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!!!
