ABSTRACT:
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.
