A wind turbine mechanically connected to electric generating means wherein the action of the wind upon said turbine causes rotation of said turbine about an essentially vertical mast thereby converting wind power to electric power for the propulsion motors of a screw-propelled ship comprised of a number of hubs rotatably mounted and equally spaced along the length of a vertical mast; each of said hubs supporting radially disposed arms equally spaced about the circumference of said hubs; said arms vertically alligned by torque tubes coaxial with said mast and situated between adjacent hubs and connected to them; two horizontally disposed flexible yards vertically alligned with each other and sufficiently spaced apart to form a slot between them, said yards secured tangentially to the end of each of said arms; all of each set of vertically alligned yards secured at their yardarms by a vertically disposed and circumferentially situated brace member; each of said brace members secured by cables, said cables spaced in said slots and alligned by sheaves rotatably mounted upon each of said arms; the free length of each of said cables controlled by a windlass rotatably mounted upon each of said arms; and sail cloth secured to said yards, said sail cloth stretched between adjacent yards of said adjacent hubs.
