Sounds like you've got some good advice so far, I'll just add a couple of things. As Hermco said, let dry really well. Don't be in too big a hurry, you only want to do this once.

After drying, I would use a liquid foam and blow it into the void. As it cures it will expand and fill all the air spaces. This is not structural but it will give you the backing that you need with the least amount of effort. Once cured, you can shape the foam back with a knife and begin laying your glass. Sand and wipe w/ acetone inside there before applying the foam so you'll get good adhesion.

You talked to West System so you know about the tapering. In this case I would start with my biggest piece of glass first and then do progressively smaller pieces building outward.

A couple tips:

- Use West System epoxy
- Add a small amount of Cabosil to the Epoxy mixture when you initially wet out the boat. Give it time to become tacky before applying the glass. The cabosil in the resin makes it hold the glass up there better for some reason. This is especially critical as you'll be working upside down. When it's nice and tacky, apply the glass and wet out.

-If you want to apply multiple layers at one time you can use a vacuum bag. This is a great way to do repairs to the bottom because it not only holds the glass to the bottom but leaves a much smoother finish, ie; less sanding!

Any repairs to the bottom are tough but not impossible. Be sure to cover up, head too. Epoxy is hard to get out of your hair.

Good luck.
