The reason I asked is possible rusting of internal shroud anchors...but it looks too low for that anyway...
No core, and the gash is actually on the bottom more than the side. The interior picture is inside one of the bench compartments in the cabin.
1) Have you any fiber glassing experience at all?
A little, meaning I've put down glass and mixed resin once.
2) Are you willing to learn and read a book about it?
I've never been afraid to try something new, and hey, since I got the hull for free whats the worse I could do, make it not seaworthy?
4) Follow advice of SYM and do some exploring of the surrounding area with a hammer tapping lightly on the hull to find solid glass...you are looking to isolate the mushy sounding thud of damaged glass to the solid higher pitched knock of good glass..This will be a good indication of your damaged area...of course you will be feathering back farther into good glass, but this will tell you within a couple minutes if the whole side of the boat is fractured or if its limited to what we see in the photos..
Thanks for the adivce. Both of you.
