The Harken 75 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 75 mm Carbo Ratchamatic is as
high as 15:1.
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.
