A wingsail assembly comprising a thrust wing having a leading aerofoil (1) and a trailing aerofoil (2), the leading and trailing aerofoils being deflectable with respect to one another to adopt a cambered configuration, characterised in that the trailing aerofoil has a cross- sectional shape with a relatively flat leading edge interconnecting relatively strongly curved corners (5,6) on opposite sides of the aerofoil, such that for each direction of relative deflection between the leading and trailing aerofoils the corner more remote from the trailing edge of the trailing section provides an aerodynamic leading edge for the trailing section and the corner more proximate the trailing edge of the leading section provides an inner wall for a convergent slot. The assembly is mounted on a vessel via a bearing having an axis passing through the trailing section. A tail aerofoil trims the assembly and is mounted on a boom extending from the trailing section.
