Abstract
A method is described for attenuating the oscillation of a ship, which includes a controller of a drive adapted to move at least one fin to allow stabilizing the ship, when the ship is at zero speed, anchored, wherein the motion of such at least one fin comprises an initial acceleration step, an intermediate step at constant speed and a final deceleration step. In the initial acceleration step, such at least one fin can start from a first angular position, while in the final deceleration step, such at least one fin can reach a second angular position corresponding to minimum or null values of effects opposite to those of the acceleration and constant speed steps of such at least one fin to allow maximizing the useful roll moment generated by such at least one fin.
