The present invention relates to a wingsail structure (100) for a wind-assisted propulsion arrangement (10) of a marine vessel (1). The wingsail structure (100) comprises a wingsail frame (101) comprising a rigid or semi-rigid main wingsail (110) and flap (120) having an airfoil shape, 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) and the wingsail frame is rotatable in respect to the foundation. The flap (120) is rotatable around a second longitudinal axis of rotation to bring the flap and the flap centerline (FCL) thereof in an inclined position in respect to the main wingsail centerline (MCL). The second axis of rotation is arranged laterally offset of the main wingsail centerline (MCL). In this way only one rotation axis is needed for inclining the flap.
