Harken Carbo Ratchamatic Blocks: 57 mmHarken


The Harken 57 mm Carbo Ratchamatic is a load-sending ratchet block that rolls freeling 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 Ratchamatic cheek block mounts on either port or starboard. The holding power of the Harken 57 mm Carbo Ratchamatic is as high as 10:1.

For the ultimate system, mount a 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 the HAR2634 with a HAR402 or HAR403 swivel arm for a versatile two-speed mainsheet system.
