Motor yachts over 10 m length are frequently used on open waters. VETUS stabilizers are the ideal solution for drastically reducing the rolling movement of these vessels in bad weather or in heavy swells. These stabilizers have been designed and specially developed for VETUS by Theo Koop, a worldrenowned expert in the field of ship stabilization.

Stabilizers consist of a hydraulically actuated pair of fins that are fitted to a vessel’s port and starboard midships sections underwater. They are controlled by an on board gyroscope and
automatically react to the rolling movement of the vessel to create a damping effect. In other words, rolling motion is reduced considerably by the use of VETUS stabilizers, resulting in increased comfort and reduced risk of seasickness. Stabilizers can to some extent, be compared with an aircraft’s ailerons, which considerably reduce movement in bad weather.

VETUS stabilizers are the ideal solution for drastically reducing the rolling movement of these vessels in bad weather or in heavy swells. These stabilizers have been designed and specially developed for VETUS by Mr. Theo Koop a world-renowned expert in the field of ship stabilization. In smooth water with the stabilizers not in use the speed reduction is negligible (for example about 1 knot at 25 knots for a 80 ft. vessel. In heavy seas however a vessel using stabilizers has the advantage because the boat rolls less and therefore has a lower wetted surface area.

Set of stabilizer electronics, 24 volt, control panel, computer, gyroscope, cylinders and valve block.

Does not include the stabilizer fins.

The shaft of each stabilizer fin is controlled by a set of hydraulic cylinders. These hydraulic cylinders are operated by the on board hydraulic system, powered by the main engine(s) or generator set. A gyroscope detects vessel movement and electronics and a valve block control oil flow to the cylinders, generating a movement in the fins to counter the roll. The valve block contains a solenoid valve controlling the direction of the fins, a centering valve for when going astern and an oil pressure control unit. Hydraulic hoses connect the hydraulic pump, the valve block and the hydraulic cylinders. If there is no hydraulic system already on board, then VETUS can also supply the components for this; see pages 21 and 22.
