I fell on my board harness hook first. Put a crack in it right where I put my foot into the straps. I have attached a few pictures.

Couple of questions
- I was planning on filling it with this epoxy filler - one called "marine tex"
- Any advice on the size of area I should apply it? I was thinking one big patch that extends 2 inches past the crack on every direction
- Then I might put a fiberglass coat on top of that
- Do you think this repair will hold? Especially with the fact that this is where I put my front foot on the board?

I'm buying a new board soon, but I'd love to keep this board for light wind days and a big sail. Any advice is appreciated!
