Nowa kanonierka torpedowa (1886)

Nowy typ kanonierki torpedowej - może niespecjalnie bardziej udany od poprzednika (patrz post z 10.01), ale na pewno zgrabniejszy:)

    3 - 18,0" / 457 mm above water torpedoes

Machinery:
    Coal fired boilers, complex reciprocating steam engines,
    Direct drive, 2 shafts, 3 995 ihp / 2 981 Kw = 19,50 kts
    Range 2 500nm at 10,00 kts
    Bunker at max displacement = 185 tons (100% coal)

Complement:
    74 - 97

Cost:
    £0,089 million / $0,355 million

Distribution of weights at normal displacement:
    Armament: 5 tons, 0,7%
    Machinery: 433 tons, 54,1%
    Hull, fittings & equipment: 234 tons, 29,3%
    Fuel, ammunition & stores: 124 tons, 15,5%
    Miscellaneous weights: 3 tons, 0,4%

Overall survivability and seakeeping ability:
    Survivability (Non-critical penetrating hits needed to sink ship):
      255 lbs / 116 Kg = 13,5 x 3,4 " / 87 mm shells or 0,2 torpedoes
    Stability (Unstable if below 1.00): 1,57
    Metacentric height 1,4 ft / 0,4 m
    Roll period: 9,1 seconds
    Steadiness    - As gun platform (Average = 50 %): 43 %
            - Recoil effect (Restricted arc if above 1.00): 0,03
    Seaboat quality  (Average = 1.00): 0,73

Hull form characteristics:
    Hull has rise forward of midbreak
    Block coefficient: 0,521
    Length to Beam Ratio: 8,05 : 1
    'Natural speed' for length: 14,42 kts
    Power going to wave formation at top speed: 60 %
    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):
       - Stem:        11,98 ft / 3,65 m
       - Forecastle (24%):    10,47 ft / 3,19 m
       - Mid (34%):        10,47 ft / 3,19 m (4,49 ft / 1,37 m aft of break)
       - Quarterdeck (18%):    5,48 ft / 1,67 m
       - Stern:        5,97 ft / 1,82 m
       - Average freeboard:    7,14 ft / 2,18 m
    Ship tends to be wet forward

Ship space, strength and comments:
    Space    - Hull below water (magazines/engines, low = better): 180,6%
        - Above water (accommodation/working, high = better): 39,8%
    Waterplane Area: 3 645 Square feet or 339 Square metres
    Displacement factor (Displacement / loading): 50%
    Structure weight / hull surface area: 41 lbs/sq ft or 198 Kg/sq metre
    Hull strength (Relative):
        - Cross-sectional: 0,96
        - Longitudinal: 1,46
        - Overall: 1,00
    Hull space for machinery, storage, compartmentation is cramped
    Room for accommodation and workspaces is extremely poor
    Poor seaboat, wet and uncomfortable, reduced performance in heavy weather
