I assume your "four plus years" is meant to be "four plus decades" and I assume you're talking about the delamination of the cored deck. The hull should be solid fiberglass for a boat of that vintage and no hull delamination would be expected or acceptable. Actually the deck delamination is more often a cosmetic than a structural problem; however, still something to be tended to. My 1973 Morgan has exhibited several "soft spots" from water intrusion and subsequent delamination of the balsa cored deck. At these spots I removed the top layer of the deck with a cutting wheel on a rotary tool (about 2 square feet) and removed the soft water damaged balsa core. In this area I laid a new sheet of balsa "tiles" matted on a fiber matrix. These approx. 1" square balsa sheets that I used were purchased from a Hunter dealer, but I'm sure you can find a comparable generic source. The advantage of the small tiles is that each piece will be surrounded by resin and prevent the spread of any furture water intrusion. I ground the balsa down so that it was 1/4" beneath the deck surface and then ground an extended slope into the adjacent deck to allow for maximum adherance of the patch. After carefully adding on overlapping layers of glass cloth impregnated with resin and rolling out any bubbles I ground the finished surface to match the surrounding deck. Since my non-skid is formed from quartz sand addied to a topsides paint, I had no difficulty making a uniform appearing patch that conforms to the rest of the deck. A patterned non-skid would require additional skill.
Back to the original question, if my assumptions were correct, a few delamination spots on an old boat should not discourage a purchase, 'take care and joy, Aythya crew
