Peter Harken first designed the now iconic six-sided Hexaratchet® block in 1971. With a 17:1 holding power ratio, this meant that the trimmer had only to exert one (1) pound of force to hold 17 pounds of load. This leverage provides much-needed relief when conditions are breezy. As Peter said, “(it) has made every ratchet block in existence obsolete including our old one.” Fast forward forty-six years and Harken Ratchet blocks are found aboard nearly every class of boat across the sport of sailing.
