In 2008 I have experienced a crash with my 11 MOD seven11.

Here is the story about the repair:

On starboard you can see the crack. This is the look from inside the hull.

First I had to cut everything out

Then skive the edges and put aluminum strips on the outside and wax them from inside.

Laminate 20 layers from inside

Smoothen the outside, grind a million times and apply YACHTCARE Antislip on the deck  - finish!!!
