The invention relates to an at least partially wind-propelled ship, comprising a double airfoil mounted on a structure controlled angularly around a generally vertical axis depending on conditions, where the double airfoil comprises a fore flap and an aft flap at least one of which has a fore-to-aft asymmetry and separated by a slit, where each flap comprises a series of shape members distributed in height, wherein said structure comprises a fore mast and an aft mast connected by a boom member and by a gaff member.The shape members of the fore flap are traversed by the fore mast while being able to turn around an axis defined thereby, while the shape members of the aft flap are traversed by the aft mast while being able to turn around an axis defined thereby.In addition, the aft mast is twistable, the shape members of the aft flap are rotationally locked to said aft mast, and the controller is capable of acting on the bottom and the top of the aft mast.
