A wind propulsion unit including a dual wingsail mounted on a structure that is angularly controlled about a generally vertical axis depending on the conditions, the dual wingsail including a front flap, a rear flap and a supporting structure that allows the front flap and the rear flap to pivot about two axes that are generally parallel and spaced apart from one another, the unit also including a device for controlling the orientation of the rear flap according to the direction of incidence of the wind during propulsion. The device for controlling the orientation of the rear flap is also configured to bring the rear flap, when the wind propulsion unit is in an inactive position, into a folded orientation wherein a substantial portion of its cross-sectional extent is positioned along a substantial portion of the cross-sectional extent of the front flap.
