Never fabricated anything b4 so any help is very apreciated. I have a fiberglass tri-hull that I want to put a deck on. I really want to keep it flat and made out of aluminum. How would I go about braceing it and what size aluminum should I use? Also what would be the best way to attach it? And for the fellow ky guys where do I get the alum. I need? Can't seem to find anywhere around here (madisonville) when I google it.
