The Ger/BB/1916 redone

Another related drawing from September 9, 2001, was for a Ger/BB/1916 battleship design. It was related to the last, except with heavier armament. I think that the original concept may have been for 9-18in/45 guns, but by 2001, I had assumed that the armament would be 9-20in/45 guns with the 16 secondary guns which I still think were to be 5in QF guns. Springsharp allowed the design, as originally entered. The steadiness is suspect, but otherwise, the design seems to work. This is the Springsharp report:
