Abstract

An improved lateen rigged sailing board is disclosed that basically combines a sailing board with a mast mounted thereon which is swivelly mounted to the upper surface of the sailing board, and which is provided with means to prevent the mast from completely falling forward. The mast is particularly configured with a wishbone or hoop-like section therein, through which the lateen sail is passed. The boom of the sail is secured within the lower portion of the hoop-like section, while the gaff of the sail is hoisted toward the upper portion of the hoop-like section by a halyard that may conveniently pass through the upper end of the hoop-like section and be secured by a simple expedient of a cam cleat. The arrangement is such that the mast will allow the center-of-effort of the sail to be adjusted relative to the sailing board and allow the entire unit to be tacked through the wind and move upward.
