Harken 2165 57mm Ratchamatic Block with swivel and 1.5 times grip: breeze-on/puffs; 15:1 holding power.

Power3 ratchet blocks provide sailors that race small one-designs with three holding-power options to handle a variety of wind and sea conditions. More choices allows sailors to fine-tune their set-ups in tandem with the purchase that provides the ideal level of power, responsiveness and grip.

This 57mm Ratchamatic is a load-sensing ratchet block that rolls freely in both directions under low loads and automatically engages the ratchet as loads increase. Shifting between ratchet and light-air modes is seamless.
