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.
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.
