And you do want at least a small gap between the plywood platform & the existing hull at the edge and where the plywood rests on the lip around the boat's perimeter.

I'm sure they're fine the way they are but the cardboard is free and i want to make sure i get it as good as i can. i can always grind off a little plywood if i have to. its easier to take off than add to it. No i have not ordered any of the fiberglass material. i am not sure when I'll be able to do any actual glass work. here lately Ive been working 630-5 Monday through Saturday. my new job starts Monday. its Monday through Friday and 7-3 so ill have plenty of time and daylight to get some work done. just have to wait on mother nature to turn the heater on. i plan on waiting before i get my resin so i get a good fresh batch and don't have it sitting around. i have been using 36 grit discs to knock the gel coat off. i have noticed that Ive been eating some glass with it too, so i am gonna try a 50 grit and see if that helps me.

well hit a roadblock earlier.... while grinding some gel coat off i sanded through the glass and down to bare wood. luckily i did cause i discovered a rotten floor. so my project just got a little bigger.

In order for the new glass to properly adhere to the old glass you need to grind into the old glass just a bit. Sorry to hear about the rotten stringers. It is typical of boats of this vintage. I'd advise you to drill into the transom as well to verify that it's ok. If the stringer is bad the transom usually is too.

Normally when the foam is wet, the stringers are rotten. I read earlier that you had some wet foam but the stringers looked okay. That is never the case, normally. Thankfully you found this now and not after it was all done. You will likely have to replace them from the front to back. But you will have a stronger, well built boat that, if done properly, will outlast your use. Good luck.
