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. Unloaded main and jib sheets run out freely during mark rounding and asymmetrical spinnakers free instantly during jibes. The Ratchamatic cheek block mounts on either port or starboard.
Ratchet engagement may be adjusted to a higher or lower load according to strength and sailing style. The holding power of the 57mm bocks are up to 10:1.
