I am going to trim some plywood frames that intersect the hull right at
the
shoulder position of a few quarterberths. These are either 1/4" or 3/8"
plywood frames, tabbed both sides to the hull. By the

Just a thought. If these plywood frames were installed using good
fiberglass/marine practices, the would be a strip of foam between the edge
of the ply and the hull. Among other thing, it also forms fillet for the
tabbing. If your lucky and the builder put this foam strip in, then you can
just grind the glass down with the edge of a cutting wheel, until you get to
the foam, same on the other side. Cut ply perpendicular to the this kerf and
break it off in sections.

Good luck.
