Kanonierki rzeczne na Jangcy

Tym razem coś opancerzonego :) W uzupełnieniu do gromadki rzecznych drobnoustrojów z postu z 24 kwietnia, prezentuję dwie nowe kanonierki rzeczne przeznaczone na Jangcy. Jest to ostatni chyba przed wojną etap programu rozbudowy sił rzecznych w koloniach, które osiągnęły tym samym swój docelowy kształt. Być może przed wojna pojawią się jeszcze jakieś okręty rzeczne przeznaczone dla flotylli w kraju. Flotylle z posiadłościach zamorskich natomiast są już chyba wystarczająco silne.

Overall survivability and seakeeping ability:
    Survivability (Non-critical penetrating hits needed to sink ship):
      435 lbs / 197 Kg = 8,3 x 4,7 " / 120 mm shells or 0,4 torpedoes
    Stability (Unstable if below 1.00): 1,67
    Metacentric height 1,5 ft / 0,5 m
    Roll period: 8,7 seconds
    Steadiness    - As gun platform (Average = 50 %): 42 %
            - Recoil effect (Restricted arc if above 1.00): 0,11
    Seaboat quality  (Average = 1.00): 0,70

Hull form characteristics:
    Hull has a flush deck
    Block coefficient: 0,590
    Length to Beam Ratio: 7,28 : 1
    'Natural speed' for length: 13,69 kts
    Power going to wave formation at top speed: 41 %
    Trim (Max stability = 0, Max steadiness = 100): 50
    Bow angle (Positive = bow angles forward): 0,00 degrees
    Stern overhang: 0,49 ft / 0,15 m

        - Above water (accommodation/working, high = better): 93,4%
    Waterplane Area: 3 414 Square feet or 317 Square metres
    Displacement factor (Displacement / loading): 106%
    Structure weight / hull surface area: 37 lbs/sq ft or 180 Kg/sq metre
