Re: Aluminum Starcraft , new wood floor, glass in or not?
Guys the fiberglas adds not only waterproofing, but strength. If you don't want to be re-flooring that boat in a short time, spend the little extra and do one ply of glass re-inforced epoxy resin on the top. This will also protect the wood from misc damage from equipment droppage, sharp edges, etc.
Not tryin to flame anyone here, but folks are always tryin to re-invent the wheel on this subject. For the money, the best approach would be 1/2" marine grade douglas fir (5 ply) made with the highest grade waterproof glue. Epoxy resin bottom and sides with at least one coat, two or three if you can, and one ply of glass mat and epoxy resin with another coat of epoxy resin over that. Then you can paint, vinyl, whatever. With this approach you have strength, not too much weight, and you won't be taking it all up in a couple of years.
I just picked the LL up at the boat mechanic's today. 5 mins into the trip home and downpour. Everything in the boat was totally saturated by the time i got it home and I'm not worried about my deck one bit.
Also the aluminum will flex too much to try and glass up and onto the sides. End your mat at the edge and it's done.
