Talk about extreme ships: GB/CB/1921d

I am looking at a version of a British 1921-style small battlecruiser that I designed in 2002. A feature of it is the extreme speed attained: 37 knots. To achieve it, the armament is just 9-10in/50, 12-5.5in/50, and 6-4.7in AA and the belt is 5in.
The specs are:
D=24, 500 tons
LWL=835ft
B=82ft
d=25ft
Cp=0.5445
Cm=0.92
V=37 knots
Belt=5in
SHP=215,000
The key to my abbreviations is:
Cp=prismatic coefficient
Cm=midship coefficient
LWL = length on the waterline
B=Beam
d=draft
D=displacement
V=speed
SHP = shaft horsepower
