SAILING BOAT AND METHOD OF OPERATING THE SAME Abstract of the Disclosure A sailboat having a hull, a sail assembly and a keel. The keel is shaped as a longitudinally and horizon- tally extending hydrofoil which develops a vertically downward force. When the boat is traveling in a heeled position, the keel member exerts a downwardly and outwardly directed keel force having a lateral force component to substantially counteract an opposite lateral aerodynamic force component exerted by wind against the sail assembly, thus diminishing the yaw angle in the travel of the boat. Further, the keel force acts through the center of gravity of the boat to produce a righting moment which tends to counteract the capsizing moment developed by the force of the wind against the sail assembly. -1-
