A rigging comprises a mast controllably about a longitudinal axis; a flexible sail comprising a starboard and port flexible sail portions; a plurality of elongated battens which extend a luff and a leach of sail portions; each batten is pivotally connected to a respective outermost part of the respective side of the mast. Rotation of the mast causes the battens connected to one of the sail portions to be compressed along their length and causes the battens connected of the other sail portions to be tensioned along their length so as to change the shape of an aerofoil formed by the sail.
