Method for rigging and controlling a wing sail

A rigging for a wing propelled craft comprises a mast having a starboard side and a port side, wherein the mast is controllably rotatable in either direction about a longitudinal axis; a flexible sail comprising a star-board flexible sail portion and a substantially identical port flexible sail portion, each flexible sail portion having a luff and a leach, wherein the luff of each sail portion is connected to a respective side of the mast; and a plurality of elongated battens, each of which extends substantially between the luff and the leach of one of the respective sail portions, each of which is in contact with the respective flexible sail portion. Rotation of the mast causes the battens connected to one of the sail portions to be compressed along their length so as to bend one of the sail portions to increase the camber thereof and causes the battens connected of the other sail portions to be tensioned along their length so as to partly straighten the other sail portion which changes the shape of an aerofoil formed by the sail..
