Abstract

PURPOSE: To reduce friction resistance, rolling angle, and wave making resistance and the like by providing the recess in a longitudinal direction for alongside the stern of the ship in conjunction with a large bossing keel.
CONSTITUTION: A recess 8 is provided for alongside the ship of both sterns 6 of the bossing keel 3 in a parallel with the keel 3, besides, allowing to reach to the central end of the ship length from the stern, the back of the recess is joined with the front bilge 10 in a step manner 9, providing, besides, the water separation gas injection hole 12 for the ceiling 11 of the back of the recess 8. Besides, the width of the keel 3 is gradually increased as extending from the bow to the center, giving the maximum at nearby the central section, allowing to reduce as extending to the stern to form the skeg. This enables to reduce the wetted surface, allowing the paddle 14 difined at the exterior of the recess 8 to give a damping action at rolling, enabling to reduce the necessary cruising surface and the trimming angle, and enabling to reduce the wave-making resistance of the existing cruising hull.
