Abstract

Bei einem Wasserfahrzeug mit einer Stabilisierungseinrichtung, läßt sich die Stabilisierung des Wasserfahrzeuges insbesondere bei starkem Wellengang verbessern, wenn über die Länge der Konstruktionswasserlinie eines Schiffes (1), unterhalb der Wasseroberfläche (2) beidseitig am Kiel (3) Stabilisierungsplatten (4) angeordnet sind, die nicht über die Rumpfbreite (5) hervorkragen.

Figure 00000001
In the case of a watercraft with a stabilization device, the stabilization of the watercraft can be improved, particularly in strong waves, if stabilization plates (4) are arranged on both sides of the keel (3) over the length of the construction waterline of a ship (1), that do not protrude beyond the fuselage width (5).
