You may want to get a reputable fiberglass guy to look at the boat and give you an official opinion. Ron's Fiberglass USA is very good. Or have someone else with a moisture meter give you an opinion as to how cosmetic the issue is.

Your first concern should be "Is the boat safe?"!

If any underlying structural parts are at risk, soggy or rotted, then you are at risk.

If the fiberglass itself only has bubbles, then that can be mostly cosmetic.

I previously owned a 1995 boat that had cosmetic fiberglass bubbles, but the boat was safe.
