The Ger/CB/1915 from page 5 of the Red book

The Ger/CB/1915 design from the Red book, wanted to achieve 40 knots, but I could only reasonably obtain 34 knots, to obtain about the same amount of protection. The speed was perdicated on a mistaken speed-power calculation from the early 1970's. The specifications were more complete in this case:

Ger/CB/1915
Length=   900ft
Beam=     100ft
Hull Depth=58ft
Draft=     29.7ft

displacement (full load)=40,000 tons

Power= 216,000 SHP

3,620 tons of fuel oil

40,000 tons full load
 3,620 tons fuel oil
   543 tons feed water
35,837 tons standard
12,528 tons hull
 7,200 tons machinery
 2,875 tons armament
 8,974 tons protection
 2,860 tons miscellaneous
 1,400 tons auxiliary machinery

Overall survivability and seakeeping ability:
 Survivability (Non-critical penetrating hits needed to sink ship):
   44,978 lbs / 20,402 Kg = 20.0 x 16.5 " / 419 mm shells or 5.4 torpedoes
 Stability (Unstable if below 1.00): 1.30
 Metacentric height 8.0 ft / 2.4 m
 Roll period: 14.9 seconds

   - Recoil effect (Restricted arc if above 1.00): 0.54
 Seaboat quality  (Average = 1.00): 1.17

Hull form characteristics:
 Hull has rise forward of midbreak
 Block coefficient: 0.501
 Length to Beam Ratio: 9.00 : 1
 'Natural speed' for length: 30.00 kts

    - Stern:  18.00 ft / 5.49 m
    - Average freeboard: 23.84 ft / 7.27 m
 Ship tends to be wet forward

Ship space, strength and comments:
 Space - Hull below water (magazines/engines, low = better): 125.1 %
  - Above water (accommodation/working, high = better): 198.9 %
 Waterplane Area: 60,047 Square feet or 5,579 Square metres
 Displacement factor (Displacement / loading): 100 %
 Structure weight / hull surface area: 193 lbs/sq ft or 942 Kg/sq metre
 Hull strength (Relative):
  - Cross-sectional: 0.99
  - Longitudinal: 1.09
  - Overall: 1.00
 Hull space for machinery, storage, compartmentation is cramped
 Room for accommodation and workspaces is excellent
