Now you can enjoy the flexibility of setting up your fitout exactly to suit yourself. Ronstan is the only company that offers a 40mm ratchet block with both auto and manual engagement models*
With automatic models, the ratchet mechanism engages when load is applied, but switches off when it's released. This lets the sheet run out smoothly and freely-great for rapid easing of the sheet and for gybing asymmetric spinnakers.
Manual modes allow the ratchet mechanism to be switched on or off as required. This is the preferred mainsheet set-up for many top sailors.
Up to 14:1 holding power - highest available!
