ABSTRACT OF THE DISCLOSURE The invention provides a batten structure which can be placed inside a double sided sail to provide a so-called "wing" sail having an airfoil section which can be close to an ideal airfoil on either tack. The structure includes a central beam which engages the mast, a nose piece pivotably connected to the front end of the beam, and two flexible batten members each extending rearwardly from rigid connections on opposite sides of the nose piece and being slidably connected together at their rear ends. Spreaders which are movable relative to the beam connect the batten members and maintain its airfoil shape while allowing the batten members to flex when the wind moves from one side of the sail to the other.
