A reversible wing sail for use with a wind-powered vehicle is provided herein that comprises a rotatable mast, a multi-surface sail cover, and a spring-assisted camber inducer. The rotatable mast generally has a longitudinally extending mast axis and the multi-surface sail cover runs along at least a portion of the mast, extending transversely in relation to the mast from a leading edge to a trailing edge. The sail cover has a first surface and a second surface that form a cavity therebetween. The spring-assisted camber inducer is arranged in the cavity between the first and second surfaces of the sail cover and configured to induce an asymmetric camber profile between the first and second surfaces to form the wing sail into an airfoil shape.
