ABSTRACT:
An upright mast is mounted from the lateral center of the hull of a sail boat having opposite sides. The lower end of the mast is pivotally supported from the hull for angular displacement about a horizontal fore and aft extending axis adjacent the lower end of the mast and the upper end portion of the mast includes mast stay guide structure relative to which elongated flexible mast stays are guidingly engaged along their midportion for longitudinal displacement relative to the stay guide structure. One pair of corresponding ends of the stays are anchored relative to the hull opposite sides and the other pair of corresponding ends of the stays depend downwardly along the mast. Latch structure releasably anchors the other ends of the stays against upward movement along the mast and the latch structure includes high heel angle sensing release structure operative to release the other end portions of the stays for upward movement along the mast responsive to the hull experiencing a high heel angle above a predetermined maximum desired heel angle. Further, structure is connected between the hull and the mast, independent of the stays, operative to yieldingly resist angular displacement of the mast relative to the hull from a predetermined center position of the mast.
