Hello All:
We are in the process of purchasing a 1998 38 Ocean. Boat was hauled out and inspected during survey. Immediately after cleaning, blisters below the waterline were noticed. Probably numbering around 100 per side. No larger than about 21 mm (US nickel), nearly perfect roundness and random pattern. Immediate bottom had no blisters, limited to the sides and slightly down the curved chine.
Blisters were confirmed to be gel coat blisters and were dry inside (using moisture meter then peeling one off). Quite hard, could not depress blister with hard finger pressure. The surveyor said the blisters were "non-osmotic", dry, and did not have any particular odor (gassing).
All this said, the surveyor gave us a well rounded lesson on types of blisters and summed it up this way: Get a "worse case" repair quote to negotiate the purchase price. He also said that he wouldn't worry too much about them and most likely would not repair them if he were buying the boat. But, keep an eye on them to make sure they do not get larger.
We are comfortable with his opinion, he is reputable and has been a surveyor for many, many years. We are concerned about the potential resale value when we become the sellers.
Seeking thoughts, opinions and advise from anyone here!
