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.
Harken’s standard 10:1 ratchet (100 lb of force requires only 10 lb of holding power) is a great choice for medium or light-air days where it is vital to ease and trim the sheet smoothly and often. This ratchet is friendly to any type of line.
The 1.5x ratchet has a holding power of 15:1, or 1.5 times that of the standard ratchet. Use in breezy, puffy conditions to boost holding power and ease quickly when a puff hits. Depending on line composition and cover texture, the more aggressive sheave facets can increase line wear.
