Thanks for the input

I'm going to check it again. It's a beige color, shiny surface about 0.3mm
thick (it the thickness of a couple of layers of an oil based paint). Flakes
off just like dry paper, I could strip the inside of the hull in about 3
minutes with a screwdriver!

Funny that it's not on the starboard side though - that side is fine. I
wondered if it was a sign of inpact or something. As best I can tell the
hull has not been repaired at all. In fact, for a '78 it's a very clean
boat - much more presentable that many newer boats I've looked at. The guy
that owned it before apparently had it for some time and maintained it
rigorously. Sadly he passed away, but his legacy lives on I guess.

Cheers

There are a couple possibilities here.

It may not even be gel coat since the OEM may have just sprayed paint onto
the interior surface of the molded hull.. And the area you see flaking
didn't have the wax (surfacing agent) removed. This stuff is always
present
in the final resin applications of the layup process.

If it is gel coat resin, then the probable cause, again, is the OEM
neglected to clean the surface of this wax.

Odinary paint often flakes off interior glass surface, over time, due to
the
dampness of the glass surface or due to improper priming.

If the stuff that is coming off doesn't cantain any glass fibers, the I
don't see this as a structural problem.
