摘要

The sail sheet jamming-cleat for fixing to a sailboard wishbone boom is basically conventional, having two facing cheekpieces with internal inclined-bar projections arranged to cause the sheet to jam automatically under tension. These cheekpieces (1,2) are linked by a flexible strap (3), with an angled extension-strip (5) at one side to which a wedge (6) is fixed. The cheekpieces' undersides and the wedge sloping surface are corrugated. The entire assembly is made of synthetic material, in one piece.
