Mainsheet Ratchet Block - Ronstan Gold

Uses: ILCA and Optimist Mainsheet blocks.

The Ronstan ratchet block features both automatic and manual ratchet options, and boasts an impressive 20:1 holding power ensuring you never lose grip of the main sheet. Using the adjustable ratchet feature, you can also turn the ratchet off for lighter wind down winds, to help improve feel for the mainsheet, and keep the sail accurately trimmed at all times. 

With Ronstan's soft attach system, the block is unable to twist in circles, which helps avoid getting your mainsheet tangled.
