57mm Harken Automatic Ratchet Block

The 57mm Harken T2 Ratchamatic is Harken’s newest block to feature the T2 line’s styling and soft-attachment system.

The weight of this high-strength block is only a few ounces.

Pressure on the line engages the ratchet mechanism, which switches seamlessly from free-running to ratchet mode. Unloaded main and jib sheets run out freely during mark roundings, and asymmetrical spinnaker sheets free instantly during jibes. T2 Ratchamatic blocks are clearly labeled with high-contrast directional markers for correct reeving and trimming direction.

Use for mainsheet and spinnaker systems on beachcats, dinghies, and sportboats.

A length of Spectra® line with a polyester cover is included.
