Harken Carbo Ratchamatic Cheek Block



This 57 mm Carbo Ratchamatic Cheek Block is reversible so it can go on either the port or the starboard side. This block is used on the new racing Flying Scots for the internal spinnaker sheet blocks, mounted under the seat.

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.
