Misc Weight is 2x cranes

Main battery barbettes are averaged somehow I didn't do the math because I don't want to.
Main belt is 9' above the waterline, covering half of aft freeboard height, and 6' below waterline.
Deck consists of a 1" weather deck and a 5" main armored deck joined to the top of the main belt 9' above waterline.
Compliant with the Washington Naval treaty! And it fits in the Panama canal!
