Harken 75mm Ratchamatic Block – Swivel, 2x Grip
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 allow sailors to fine-tune their set-ups in tandem with the purchase that provides the ideal level of power, responsiveness and grip.
The Carbo 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. 2x grip: breeze–on/puffs; 30:1 holding power
