Perfect for spinnaker sheet turning blocks. This Ronstan block is free wheeling at low wind velocity. As the wind velocity increases the pressure on the sheave automatically engages the ratchet. The sheet rope is never trapped in the sheave and can slide out the same as any other ratchet block without first pulling in and then releasing. 55mm sheave.

  • Automatic and Manual ratchet in one!
  • 20:1 holding power
  • Easily fitted and securely retained
  • Stainless swivel shackle
  • Smooth easing of sheets

    Exceptional feel and top notch durability!

    I really like this mainsheet block for my laser. It has exceptional feel and I find it is superior to the ratchet blocks from the main competitors. Sometimes my coach will ask me to switch boats with a training parter during a training session, and the different ratchet block is the thing which I notice the most because I find I am not able to have the same precision with other blocks
