Nowa kanonierka

Nowy typ kanonierki jest w zamierzeniu okrętem uniwersalnym, przydatnym zarówno w koloniach, jak i na wodach macierzystych. Nie stanowi co prawda żadnego przełomu w stosunku do poprzedniego typu, ale uznałem, że tamtego mamy za mało (raptem 4 jednostki) i konieczne jest uzupełnienie:)

Pegaz, polish gunboat laid down 1876

Displacement:
    714 t light; 746 t standard; 913 t normal; 1 046 t full load

Dimensions: Length overall / water x beam x draught
    185,99 ft / 177,00 ft x 30,15 ft x 11,88 ft (normal load)
    56,69 m / 53,95 m x 9,19 m  x 3,62 m

Armament:
      2 - 5,98" / 152 mm guns in single mounts, 84,65lbs / 38,40kg shells, 1876 Model
      Breech loading guns in deck mounts
      on centreline, all amidships
    Weight of broadside 169 lbs / 77 kg
    Shells per gun, main battery: 150

Machinery:
    Coal fired boilers, simple reciprocating steam engines,
    Direct drive, 1 shaft, 1 036 ihp / 773 Kw = 13,00 kts
    Range 4 000nm at 8,50 kts
    Bunker at max displacement = 300 tons (100% coal)

Complement:
    157

Cost:
    £0,075 million / $0,298 million

Distribution of weights at normal displacement:
    Armament: 21 tons, 2,3%
    Machinery: 227 tons, 24,9%
    Hull, fittings & equipment: 388 tons, 42,5%
    Fuel, ammunition & stores: 199 tons, 21,8%
    Miscellaneous weights: 77 tons, 8,4%

Overall survivability and seakeeping ability:
    Survivability (Non-critical penetrating hits needed to sink ship):
      768 lbs / 348 Kg = 9,1 x 6,0 " / 152 mm shells or 0,4 torpedoes
    Stability (Unstable if below 1.00): 1,17
    Metacentric height 1,1 ft / 0,3 m
    Roll period: 11,9 seconds
    Steadiness    - As gun platform (Average = 50 %): 100 %
            - Recoil effect (Restricted arc if above 1.00): 0,31
    Seaboat quality  (Average = 1.00): 2,00

Hull form characteristics:
    Hull has a flush deck
    Block coefficient: 0,508
    Length to Beam Ratio: 5,92 : 1
    'Natural speed' for length: 13,30 kts
    Power going to wave formation at top speed: 47 %
    Trim (Max stability = 0, Max steadiness = 100): 50
    Bow angle (Positive = bow angles forward): -2,00 degrees
    Stern overhang: 8,99 ft / 2,74 m
    Freeboard (% = measuring location as a percentage of overall length):
       - Stem:        13,45 ft / 4,10 m
       - Forecastle (18%):    12,50 ft / 3,81 m
       - Mid (50%):        11,45 ft / 3,49 m
       - Quarterdeck (16%):    12,50 ft / 3,81 m
       - Stern:        13,98 ft / 4,26 m
       - Average freeboard:    12,34 ft / 3,76 m
    Ship tends to be wet forward

Ship space, strength and comments:
    Space    - Hull below water (magazines/engines, low = better): 108,0%
        - Above water (accommodation/working, high = better): 95,9%
    Waterplane Area: 3 448 Square feet or 320 Square metres
    Displacement factor (Displacement / loading): 130%
    Structure weight / hull surface area: 58 lbs/sq ft or 282 Kg/sq metre
    Hull strength (Relative):
        - Cross-sectional: 0,89
        - Longitudinal: 6,28
        - Overall: 1,08
    Hull space for machinery, storage, compartmentation is adequate
    Room for accommodation and workspaces is adequate
    Ship has slow, easy roll, a good, steady gun platform
    Excellent seaboat, comfortable, can fire her guns in the heaviest weather

  1. Nowa? Wygląda jakby była stara. Bardzo stara. W porównaniu z tym pancernikiem wieżowym to gdzieś tak pierwsza połowa XVIII wieku :-).
