I'm doing a bunch of projects including replacing and/or re-locating all the thru-hulls and seacocks. I have one I'll be removing althougether (head direct overboard discharge) and at least one more that will get moved (head seawater intake). How do it plug the holes in the hull? It's solid glass, I think about 1/4" thick. Of course I'll put major fiberglass patches inside and out (planing to use West System), but what do I use to fill the void where the between the patches (i.e. the thickness of the hull)? The largest will be about 1.5" in diamter and 1/4" thick. I could make a fiberglass board the appropriate thickness with epoxy and glass, then cut disks from it to put in the void. Or use marine plywood. Or just thickened epoxy. Any thoughts or suggestions?
Too many thru-hulls

Yep, that's a valuable repair technique too.
It involves grinding the surround hull in a very shallow funnel shape. Something like 5 to 10 to one. Then filling with succeeding larger layers of glass roving. Many boat repair books have photo articles and so do the vendors of the tools, like West System. Score one of their books.

pucks/disks
One option is to pour thickened epoxy into a plastic container that is the same size as the hole. Basically a hockey puck that just fits the diameter of the hole. Don't make it the same thickness of the hull though. Make it thinner and then build up on both sides. Good luck. Don Casey's book is pretty good.
