The Blocker-Roller® textile blocker is an adjustable, self-locking estrope with a low-friction ring, or an open ring for hooking your headsail sheets.

  • Three times lighter and twice as strong as a conventional metal blocker, the Blocker-Roller® textile blocker can be used to create a furler, a barber-haufer that can be easily installed on a chainplate or rail,...
  • Simple and effective, this blocking system uses the textile sock principle: the greater the tension, the stronger the blocking.
  • Installation and use is simple and requires no drilling in the boat. The blocker is attached with a shackle or snap shackle directly to an existing chainplate, fargue rail, trigger guard, etc.

+ Use

1- Connect the Blocker-Roller to your deck with our "Bosco" textile shackle.

2- Adjust the power of your genoa:

  • By increasing the length of the Blocker-Roller® boom, you raise the clew, which opens the sail and the power comes out the top.
  • Decreasing the length of the Blocker-Roller® boom closes the leech, increasing power and heel.
