Sailboard step design with less ventilation and increased speed

机译:帆板台阶设计,通风少,速度快

摘要

A step shape in a planing hull for water craft and more particularly for sailboards, surfboard or PWC for increasing the lift in front of the step and decreasing it in back at high planing speed, which has dynamic lift directly behind the step when the hull is traveling at a transition speed between displacement mode and planing mode, but at high planing speed it does not have lift directly behind the step. The hull has increased speed because the lift behind the step at transition speed allows the position of the step to be moved forward and in one embodiment has cambered surface (9) in front of the step. This step does not go across the full width of the hull such that there is a continuous planing surface in front of the fins or other means, which it is desirous that they not ventilate, and fin or other means has more ventilation resistance in another embodiment.
