YIKES 1979 20ft seacraft HELP PLEASE

[Will Work For Boats]

It's a 1972 seacraft

ok I know I did way more damage here than good. I listened to people in other forums and they had no idea what I was working with. Started with a soft deck which I found to be two decks and I've was over layed on the other. So I ended up getting the entire boat and now I am down to a bare hull. Major paint issues also.

I fired the stringers which are solid foam. Ruffly twelve inches wide and about 11 ft long by six inches deep. People in other forms told me because the foam was wet to remove the foam. So I cut the tops of these massive stringers which were solid foam and zero wood. Now I'm putting the foam back in but this pour foam is no joke and you can't keep it flat.

So I have 17 oz fiberglass to put back on these stringer tops but should I do that and cut a relief in them every four feet four when I pour the foam. I'm using a 2lb. Also how do I keep the caps perfectly straight and flat, is 17 oz cloth enough?

Next in the original deck in the rear it had hooked down to the bottom of the boat I was assuming was for a wet deck. Should I leave these our what should I do here?

As you can imagine I'm going to have a ton of questions. I'm more than grateful to any and all input
