HARKEN 2634

Double Carbo Ratchamatic® Block - 57mm

The Carbo Ratchmatic® 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 holding power of the 57mm is as high as 10:1.

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

Use for:

Main / jib sheets
Asymmetric spinnakers
