I'm pretty sure it has the wide bottom on it, so likely the 16'x54" model. The metal on the boat seems awfully damn heavy to me though, you could hit this thing with a sledge on the side and it wouldn't phase the beast. It is way too much boat really for what I am doing. You guys may be onto something with the balance idea. I always make sure the boat levels left to right but seldom worry about the bow to stern. Still, this boat is damn hard to move! Thank you very much guys for the comments.
