YIKES 1979 20ft seacraft HELP PLEASE

[Will Work For Boats]

Thanks for the input. Sadly I cut the tops off and discarded them. I'm kicking myself pretty hard for it now. So now I was thinking of taking my glass and cutting it just wide enough and laying it on a piece of cardboard and wax paper then just making the cap like that and then laying the cap on the stringers and reglass it to the stringers. I already used 2 lb foam in the one stringer so I will be using 2lb.
