That is not always true, I chop nose of my 130L fanatic 3 times (at catapults) .
First was standard nose splitting and bleeding, then after repair with fiberglass I thought is was nondestructive.
So board just brake 20 cm below and across whole board this time then after solid repair next 5 cm lower again.
Now I think should be indestructible indeed. I broke 2 mast since then
and nose still standing.
Wow....just wow. You do also realise that the board is only as strong as it's weakest link? Which in this case is the section right adjacent to your repair? Hence why you strengthened it, it cracked behind it, you strengthened it again, it cracked behind it. It will snap off again behind your current repair if you hit it hard enough; you will require more force as the board is getting thicker, hence stronger as your repairs approach the mast :o
Given you have snapped the nose off 3 times and broken 2 masts it maybe time for a technique re-think? Just saying.

The only way it would ever work would be to have the section in front of the mast detach, as stated above, but man it would be messy I reckon; first big catapult and I reckon it would be goooooooooone. Boards are short these days, none of my current boards are >232cm long, at that length you can even fit them inside a Hyundai getz.
