Abstract
Method and apparatus in a system in connection with the spinnaker pole (8) or similar of a sailing boat, in which system a control line (12, 13) is attached to both guys (6, 7) of the sail (4). The control lines (12, 13) are arranged to run through the pole (8) and to move a piston (20) and the piston (20) is connected to means, with the aid of which the length of the pole (8) can be altered or the pole can be lowered to a lower position at its outer end. The piston (20) is preferably moved by the lines running around pulleys (23) and attached to the moving part (17) of the telescopic pole.
Claims14
A method of controlling a spinnaker pole (8) or similar of a sailing boat;
- in which a sheet (6) and a guy (7) are attachable to a spinnaker sail (4) and having a fore triangle, characterized in that control lines (12, 13) are arranged to travel through the spinnaker pole (8) and are arranged to move a piston (20) and that the piston (20) is connected to means to alter the length of the pole (8), or to lower the outer end of the pole, the method comprising the steps of choosing a first gybe to be sailed, actuating the control line (12 or 13) on the chosen gybe side, swinging the spinnaker pole to the chosen gybe side through the fore triangle and allowing the spinnaker pole to elongate or raise by movement of the piston, starting a second gybe by un-actuating the actuated control line (12 or 13) and actuating the opposing control line (12 or 13J permitting the piston to move and shorten or lower the spinnaker pole, and swinging the spinnaker pole to the second gybe side through the fore triangle.
A spinnaker control apparatus for a sailing boat, in which a sheet (6) and a guy (7) are attachable to a spinnaker sail (4), comprising a pole (8), a piston (20) movable inside the pole (8), control lines (12, 13) for attachment to the sheet and guy, and fixed stops (14) in control lines (12, 13) running through the piston, which move the piston (20) by pulling the control lines, and means attached to the spinnaker control apparatus for altering the length of the pole (8) or for lowering/raising its outermost end.
Apparatus according to 7, characterized in that, a cup (11) is attached at the outermost end of the pole and a satellite and loop (9, 10) are attached to the control line (12, 13) the loop being attachable to both the guy and the sheet (6, 7) of the sail.
Apparatus according to 7, characterized in that the fixed stop (14) is a bead-like component permanently attached to the control line.
Apparatus according to 7, characterized in that the two telescoping pole parts (17, 18) are further connected to each other by a spring (19) for shortening the pole by the force of the spring in an unloaded state.
