ABSTRACT:
A sail, according to one aspect of the present invention, comprises an inner membrane and two outer membranes, each attached substantially around the periphery of a respective side of the sail to form a respective pocket. The camber of the inner membrane is less than that of the outer sails so that, during use, the sail adopts an airfoil cross section. An inflatable compartment is provided adjacent the luff edge of the sail.
