Abstract: The invention relates to an active roll stabilisation system for ships, comprising at least one stabilisation element (10) extending below the water line, which is mounted on a rotary shaft (4,40) that extends through the ship's hull, sensor means for sensing the ship's movements and delivering control signals on the basis thereof to rotation means for rotating the rotary shaft (4,40) for the purpose of damping the ship's movements that are being sensed by means of the stabilisation element.The object of the invention is to provide an active roll stabilisation system for ships that can be used both with sailing ships and with ship that are at anchor. According to the invention, the active roll stabilisation system is to that end characterized in that the stabilisation element (10) is provided with a sub-element (12,120) that is movable with respect to the stabilisation element. This makes it possible to impart an additional lifting moment to the ship via the stabilisation element (10), both while the ship is sailing and while the ship is at anchor, for the purpose of effectively damping or countering the ship's movements that are being sensed.
