Distribution of weights at normal displacement:
   Armament: 11 tons, 1,9%
      - Guns: 8 tons, 1,5%
      - Weapons: 2 tons, 0,4%
   Machinery: 331 tons, 60,0%
   Hull, fittings & equipment: 105 tons, 19,0%
   Fuel, ammunition & stores: 102 tons, 18,5%
   Miscellaneous weights: 3 tons, 0,5%
      - On freeboard deck: 3 tons

Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     99 lbs / 45 Kg = 4,8 x 3,5 " / 88 mm shells or 0,4 torpedoes
   Stability (Unstable if below 1.00): 1,47
   Metacentric height 1,0 ft / 0,3 m
   Roll period: 9,2 seconds
   Steadiness   - As gun platform (Average = 50 %): 61 %
         - Recoil effect (Restricted arc if above 1.00): 0,09
   Seaboat quality  (Average = 1.00): 0,87

Hull form characteristics:
   Hull has raised forecastle,
     a normal bow and a round stern
   Block coefficient (normal/deep): 0,412 / 0,428
   Length to Beam Ratio: 9,85 : 1
   'Natural speed' for length: 14,72 kts
   Power going to wave formation at top speed: 65 %
   Trim (Max stability = 0, Max steadiness = 100): 70
   Bow angle (Positive = bow angles forward): 0,00 degrees
   Stern overhang: 3,28 ft / 1,00 m
   Freeboard (% = length of deck as a percentage of waterline length):
            Fore end,    Aft end
      - Forecastle:   20,00%,  13,12 ft / 4,00 m,  12,89 ft / 3,93 m
      - Forward deck:   30,00%,  7,22 ft / 2,20 m,  7,22 ft / 2,20 m
      - Aft deck:   35,00%,  7,22 ft / 2,20 m,  7,22 ft / 2,20 m
      - Quarter deck:   15,00%,  7,22 ft / 2,20 m,  7,22 ft / 2,20 m
      - Average freeboard:      8,37 ft / 2,55 m
   Ship tends to be wet forward

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 197,9%
      - Above water (accommodation/working, high = better): 63,4%
   Waterplane Area: 2.951 Square feet or 274 Square metres
   Displacement factor (Displacement Trial Speed: 28.56/ loading): 20%
   Structure weight / hull surface area: 20 lbs/sq ft or 95 Kg/sq metre
   Hull strength (Relative):
      - Cross-sectional: 0,50
      - Longitudinal: 1,34
      - Overall: 0,55
   Cramped machinery, storage, compartmentation space
   Cramped accommodation and workspace room
   Poor seaboat, wet and uncomfortable, reduced performance in heavy weather

Trial Speed: 28.56
