Here is a link to pictures of the crack. The first are of a crack that opened up the 2nd to last is of some stress cracks that will eventually end up the same way if I don’t take some preventative action.
thanks in advance for any input

Aloha Rick - looks like your cracks developed along the stringer from compression of the foam next to the stringer and some good old fashioned foot/knee pressure. As long as they’re dry inside, you shouldn’t have too much of a problem. Couple different ways to approach it - depending on how deep the foam is pressed down. It doesn’t look like it’s pressed down too far, so what i would do would be to sand down the area where the crack is, including an inch or two all 'round. Do make sure you get the area where the glass has been pressed down sanded as well or you will have adhesion problems. Go easy, as you can quickly sand down into the stringer if you are concentrating on the fact that the compressed glass is below the level of the stringer. Once sanded, you can lay up several layers of glass to bring yourself back up to level. Sand flush (or relatively - you prob. won’t notice), gloss and polish if you want, and you’re good to go.
Now if your glass is decently compressed into the foam, you might have to add some filler to the depression once you’ve sanded, to minimize the layers of glass needed. Be careful to sand your filler back down to a level where you can add glass on top without sanding it all back off when you’re finishing.
Good luck!
