Post subject:  Stress Crack?
I'm a little embarrassed to post this since its probably my fault but I was just wondering if this crack is anything to worry about? It almost seems like a scratch but its right around where I had ratchet straps going over the hull to secure it on the trailer which makes me worried it might be a stress crack? Its about 4 inches long and starts along the aft pylon. I could swear I've always left plenty of slack in the straps but maybe not, especially since the deck seems crushed as well. What would be the best way to repair the crack since it doesn't seem to be very deep? ...I included the link since displaying the photo isn't working for me

Yep. That's a stress crack from over-tightening over-the-hull straps.

The other part (that looks "crushed") looks like chafe from a fluttering strap.

Neither are much more than cosmetic. If you want to fix the crack, use something (like a can opener) to notch it out and fill it with thickened gel coat.

And stop using over-the hull straps!

Thanks! The straps came off right away!

You should either run the straps fore/aft so they go over the crossbars or run four individual straps/ropes around each pylon or corner casting so you don't put a concentrated load on the deck. That crack looks pretty minor, but I would press down and knock on the hull in that area just to be sure there's no delamination.
