A wingsail assembly comprises a main symmetrical aerofoil which is freely rotatable about an upright axis and a control vane which is settable about an upright axis spaced from the axis of the main aerofoil to cause the main aerofoil to adopt an angle of attack to the direction of the wind. A pivoted aerodynamic slot-forming vane assembly is rotatable in response to wind pressure to open and close respective slots, one on each side of the leading region of the main aerofoil. A linkage inhibits movement of the slot-forming vane assembly away from a neutral position when the control vane is set to a neutral position.
