According to the invention, the system is to that end characterised in that the moving means are configured for imparting a pivoting movement in the direction of the stem or the stern of the vessel to the at least one wing-shaped stabilisation element and setting a tilt angle of the at least one wing-shaped stabilisation element relative to the ship's hull in dependence on the speed of the vessel and the control signals delivered by the sensor means, such that the lifting effect generated by the at least one wing-shaped stabilisation element will have a damping effect on the ship's motion being sensed. ## Claims ### Claim 1 A system for damping a vessel's motion using a lifting effect, comprising: one first stabilisation element that extends from the vessel's hull, below the water line, on a side of the vessel, wherein at least one stabilisation element is configured as a wing, sensor means for sensing the vessel's motion and delivering control signals on the basis there of, moving means for moving the at least one wing-shaped stabilisation element relative to the hull, characterised in that the moving means are configured for imparting a non-rotatable pivoting movement in the direction of a stem or a stern of the vessel to the at least one wing-shaped stabilisation element and setting a tilt angle of the at least one wing-shaped stabilisation element relative to the ship's hull in dependence on the speed of the vessel and the control signals delivered by the sensor means, such that the lifting effect generated by the at least one wing-shaped stabilisation element will have a damping effect on the ship's motion being sensed. ### Claim 2 (depends on 1) A system according to claim 1, characterised in that the moving means are configured for setting the at least one wing-shaped stabilisation element at a tilt angle at a sailing speed v=0 kn whilst at the same time imparting an angular displacement movement relative to the ship's hull to the at least one wing-shaped stabilisation element. ### Claim 3 (depends on 1) A system according to claim 1, characterised in that the moving means are configured for imparting a variable tilt angle to the at least one wing-shaped stabilisation element at a speed v≠0 kn whilst at the same time setting a fixed pivot angle of the at least one wing-shaped stabilisation element relative to the hull. ### Claim 4 (depends on 1) A system according to claim 1, characterised in that the wing-shaped stabilisation element is connected to the vessel by means of a universal joint. ### Claim 5 (depends on 1) A system according to claim 1, characterised in that the wing-shaped stabilisation element can be accommodated in a recess provided in the ship's hull. ### Claim 6 (depends on 1) A system according to claim 1, characterised in that at least one wing-shaped stabilisation element is provided on each longitudinal side of the vessel. ### Claim 7 (depends on 6) A system according to claim 6, characterised in that the set of wing-shaped stabilisation elements is provided near the rear of the vessel. ### Claim 8 (depends on 1) A system according to claim 1, characterised in that the wing-shaped stabilisation element is provided with a winglet at its free end. ### Claim 9 (depends on 8) A system according to claim 8, characterised in that the winglet is directed toward the water surface. ### Claim 10 (depends on 8) A system according to claim 8, characterised in that the winglet is directed away from the water surface. ### Claim 11 (depends on 1) A system according to claim 1, characterised in that the wing-shaped stabilisation element has an Aspect-Ratio ranging between 1 and 10, wherein the Aspect-Ratio is a length dimension of the wing-shaped stabilization element divided by an average horizontal width of the wing-shaped stabilization element. ### Claim 12 (depends on 1) A system according to claim 1, characterised in that the system further comprises location determination means, and that the moving means impart the non-rotatable pivoting movement in the direction of the stem or the stern of the vessel to the at least one wing-shape'd stabilisation element in part on the basis of the determined position of the vessel.
