Now, let's design the cruiser analog to the "moderate dimensions" battleship

I have been experimenting with a battlecruiser analog to my "moderate dimensions" (for 1921) battleship. The battlecruiser has the same armament (9-15in/45 and 16-5.5in/50 guns) and can make 31 knots at normal load. The normal displacement is 30,237 tons (at the present), and has dimensions of 814ft x 95ft x 29.8ft. The coefficients are: Cp=0.53 and Cm=0.90. The armor basis is 9in. This is only a preliminary cut, as I haven't made a drawing, yet. Without a drawing, you can't be sure that everything will work.
