Dave, I take it that your boat is stored on dry land?
If so is there water lying inside the hull that could permeate through to the gel coat.

The main issue would seem to be a cosmetic one, if the area is small then you could remove the gel coat and re-apply it. We had a repair for a similar problem done on our sidedecks.
Or you could just leave it.

I am inclined to suggest that you need to dry the hull out – rather than trap moisture inside by applying wax.
