The reason I asked is possible rusting of internal shroud anchors...but it looks too low for that anyway...
1) Have you any fiber glassing experience at all?
2) Are you willing to learn and read a book about it?
3) It ain't rocket science
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..
