That’s the damage. I’m hoping that I don’t need to take the finbox out, and can just cut out the surrounding fiberglass and re-glass it but im hoping for some input. Is there something I should look for regarding whether or not I need to take the box out and replace it?
I would attempt to get the box out. Cut around and down on the box with a Stanley knife. Secure a fin in the box and see if you can wiggle it loose and out. Clean up the hole and reinstall the box using filler. I would use milled fiber. I wouldn’t cut too much of the damaged glass away around the box. Just the loose stuff. Do a little q-cell cosmetic treatment around the edge of the box. Put a couple of football patches of cloth and resin over the box. Hot coat and sand. It will obviously not be as strong if you don’t remove the box and reinstall it. Which means you could just clean up and fill around the box and cover with cloth. The problem with that is that if you ever hit it again it would most likely get knocked out.
