Nowe okręty podwodne

Dziś prezentuję nowy typ okrętu podwodnego.  Jest to rozwinięcie poprzedniego typu Tuńczyk z 1909 r. Nowa jednostka jest nieco większa, ma o 1 wyrzutnię torped więcej, i jako pierwszy okręt podwodny w naszej flocie posiada na wyposażeniu działko szybkostrzelne. Największy postęp dokonał się w dziedzinie osiąganej głębokości zanurzenia, bowiem zanurzenie operacyjne wynosi aż 51 m. Jak na 1911 r. jest to ścisła światowa czołówka, a kto wie, czy wręcz nie rekord świata :)

  Armament: 0 tons, 0,0%
    Armour: 1 tons, 0,1%
       - Belts: 0 tons, 0,0%
       - Torpedo bulkhead: 0 tons, 0,0%
       - Armament: 1 tons, 0,1%
       - Armour Deck: 0 tons, 0,0%
       - Conning Tower: 0 tons, 0,0%
    Machinery: 58 tons, 13,4%
    Hull, fittings & equipment: 173 tons, 39,6%

    Miscellaneous weights: 142 tons, 32,5%

Overall survivability and seakeeping ability:
    Survivability (Non-critical penetrating hits needed to sink ship):
      98 lbs / 45 Kg = 63,5 x 1,5 " / 37 mm shells or 0,2 torpedoes
    Stability (Unstable if below 1.00): 1,00
    Metacentric height 0,4 ft / 0,1 m
    Roll period: 12,5 seconds
    Steadiness    - As gun platform (Average = 50 %): 0 %
            - Recoil effect (Restricted arc if above 1.00): 0,00
    Seaboat quality  (Average = 1.00): 0,00

Hull form characteristics:
    Hull has a flush deck
    Block coefficient: 0,447
    Length to Beam Ratio: 8,60 : 1
    'Natural speed' for length: 12,82 kts
    Power going to wave formation at top speed: 53 %
    Trim (Max stability = 0, Max steadiness = 100): 32
    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:        0,00 ft / 0,00 m
       - Forecastle (20%):    0,00 ft / 0,00 m
       - Mid (50%):        0,00 ft / 0,00 m
       - Quarterdeck (15%):    0,00 ft / 0,00 m
       - Stern:        0,00 ft / 0,00 m
       - Average freeboard:    0,00 ft / 0,00 m
    Ship tends to be wet forward

Ship space, strength and comments:
    Space    - Hull below water (magazines/engines, low = better): 147,6%
        - Above water (accommodation/working, high = better): 0,0%
    Waterplane Area: 1 900 Square feet or 177 Square metres
    Displacement factor (Displacement / loading): 168%
    Structure weight / hull surface area: 61 lbs/sq ft or 298 Kg/sq metre
    Hull strength (Relative):
        - Cross-sectional: 2,45
        - Longitudinal: 1,48
        - Overall: 1,68
    Hull space for machinery, storage, compartmentation is cramped
    Room for accommodation and workspaces is extremely poor
    Ship has quick, lively roll, not a steady gun platform
    Caution: Lacks seaworthiness - very limited seakeeping ability

Operational depth:  168 ft / 51 m
Emergency Depth: 269 ft / 82 m
Crush depth: 420 ft / 128 m
