Installing a new (larger) switch panel this weekend and I need to enlarge the hole where the existing panel is located. We don't have power at our dock so I will be cutting the fiberglass by hand.
I do not pay the extra dough for electricity at my finger slip but when I was installing a new switch panel, I used my battery operated Dremel. I believe I had to come back another day to finish up the job after recharging the Dremel but it worked great. Believe I used it with a diamond wheel cutter. I always have my tool bag for my boat in my car and the Dremel has a permanent home in that tool bag. I have used that Dremel many times for various projects, drilling holes, etc.
If you have a battery operated drill you can get a cutting wheel for it. Weather you can get it into a gutting position may be an issue. I have used a single hacksaw blade mounted in a handle. I do not remember where I found the handle. The blade sticks out about 4 inches to cut with.

Life is not a dress rehearsal. You will not get another chance.
I second the hack saw recommendation. Glass is a little too tough to cut with a blade made for wood. I've used a hacksaw and a wood file when working by hand and both work well. The wood file can be a little too aggressive sometimes. A good course metal file works as well. The file saves a lot sanding.
