Load-sensitive ratchet engages automatically when the sheet is loaded (Fig. 1) and disengages when the load is released for smooth, free running in tacks and gybes (Fig. 2). Precision CNC machined alloy sheave provides up to 14:1 holding power, yet minimises rope wear for extended sheet life. Unique adjustment mechanism allows the engagement load to be set precisely as required. Higher setting keeps the ratchet off for light air sailing or until the sheet load increases. Lower setting will trigger the ratchet at a lower sheet load. Ratchet engagement setting can also be varied to suit the load felt in your hand, so that younger sailors can set the engagement at a lower load to match their strength.
