Thanks Bill for the reply. I think I understand everything you've
mentioned.

Instead of laying new glass into the crack in stages (since I'll be
doing this upside down), would it be easier for me to use Marine-Tex
epoxy putty? I'd like to know if that would work just as well as
laying new fiberglass?

Thanks so much again.

The glass cloth is much stronger then simply applying putty as the
glass fibers oriented across the damage act to "tie" the undamaged
sections together..

I agree. It's a lot more work but it's worth the effort.

Okay, that makes sense.

Would it be even better for me to cut through that layer of fiberglass
that's above the floor in order to repair the damage from the
inside? If I can cut enough of the fiberglass out from that
elevated layer to access the floor, could I lay new glass from the
inside, and then also fill the crack from the outside using Marine
Tex?

The questions that you ask show that you have not done this kind of work
before.

What would be BEST is to find someone locally who has and get help.

Thanks Richard, but I plan on doing this myself. That's how I'll
learn, and that's why I'm asking the questions to better understand.
How else does anybody learn a skill?

There is the auto body repair class at the local community college.
Drag it to a friendly local boatyard and pay them to tell you how to
fix it Ask your local surveyor, not the one with the laser theodolite,
the one that checks out condition of boats. Maybe a helpful book
exists.

I talked to a mate who is in the business here in Phuket and he
suggests that you treat the repair much like repairing a hole in the
hull. Grind out the damage. Taper the hole back to original hull
thickness over a distance of say, four inches. He suggests using epoxy
to make the repair stronger. Lay in cloth until you built up the
damaged area to hull thickness. Fair roughly by grinding and then use
epoxy filler for final fairing. Sand fair, prime and paint.

He commented that you do need to analyze the problem to determine what
caused the original problem and possibly you may need to add some
reinforcement to prevent further cracking.
