Arrangement with sail boats for trimming and sheeting foresail - has two parallel lines attached to sail sheet corner and going via double block and further in common part to sheet winch

摘要

In parallel lines (7,8) is arranged a variator (11) for adjustment of the reciprocal length relationship for the lines and, the reciprocal force relationship between them, in form of trimming is controlled. The length/force variations for the lines are arranged in that the centre of a pulley forming part of the block, around which one of the lines runs, and is displaceable parallel with the centre of another pulley fro the other line. The variator comprises a double block with two pulleys pairs, each pair having two parallel pulleys, where one line is drawn over one pulley in a pair and under a pulley in the other pair, and the other line under the parallel pulley in the first pair, and over the parallel pulley in the second pair. The centre for the two pulley pairs are reciprocally turnable and/or displaceable in opposite directions for varying the force distribution in the lines.
