Wieżowy pancernik obrony wybrzeża

Coś mi się zdaje, że jest oczekiwanie na coś konkretniejszego, i to koniecznie bez żagli;-) Zatem prezentuję pierwszą przymiarkę do nowoczesnego pancernika wieżowego:

    Bunker at max displacement = 212 tons (100% coal)

Complement:
    214 - 279

    £0,299 million / $1,195 million

Distribution of weights at normal displacement:
    Armament: 139 tons, 4,3%
    Armour: 1 093 tons, 33,7%
       - Belts: 528 tons, 16,2%
       - Torpedo bulkhead: 0 tons, 0,0%
       - Armament: 388 tons, 12,0%
       - Armour Deck: 149 tons, 4,6%
       - Conning Tower: 28 tons, 0,9%
    Machinery: 544 tons, 16,7%
    Hull, fittings & equipment: 1 245 tons, 38,3%
    Fuel, ammunition & stores: 226 tons, 7,0%
    Miscellaneous weights: 0 tons, 0,0%

Overall survivability and seakeeping ability:
    Survivability (Non-critical penetrating hits needed to sink ship):
      2 267 lbs / 1 028 Kg = 8,1 x 9,0 " / 229 mm shells or 0,7 torpedoes
    Stability (Unstable if below 1.00): 1,06
    Metacentric height 1,8 ft / 0,5 m
    Roll period: 14,6 seconds
    Steadiness    - As gun platform (Average = 50 %): 54 %
            - Recoil effect (Restricted arc if above 1.00): 0,34
    Seaboat quality  (Average = 1.00): 1,08

Hull form characteristics:
    Hull has a flush deck
    Block coefficient: 0,656
    Length to Beam Ratio: 4,93 : 1
    'Natural speed' for length: 15,14 kts
    Power going to wave formation at top speed: 49 %
    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:        7,97 ft / 2,43 m
       - Forecastle (26%):    7,48 ft / 2,28 m
       - Mid (50%):        7,48 ft / 2,28 m
       - Quarterdeck (25%):    7,48 ft / 2,28 m
       - Stern:        7,48 ft / 2,28 m
       - Average freeboard:    7,53 ft / 2,30 m
    Ship tends to be wet forward

Ship space, strength and comments:
    Space    - Hull below water (magazines/engines, low = better): 86,2%
        - Above water (accommodation/working, high = better): 54,6%
    Waterplane Area: 8 201 Square feet or 762 Square metres
    Displacement factor (Displacement / loading): 98%
    Structure weight / hull surface area: 112 lbs/sq ft or 545 Kg/sq metre
    Hull strength (Relative):
        - Cross-sectional: 0,92
        - Longitudinal: 2,03
        - Overall: 1,00
    Hull space for machinery, storage, compartmentation is adequate
    Room for accommodation and workspaces is cramped
