The performance characteristics of a vee type planing hull are significantly increased by a combination of features for reducing drag and increasing attitude control. Exemplary of the former are a concave running pad to which air is inducted to reduce hull drag and an angled transom terminating at a transverse hull “step”which permits the outboard propulsion unit to be carried higher reducing unit drag. The presence of longitudinal “wedges”increase hull lift as planing speed is approached allowing the hull to plane at a lower speed. Transverse wedge elements positioned outboard of the concave running pad maintain a stern lifting torque for controlling bow up angle.

In a power boat hull having a plurality of chine pairs extending fore and aft intermediate the bow and transom thereof; the central one of said chine pairs straddling a centerline keel portion exhibiting a forward vee section and an aft concave section comprising a concave planing pad; said forward vee section merging with said planing pad via an upwardly and rearwardly directed transition area for introducing air to said concave planing pad as the hull approaches full plane and directing air and water thereto during full plane; said concave planing pad terminating at the after end thereof in a transverse step immediately adjacent and forward of said transom whereby water flowing thereacross includes an upward component at the plane of the transom; and the plane of said transom extending, from above the water line, downwardly and forwardly to said transverse step.
