Machinery:
  Coal and oil fired boilers, steam turbines,
  Direct drive, 2 shafts, 3 226 shp / 2 406 Kw = 24,85 kts
  Range 150nm at 24,85 kts
  Bunker at max displacement = 29 tons (90% coal)

Complement:

Cost:
  £0,013 million / $0,054 million

Distribution of weights at normal displacement:
  Armament: 1 tons, 0,7 %
  Machinery: 66 tons, 55,0 %
  Hull, fittings & equipment: 32 tons, 26,8 %
  Fuel, ammunition & stores: 19 tons, 15,8 %
  Miscellaneous weights: 2 tons, 1,7 %

Overall survivability and seakeeping ability:
  Survivability (Non-critical penetrating hits needed to sink ship):
    27 lbs / 12 Kg = 4,1 x 2,4 " / 60 mm shells or 0,1 torpedoes
  Stability (Unstable if below 1.00): 1,18
  Metacentric height 0,3 ft / 0,1 m
  Roll period: 9,7 seconds
  Steadiness   - As gun platform (Average = 50 %): 49 %
        - Recoil effect (Restricted arc if above 1.00): 0,08
  Seaboat quality  (Average = 1.00): 0,70

Hull form characteristics:
  Hull has a flush deck
  Block coefficient: 0,385
  Length to Beam Ratio: 12,00 : 1
  'Natural speed' for length: 12,55 kts
  Power going to wave formation at top speed: 67 %
  Trim (Max stability = 0, Max steadiness = 100): 70
  Bow angle (Positive = bow angles forward): 0,00 degrees
  Stern overhang: 0,00 ft / 0,00 m
  Freeboard (% = measuring location as a percentage of overall length):
     - Stem:      8,20 ft / 2,50 m
     - Forecastle (10 %):   7,94 ft / 2,42 m
     - Mid (30 %):      4,92 ft / 1,50 m
     - Quarterdeck (15 %):   4,92 ft / 1,50 m
     - Stern:      4,92 ft / 1,50 m
     - Average freeboard:   5,54 ft / 1,69 m
  Ship tends to be wet forward

Ship space, strength and comments:
  Space   - Hull below water (magazines/engines, low = better): 184,4 %
     - Above water (accommodation/working, high = better): 39,6 %
  Waterplane Area: 1 263 Square feet or 117 Square metres
  Displacement factor (Displacement / loading): 36 %
  Structure weight / hull surface area: 13 lbs/sq ft or 62 Kg/sq metre
  Hull strength (Relative):
     - Cross-sectional: 0,50
     - Longitudinal: 1,37
     - Overall: 0,55
  Hull space for machinery, storage, compartmentation is cramped
  Room for accommodation and workspaces is extremely poor
  Caution: Lacks seaworthiness - very limited seakeeping ability
