HarkenHarken 57 mm Carbo Ratchamatic? Block w/ Cam, Becket
Product Description

The Harken 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 may be adjusted to a higher or lower load according to strength and sailing style. The Harken Ratchamatic® cheek block mounts on either port or starboard. The holding power of the 57 mm is as high as 10:1.

For the ultimate system, mount a Harken Ratchamatic® on the boom above a cockpit-mounted switchable ratchet to allow the mainsheet to run freely in light air and to double holding power in heavy air.

Use for:
Main/Jib Sheets and Asymmetric spinnakers.
