Another "super ship": US/BB/1936
I drew a picture dated June 13, 2001 depicting a very large battleship with a sort of US look to it. I scaled off that picture and used the specs to enter into Springsharp. The main change that I had to make was to lower the freeboard, as what I had drawn was excessive. The result is a very capable ship. It is all that I would want in a very large battleship:
