A sail propulsion element comprises a mast (3), an inflatable or non-inflatable sail (1) consisting essentially of two substantially fluidtight adjacent surfaces (5) joined together along their periphery, thus forming at least one closed cavity between them, an air conduit positioned between the inside and the outside of the cavity, at least one means for injecting air into the cavity, the sail once inflated having a profile that remains permanently symmetrical, irrespective of the movement of the propulsion element, or of the direction or strength of the wind, a headboard (10), and a sail receptacle (11). The mast is located forward of the center of aerodynamic thrust of the sail, the mast is or is not free to rotate by 360°, and the sail comprises at least one means maintaining a slight pressure in the sail.
