An expansive version of the Ger/BB/1907 design

My version of the Ger/BB/1907 design that is "pushing the envelople" must have dated from 1973. I was trying to get the most performance out of designs, while in 1971, I was keeping more to moderate speeds and machinery weight. This version depends very much on lightweight machinery:

   - Armour deck: 3.00" / 76 mm, Conning tower: 13.00" / 330 mm

Machinery:
 Oil fired boilers, steam turbines, 
 Direct drive, 4 shafts, 138,274 shp / 103,152 Kw = 30.20 kts

 Armour: 8,798 tons, 32.0 %
    - Belts: 2,872 tons, 10.4 %
    - Torpedo bulkhead: 666 tons, 2.4 %
    - Armament: 2,438 tons, 8.9 %
    - Armour Deck: 2,566 tons, 9.3 %
    - Conning Tower: 255 tons, 0.9 %
 Machinery: 3,832 tons, 13.9 %

 Miscellaneous weights: 0 tons, 0.0 %

Overall survivability and seakeeping ability:
 Survivability (Non-critical penetrating hits needed to sink ship):
   49,807 lbs / 22,592 Kg = 57.6 x 12.0 " / 305 mm shells or 7.9 torpedoes
 Stability (Unstable if below 1.00): 1.14
 Metacentric height 6.9 ft / 2.1 m
 Roll period: 16.8 seconds
 Steadiness - As gun platform (Average = 50 %): 51 %
   - Recoil effect (Restricted arc if above 1.00): 0.38
 Seaboat quality  (Average = 1.00): 1.02

Hull form characteristics:
 Hull has a flush deck
 Block coefficient: 0.569
 Length to Beam Ratio: 5.90 : 1
 'Natural speed' for length: 24.90 kts
 Power going to wave formation at top speed: 61 %
 Trim (Max stability = 0, Max steadiness = 100): 50
 Bow angle (Positive = bow angles forward): -1.00 degrees
 Stern overhang: -2.00 ft / -0.61 m
 Freeboard (% = measuring location as a percentage of overall length):
    - Stem:  32.00 ft / 9.75 m
    - Forecastle (20 %): 30.00 ft / 9.14 m
    - Mid (67 %):  30.00 ft / 9.14 m
    - Quarterdeck (15 %): 22.00 ft / 6.71 m
    - Stern:  22.00 ft / 6.71 m
    - Average freeboard: 28.24 ft / 8.61 m

Ship space, strength and comments:
 Space - Hull below water (magazines/engines, low = better): 87.0 %
  - Above water (accommodation/working, high = better): 238.5 %
 Waterplane Area: 46,235 Square feet or 4,295 Square metres
