The fitting has a tubular arc segment (9) fixed to a tubular arc (10), which is slid into the arms (3) of the branched boom. The arc segment has an inward projecting flat surface (12), with a wide slot (13), in order to receive a fastening loop (14), or eye, on the clew (8) of the sail (7). The fitting also has an integrated snap-lock (16), which has a spring-loaded (21) swivelling hook (17) for swinging into and out of the loop. The arc segment may be made from injection-moulded plastic, and the arc and the hook may be made from aluminium. |
