The Harken 2165 57mm swivel Ratchamatic block is part of the Power3 range, which offers sailors racing small one-designs three holding-power options for varying 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.
