ABSTRACT:
The present invention entails a variable camber airfoil assembly mounted on a vessel and having a pivotably mounted rigid leading edge member. The rigid leading edge member includes an elongated generally V-shaped member that extends substantially the entire length or height of the airfoil assembly. A mast forms a part of said airfoil assembly and extends between a tip member and a root member and wherein said leading edge member is mounted forwardly of the mast. Extending between said tip member and root member rearwardly of the mast is a flexible cable. The variable camber feature of the present invention is formed by a pliable skin having two opposed sides that are interconnected between the leading edge member and the flexible cable. To limit the extent of pivotable movement of the leading edge member, the mast is extended between two sides thereof that form its general V-shape. By the provision of the leading edge member being pivotable, it is appreciated that the same can easily pivot with respect to the boat or vessel for a more effective and efficient entry into the wind.
