The Carbo Ratchamatic Power3 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. Ratchamatic blocks are now available in three different holding powers.
Power3 ratchet blocks have one-design sailors covered with three holding-power options that best suit the day’s wind and wave conditions. More ratchet choices allow sailors to fine-tune their set-ups in tandem with the purchase that provides the ideal level of power, responsiveness, and grip.
