ABSTRACT:
PCT No. PCT/SE78/00051 Sec. 371 Date July 9, 1979 Sec. 102(e) Date July 9, 1979 PCT Filed Oct. 5, 1978 PCT Pub. No. WO79/00272 PCT Pub. Date May 17, 1979
A device for simplifying the setting and taking in of spinnakers comprises a helix (7) which can be longitudinally expanded to a length corresponding to the length of the sail (1). One end of the helix is fastened in the running rigging of the boat adjacent to the head of the sail. A downhaul pulls the helix down over the sail such that the helix is successively stretched out to embrace the sail, and an uphaul is also provided for recontracting the helix from the expanded condition in order to release the sail.
