    6 - 0,0" / 0 mm above water torpedoes, 533 - 0,0" / 0 mm submerged torpedo tubes

Machinery:
    Oil fired boilers, steam turbines,
    Geared drive, 1 shaft, 18 957 shp / 14 142 Kw = 33,00 kts
    Range 1 200nm at 14,00 kts
    Bunker at max displacement = 34 tons
      Caution: Delicate, lightweight machinery

Complement:
    38 - 50

Cost:
    £0,167 million / $0,667 million

Distribution of weights at normal displacement:
    Armament: 3 tons, 1,0%
    Machinery: 188 tons, 56,7%
    Hull, fittings & equipment: 112 tons, 33,7%
    Fuel, ammunition & stores: 28 tons, 8,6%
    Miscellaneous weights: 0 tons, 0,0%

Overall survivability and seakeeping ability:
    Survivability (Non-critical penetrating hits needed to sink ship):
      79 lbs / 36 Kg = 5,9 x 3,0 " / 76 mm shells or 0,1 torpedoes
    Stability (Unstable if below 1.00): 1,38
    Metacentric height 0,7 ft / 0,2 m
    Roll period: 9,3 seconds
    Steadiness    - As gun platform (Average = 50 %): 31 %
            - Recoil effect (Restricted arc if above 1.00): 0,11
    Seaboat quality  (Average = 1.00): 0,38

Hull form characteristics:
    Hull has a flush deck
    Block coefficient: 0,426
    Length to Beam Ratio: 10,93 : 1
    'Natural speed' for length: 14,42 kts
    Power going to wave formation at top speed: 77 %
    Trim (Max stability = 0, Max steadiness = 100): 50
    Bow angle (Positive = bow angles forward): 25,00 degrees
    Stern overhang: 0,00 ft / 0,00 m
    Freeboard (% = measuring location as a percentage of overall length):
       - Stem:        13,45 ft / 4,10 m
       - Forecastle (20%):    9,51 ft / 2,90 m
       - Mid (50%):        9,51 ft / 2,90 m
       - Quarterdeck (15%):    9,51 ft / 2,90 m
       - Stern:        9,84 ft / 3,00 m
       - Average freeboard:    9,85 ft / 3,00 m
    Ship tends to be wet forward

Ship space, strength and comments:
    Space    - Hull below water (magazines/engines, low = better): 191,2%
        - Above water (accommodation/working, high = better): 112,2%
    Waterplane Area: 2 352 Square feet or 219 Square metres
    Displacement factor (Displacement / loading): 29%
    Structure weight / hull surface area: 19 lbs/sq ft or 95 Kg/sq metre
    Hull strength (Relative):
        - Cross-sectional: 0,41
        - Longitudinal: 3,26
        - Overall: 0,50
    Hull space for machinery, storage, compartmentation is cramped
    Room for accommodation and workspaces is adequate
    Caution: Lacks seaworthiness - very limited seakeeping ability
