This is a new version of the Ger/CB/1905 battlecruiser design. The design has a flush deck and two funnels. The armament has superfiring turrets for the 8-12in/45 guns. I was not able to reach 27.7 knots without further reductions in machinery weight and increase in power. These are originally planned weights:
- Hull=7,620 tons
- Machinery=2,280 tons
- Auxiliary machinery=720 tons
- Armament=1,216 tons
- Protection=7,284 tons
- Miscellaneous=1,600 tons

Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
31,426 lbs / 14,255 Kg = 36.4 x 12.0 " / 305 mm shells or 5.2 torpedoes
Stability (Unstable if below 1.00): 1.12
Metacentric height 5.7 ft / 1.7 m
Roll period: 16.6 seconds
Steadiness - As gun platform (Average = 50 %): 59 %
- Recoil effect (Restricted arc if above 1.00): 0.50
Seaboat quality (Average = 1.00): 1.18
Hull form characteristics:
Hull has a flush deck
Block coefficient: 0.550
Length to Beam Ratio: 5.96 : 1
'Natural speed' for length: 23.66 kts
Power going to wave formation at top speed: 55 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): 0.00 degrees
Stern overhang: 0.00 ft / 0.00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 28.00 ft / 8.53 m
- Forecastle (20 %): 22.00 ft / 6.71 m
- Mid (50 %): 22.00 ft / 6.71 m
- Quarterdeck (15 %): 22.00 ft / 6.71 m
- Stern: 22.00 ft / 6.71 m
- Average freeboard: 22.48 ft / 6.85 m
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 95.2 %
- Above water (accommodation/working, high = better): 173.5 %
Waterplane Area: 36,731 Square feet or 3,412 Square metres
Displacement factor (Displacement / loading): 103 %
Structure weight / hull surface area: 165 lbs/sq ft or 808 Kg/sq metre
