ABSTRACT:
An airfoil sail system for a boat having a mast is disclosed. The airfoil sail system includes a front airfoil which is pivotal about an axis defined by the mast. The front airfoil has leading and trailing edges, and is generally symmetrical about a vertical plane extending between its leading and trailing edges. A rear airfoil is also provided which has leading and trailing edges. The rear airfoil is generally symmetrical about a vertical plane extending between its leading and trailing edges. A base member having a traveller is provided for operatively coupling the front and rear airfoils so that rotation of the front airfoil about its axis effects a counter-rotation of the rear airfoil to permit adjustment of the camber of the airfoil sail system.
