I've used a reciprocating saw to cut both fiberglass or steel in similar
situations.

The good quality long blade will flex enough to allow you the clearance you
need for the saw against the hull. It is however, hard on the saw since it
causes a side thrust that it is not built for. The cheap saws have only alum
or plastic guides that wear quickly.

Blades will also dull quickly, what ever method, because of the glass
fiber...I a long cut in 1/8-3/16" material I have seen the teeth wear
completely off in a foot or so. Not a cheap project when blades cost $2
each.

I am going to trim some plywood frames that intersect the hull right at

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.

Fein Multimaster has a cutting blade attachment that can plunge cut.

plywood frames, tabbed both sides to the hull. By the way, I'm a naval
architect and mech. engineer so I have a pretty good idea of what I can
and
cannot cut

I can cut down into the glass with a jigsaw, but the baseplate of the
jigsaw
will bump the hull before I get close enough - and I would like to run the
cut line right down the hull for about 12".

So the tools I have available a

- angle grinder with cut-off wheel
- dremel tool with fiberglass cutting discs
- jigsaw

Any other tools that might work for a tight cut against the hull through
fiberglass tabbing? The only other one I can think of is a reciprocating
saw ("Sawz-All") but they are a bit hard to control and still get a nice
close to the hull.

I recognize I'll have to do some grinding / sanding of the last of the
tabbing but would like to minimize the amount of this.
