable air scoop mounted proximate the front of the boat, to which is connected a series of conduits (air passageways) leading downwardly from the housing. The conduits exit at openings in a V-shaped step in the hull of the watercraft to emit high pressure air against the hull to thereby reduce friction caused by hull contact with the water. A hydraulic ram operably connected to the air scoop provides a means of pivotal adjustment. A plurality of ice runners is provided on the bottom of the watercraft to increase stability of control under reduced water friction conditions.

I claim: 1. A forced air cavity and control system for a watercraft, comprising: a housing defining an air chamber adapted for mounting atop the watercraft; an air scoop pivotally attached to the air chamber, the air scoop adjustably pivoting to regulate a flow rate of air into the air chamber when the watercraft is in motion; at least one air passageway connected to the air chamber; at least one V-shaped step defined in a hull of the watercraft, the step having at least one air outlet port defined therein, the air passageway extending to the air outlet port, the V-shaped step being formed by two legs; and a plurality of elongate ice runners adapted for extending longitudinally on the hull of the watercraft and located aft of the at least one V-shaped step, wherein air entering the scoop is ejected from the air outlet port, the ejected air reducing drag on the hull of the watercraft. 2. The forced air cavity and control system for watercraft according to claim 1, further comprising a dowel extending longitudinally along the elongate ice runners. 3. The forced air cavity and control system for watercraft according to claim 1, wherein said at least one air outlet port comprises a plurality of air outlet ports, said at least one air passageway comprising a first plurality of air passageways connected to the air outlet ports disposed in one leg of the V-shaped step, said at least one passageway further comprising a second plurality of air passageways connected to the air outlet ports disposed in the other leg of the V-shaped step. 4. The forced air cavity and control system for watercraft according to claim 1, further comprising: at least one actuator connected to the air scoop, the actuator being extendable and retractable to adjustably open and close said air scoop; an actuator control switch operably connected to the at least one actuator. 5. The forced air cavity and control system for watercraft according to claim 4, wherein said at least one actuator comprises a hydraulic ram. 6. The forced air cavity and control system for watercraft according to claim 1, further comprising: a water drain disposed in a floor of the air chamber; a tube connected to the water drain, the tube leading to the air passageway and providing suction to drain excess water from the air chamber. 7. The forced air cavity and control system for watercraft according to claim 6, wherein the floor of the air chamber is concave. 8. The forced air cavity and control system for watercraft according to claim 1, further comprising a cover plate disposed over the housing. 9. The forced air cavity and control system for watercraft according to claim 1, further comprising a columnar brace reinforcing attachment of the air chamber and air scoop to the watercraft. 10. A watercraft having a forced air cavity system, the watercraft comprising: a boat having a bow, a hull, and a stern; a plurality of elongate ice runners extending longitudinally below the hull; a housing defining an air chamber atop the boat; an air scoop pivotally attached to the housing, the air scoop adjustably pivoting to regulate a flow rate of air into the air chamber when the watercraft is in motion; at least one air passageway connected to the air chamber; and at least one V-shaped step defined in a hull of the watercraft, the step having at least one air outlet port defined therein, the air passageway extending to the air outlet port, the V-shaped step being formed by two legs and located forward of the plurality of ice runners. 11. The watercraft according to claim 10, further comprising an auxiliary V-shaped step disposed on the hull. 12. The watercraft according to claim 10, further comprising a dowel extending longitudinally along the elongate ice runners. 13. The watercraft according to claim 10, wherein said at least one air outlet port comprises a plurality of air outlet ports, said at least one air passageway comprising a first plurality of air passageways connected to the air outlet ports disposed in one leg of the V-shaped step, said at least one passageway further comprising a second plurality of air passageways connected to the air outlet ports disposed in the other leg of the V-shaped step. 14. The watercraft according to claim 10, further comprising: at least one actuator connected to the air scoop, the actuator being extendable and retractable to adjustably open and close said air scoop; an actuator control switch operably connected to the at least one actuator. 15. The watercraft according to claim 14, wherein the at least one actuator comprises a hydraulic ram. 16. The watercraft according to claim 10, further comprising: a water drain disposed in a floor of the air chamber; a tube connected to the water drain, the tube leading to the air passageway and providing suction to drain excess water from the air chamber. 17. The watercraft according to claim 16, wherein the floor of the air chamber is concave. 18. The watercraft according to claim 10, further comprising a cover plate disposed over the air scoop. 19. The watercraft according to claim 10, further comprising a columnar brace reinforcing attachment of the air chamber and air scoop to the watercraft.
