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. 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 75 mm is up to 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.
