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. When changing gears, the over-center shifting between ratchet and light air modes is crisp and seamless.

Unloaded main and jib sheets run out like greased lightning during mark roundings. Asymmetrical spinnakers that require the tough holding power of a ratchet, also free instantly to give you perfect, effortless jibes.

Moreover, how about this terrific feature - with the simple twist of an Allen wrench you can adjust ratchet engagement to a higher or lower load to suit your own muscle power or sailing style.

Great for main and jib sheets; also asymmetric spinnakers. 57mm sheave, 3/8 in. maximum line size.
