My 1921-style light cruiser

I had done a 1921-style light cruiser with 9-6in/50 guns and 6-4.7in/50 AA guns, and when I did weight, stability, and volume analysis, the design worked. I had to resized engine rooms and boiler rooms, but I had allocated adequate space, at least when using a contemporary SHP/ton measure. I had allocated too much space to boilers and not enough to engines. The dimensions are 572ft x 54ft x 15.7ft at normal displacement. The coefficients are Cp=0.61 and Cm=0.90.
