<p>A system for controlling the jibe movements of a sailboat boom (4), which boom has an outer free end (5) connected to the boat (4) via a sheeting arrangement (6), and an inner end (7) fixed to the mast (3) via a pivot joint (8). A hydraulic actuator (13) is connected with the inner boom end (7) at the pivot joint (8) via a vertically extending axle (9). The actuator can be controlled to swing the boom over the centreline of the boat during a jibing manoeuvre, as well as can be adjusted to perform a momentum acting against the swinging of the boom eliminating violent, uncontrolled jibing manoeuvres.</p> |
