Abstract: A device for the roll-stabilization of a watercraft in motion, at anchor, or at zero speed, and/or for influencing the course of the watercraft, includes a fin-carrying shaft on which a guide fin is disposed. For changing an actual angle of attack of the guide fin in the water, the fin-carrying shaft is drivable by an electromechanical drive unit, and the drive unit is disposed on the hull using a base. An electromechanical drive unit is configured with a synchronous motor that drives the fin-carrying shaft using a reducing eccentric transmission. The device thereby has a significantly reduced installation space requirement, causes only slight operating noises, and is also optimally electronically regulable.

Abstract: An active stabilizing device for a primary damping of rolling movements of a ship or other watercraft including a hull including at least one positioning device having a drive journal and a stabilizing fin with a stabilizing surface and a root, the drive journal being attached to the stabilizing fin at the root, the stabilizing surface having a leading edge and a trailing edge and being configured to be disposed underwater. The positioning device is configured to set an angle of attack of the stabilizing fin by rotating the drive journal about a first axis of rotation and to pivot the drive journal about a second axis of rotation to move the stabilizing fin between a forward position and a rearward position relative to a bow of the watercraft.

Abstract: An active stabilizing device for a primary damping of rolling movements of a ship or other watercraft includes at least one positioning device including a drive journal and a stabilizing fin having a stabilizing surface and a root, the drive journal being attached to the stabilizing fin at the root, the stabilizing surface having a leading edge and a trailing edge and being configured to be disposed underwater. The positioning device is configured to simultaneously pivot the stabilizing fin about a pivot axis by a pivot angle and rotate the stabilizing fin about an axis of rotation. Also, a method of operating the active stabilizing device.
