ABSTRACT:
In a boat of the "planing" or "semiplaning" type and in which the rear portion of the bottom is substantially straight in the longitudinal direction and tapers rearwardly, the side faces of the hull are formed with rearwardly facing steps crossing the highest waterline and placed substantially at or behind the point of maximum bottom width, so as to cause ventilation of the rearwardly converging side faces at speeds below planing speed. This substantially eliminates the resistance caused by suction on said faces and permits the bottom to be given a pronounced rearward taper with a width of the bottom at the stern less than 70% of maximum width, with consequent improved performance at low speeds. To minimize flow disturbance the steps taper towards both ends and extend upwards and forwards with decreasing inclination.
