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.

Method in connection with the spinnaker pole (8) or similar of a sailing boat in a system, in which a control line (12, 13) is attached to both the sheet (6) and the guy (7) of the sail (4), the control lines (12, 13) being arranged to travel through the pole (8), characterized in that the control lines are arranged to move a piston (20) and that the piston (20) is connected to means, with the aid of which the length of the pole (8) can be altered, or the outer end of the pole can be lowered to the lower position.
Apparatus in a system in connection with the spinnaker pole (8) or similar of a sailing boat, in which a control line (12, 13) is attached to both the sheet (6) and the guy (7) of the sail (4), characterized in that the apparatus comprises a piston (20) moved inside the pole (8) 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 it for altering the length of the pole (8) or lowering/raising its end.
