Stretching the limits with another version of the Ger/CB/1942

There is a longer version of the Ger/CB/1942. I had to accept a 40ft draft, which is ridiculous, but the design can make 37 knots, with a 15 knot cruising speed. This is with a rather thin 12in belt. The specification in the book was:

CB
120,000 tons      Cp=0.57    9-21in/45
Length=1,250 ft   Cm=0.92
Beam=    158 ft
Draft=    40ft
Speed= 35 knots (the design was good for 37 knots)

The advantage to large, fast ships is that they can outrun (or run down) small fast ships in any sort of seaway, at all. This is the Springsharp report:
