Pancernik Braunschweig - 8x280 - 21.03.2012

A oto niemiecka odpowiedź na Formidable'a - rozwinięci poprzedniego typu z tym, że z większym kalibrem dział - główne to 280-tki, a średnie - 170-tki w kazamatach. Na coś takiego Brytyjczycy będą musieli odpowiedzieć już chyba czymś naprawdę rewolucyjnym - i sporo potężniejszym od historycznego Dreadnoughta;-)

    Metacentric height 4,4 ft / 1,4 m
    Roll period: 15,9 seconds
    Steadiness    - As gun platform (Average = 50 %): 70 %
            - Recoil effect (Restricted arc if above 1.00): 0,65
    Seaboat quality  (Average = 1.00): 1,41

Hull form characteristics:
    Hull has a flush deck
    Block coefficient: 0,584
    Length to Beam Ratio: 6,30 : 1
    'Natural speed' for length: 22,41 kts
    Power going to wave formation at top speed: 42 %
    Trim (Max stability = 0, Max steadiness = 100): 50
    Bow angle (Positive = bow angles forward): -14,00 degrees
    Stern overhang: 0,00 ft / 0,00 m
    Freeboard (% = measuring location as a percentage of overall length):

       - Average freeboard:    17,22 ft / 5,25 m
    Ship tends to be wet forward

Ship space, strength and comments:
    Space    - Hull below water (magazines/engines, low = better): 132,5%
        - Above water (accommodation/working, high = better): 124,8%
    Waterplane Area: 28 881 Square feet or 2 683 Square metres
    Displacement factor (Displacement / loading): 94%
    Structure weight / hull surface area: 150 lbs/sq ft or 732 Kg/sq metre
    Hull strength (Relative):
        - Cross-sectional: 0,95

        - Overall: 1,00
    Hull space for machinery, storage, compartmentation is cramped
    Room for accommodation and workspaces is excellent
    Ship has slow, easy roll, a good, steady gun platform
    Good seaboat, rides out heavy weather easily
