Looking good Brian. How many floats are you going with?
6 floats per 12x12, and one on each gangway.
Five-3'x4'x16" and one-4'x4'x16" where gangway attaches
Each gangway float is 2'x4'X20", having different height on gangway float worries me some, but that is what they suggested. I'll know this weekend.
