Vee hull construction

摘要

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.
