My Ger/CB/1943 design from March 1999

I have this sketch design for a large, fast battlecruiser that I am calling the Ger/CB/1943 that dates from March 1999. I have a ballpoint ink drawing, not to scale, and a few specifications. The main thing that I do not like about it is that the draft is too deep, at 40ft. I approve of it otherwise and it works extremely well in Springsharp 3.0b1 Beta. This is a 1,250ft ship with 9-21in guns that has a speed of 35 knots. This is the Springsharp report:
