Product Description

The Harken 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, the sheet runs freely during mark roundings and jibes. Ratchet engagement may be adjusted to a higher or lower load according to strength and sailing style. Holding power of 57 mm is as high as 10:1.
