The principle is simple: as the tension of your sheet increases, the blocking of the Blocker-Roller® strope increases.

+ Uses

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 the list.
