Harken 2680 75mm 3" Single Carbo Ratchamatic Block
HARKEN 2680
Single Carbo Ratchamatic® Block - 75mm
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 75mm is as high as 15:1.
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.
