- Stabilizers are mainly used on passenger ships to make the journey more comfortable for the passenger and to avoid the occurrence of seasickness among the passengers. Stabilizers are also used on ferries and container ships, which could cause major damage if the cargo slipped.
- the hull can be welded to the hull.
- this type of stabilizer is very inexpensive, it has the disadvantage that it is generally poor in effectiveness and, because it is welded on, it has a permanent braking effect on the hull of the ship.
- fin stabilizers are used in the prior art and in particular in large ships.
- This system uses movable fins on the ship's hull to straighten the ship under the pressure of the water current.
- the fins can be swiveled in and out of the ship's hull and the angle of attack can be adjusted hydraulically depending on the roll movement of the ship.

- the redundant hydraulic system 1 from FIGS. 4 and 5 can be operated according to an exemplary embodiment as follows:
- the 2/2 way valves 24a, 26a, 24b, 26b are blocked in order to swing the stabilizing wing out of the hull of the ship.
- the first hydraulic pump 21a and / or the third hydraulic pump 21b control the rotary vane motor 5 and the hydraulic cylinder 22 with the first line 72 and via the 4/3 way valve 60 and the further 4/3 way valve 62.
- the 4/3 Directional control valves 60 and 62 open so that the stabilization wing 4 can be swiveled out and the angle of attack of the stabilization wing 4 swung out can be controlled (see FIG. 5).
- the 2/2-way valves are blocked again and the first hydraulic pump 21a and / or the third hydraulic pump 21b work again via the 4/3-way valves 60 and 62.
- a first high pressure circuit 100 actuator (rotary vane motor 5 or
