  • V-bottom planing boat with lifting recesses
    Patent number: 4722294
    Abstract: A V-bottom planing hull has longitudinally elongate recesses formed in its bottom surface symmetrically of and parallel to the hull centerline. The recesses are open at the forward and aft ends and are concave downwardly of the hull. The recesses are semicircular in cross-section. The recesses provide lift to the hull as water moves through them during forward motion of the hull. The lift generated in the recesses augments conventional planing forces created by the hull, allowing the hull to move faster.
