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 our freely during mark roundings and asymmetrical spinnakers free instantly during jibes. Ratchet engagements may be adjusted to higher or lower load according to strength and sailing style. The Ratchamatic cheek blocks mounts on either port or starboard. Holding power of the 75mm is up to 15:1.
