Here we peel boats only to fix osmosis problems so, was that the case?

How would I know? It was years ago. It's possible, but it's also
possible that the gelcoat was peeled in excessnzeal.

In any event, the fiberglass of the hull is perfectly sound and shows
not the slightest trace of osmosis. You can see the surface quite well
in many of our boatyard pictures; and also see most of the stages of our
application of a new barrier coat.

Why are you so worried about it? I suggest you read
