Harken 57 mm Ratchamatic Block — Swivel, 1.5x Grip
$122.95
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.
1.5x grip: breeze–on/puffs; 15:1 holding power.
