I was experimenting with a Hood-like ship

I wondered how my power calculation program would do with a ship like the Hood. I don't know the coefficients for the Hood, so I had to guess. These are my results:

Displacement=42200.0 tons
Length=850.0ft
Beam=104.0ft
Draft=30.0641ft
Cp=0.585
Cm=0.95
Cb=0.55575
Hull Weight=13392.6 tons
Displacement=42200.0 tons
DLR=68.7156
Wetted Surface=95826.5
B/H=3.45927
