Abstract

The invention relates to an arrangement for stabilizing a watercraft, in particular for controlling the inclination (a) in a vertical plane perpendicular to the longitudinal direction of the watercraft (101) by enabling rotation of a movable keel structure and shifting of the centre of gravity sideways in relation to the centre line of the watercraft (101) to produce an inclination-correcting torque. The arrangement includes a single keel shaft (103) attached in a pivotally-movable (w) manner to the hull of the watercraft (101 ) and further a hull axle arrangement (202) connected to the hull bottom (201) of the watercraft (101) and arranged in a force-transmitting connection with the actuators (207).

Abstract

The invention relates to an arrangement for adjusting the keel structure of a watercraft, in particular for adjusting a keel fin meant for controlling tilting perpendicular to the longitudinal plane of an at least partially self-propelled watercraft (101) equipped with a movable keel fin, such as a sailboat or similar. The arrangement comprises at least one orientation member (221) for adjusting the angle of attack of the keel fin profile with respect to the direction of water flow.
