I took my old trusty die grinder and attacked the spot , as best as I could tell
after the dust settled , thinking its gel coat . So with that information
I'll leave it be for now . I'm living in the wet land of Vancouver
B.C. . Hoping to have this boat cleaned and fixed up to my
satisfaction for sailing by January

A 1/4" crack is DEEP. Could it be that the gelcoat that was used to paint
out the interior of the boat pooled in that area to a depth of 1/4"? Get
some light and dig around and you should be able to tell if it;s gel coat or
glass. There shouldn't be any filler material there; we simply prewet the
plywood and bonded one side, and when that cured we bonded the other side.
Bonds should be a bit wetter than a laminate but definately not wet enought
to be swimming in resin, which becomes brittle and dead weight.
I don't suppose you're anywhere near Sacramento?
