ABSTRACT:
A boat hull structure comprising a pair of laterally-spaced hulls having V-shaped bottom portions that are each symmetrical about a vertical plane extending through its longitudinal axis. A channel defined in each bottom portion that extends substantially along the length of each hull for trapping air and water to provide lift and to reduce "stuffing". Each channel defined by a pair of spaced, parallel and vertical channel walls and a horizontal base that interconnects the channel walls. A pair of strikes defined on each bottom portion that straddles the channel to define a high speed planing surface. The strikes preferably are located at the same elevation as the base of the channel so that the boat can plane on the strikes and the base of the channel at the same time. With this construction, the planing surface area of the boat hull structure is reduced, which enhances the speed performance of the boat hull structure.
