The present invention relates to a wingsail structure (100) for a wind-assisted propulsion arrangement (10) of a marine vessel (1), which can be stowed in a space saving manner. The wingsail structure (100) comprises a wingsail frame (101) comprising a rigid or semi-rigid main wingsail (110) and flap (120) having an aerofoil, and at least one upper and lower coupling member (130; 140) connecting the main wingsail and the flap. The wingsail structure further comprises a foundation (20) arranged to be fixed to a body (3) of the vessel (1), the wingsail frame being rotatable in respect to the foundation. The upper and lower coupling members are configured to bring the main wingsail and the flap to a first unfolded standing position (I) and to a second folded standing position (IIa; IIb). The wingsail structure further comprises a tilting arrangement configured to bring the wingsail frame (101) from the second folded standing position (IIa; IIb) to a third tilted position (IIIa; IIIb).
