Block, Single Ratchamatic Carbo Air 57mm MaxLine: 10mm with Swivel

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 roundings and asymmetrical spinnakers free instantly during jibes. Ratchet engagement is adjustable to a higher or lower load according to strength and sailing style.
