The wingsail as shown in the accompanying figures comprises of an operatively upper end plate, an operatively lower end plate and an aerofoil extending between the operatively upper and lower end plates. The aerofoil of the wingsail comprises a leading edge and a trailing edge, the leading edge being inclined operatively forwardly as it extends between the operatively lower end plate and the operatively upper end plate.
In FIGS. 1 to 10, the wingsail is shown in a neutral condition with the aerofoil having an aerofoil section being symmetrical about a neutral camber line passing between the leading and trailing edges. In FIGS. 11 to 20, the wingsail is shown in a first deformed condition with the aerofoil taking a first reflexed camber aerofoil section shape, as clearly shown illustrated in FIG. 14. In FIGS. 21 to 30, the wingsail is shown in a second deformed condition with the aerofoil taking a second reflexed camber aerofoil section shape, as clearly shown illustrated in FIG. 24.
