Seeing it could help identify WHY it came off, which is usually germane to fixing it, any competent repair shop would also SEE it before giving you an estimate of whats needed. And then at best its still an estimate until its completely repaired, hence the use of an estimate for repair.
IMO, w not pix, you are seeing the fiberglassed hull missing only gelcoat.
Its a skiff for shallow water, sandy shoals and beaching, easy to expect some gelcoat wear.
I would probably have addressed the repair sufficently prior to purchase.
FYI, collectively the members here have forgotten more then I'll ever know about fiberglass repairs, some members have extensive working histories dealing w all facets of fiberglass from pre-production, thru manufacturing and on to makor repairs of owner damage and manufacturing defects.
If they asked for pix, and you want their help, I'd try to provide a pix or 3.
