Harken's Carbo Ratchamatic® Blocks are load-sensing blocks that roll freely in both directions under low loads and automatically engage the ratchet as loads increase, making shifting between ratchet and light-air modes 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 57mm Ratchamatic® provides up to a 10:1 holding power.


The patented switch locks shackle in front or side positions, or lets block swivel to keep line from twisting. The eight-faceted, hard lube-anodizing aluminum sheave holds line securely.
