ABSTRACT:
A planing-type hull has a keel which projects downwardly from a disk which is mounted in the bottom of the hull for limited rotational movement about a vertical axis located rearwardly of the center of the keel. In a second embodiment the keel projects downwardly from a sector or generally pie-shaped member, which is pivotal in the bottom of the hull between two limit positions. A spring-loaded detent may be employed to return the keel to a centered position.
