Black fixing rubber

The black stopwatch is fixed with the help of this part.

Tip:

1) It is very important that the svert does not slide up by itself or due to the waves. As long as you have to push back, you lose precious seconds when you should hang the boat out and lose altitude due to the slip.

2) The tighter fit of the svert in the boat reduces dead spots, which results in better speed and sharpness.

Better adhesion and grip can be achieved by placing two such svart fixing rubbers on top of each other at the same time and screwing them onto the boat.
