I have plans for building a catamaran and it says that 4mm and 12mm gaboon ply is required. these sheets run about $46 and $94 a sheet. I was wondering if i could just use douglas fir 1/4inch exterior ply wood or some other type of construction grade material. Anyone try this before??

Rule #1 with multihullís is keep it light. BS 1088 Okoume is about as good as you get for low weight and high strength. You are probably going to spend a fair bit of time and money on the project anyway, so why cheep out on the basics?
