   Fuel, ammunition & stores: 174 tons, 14.8 %
   Miscellaneous weights: 66 tons, 5.6 %

Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     260 lbs / 118 Kg = 4.9 x 4.7 " / 120 mm shells or 0.2 torpedoes
   Stability (Unstable if below 1.00): 1.39
   Metacentric height 1.2 ft / 0.4 m
   Roll period: 10.1 seconds
   Steadiness   - As gun platform (Average = 50 %): 51 %
         - Recoil effect (Restricted arc if above 1.00): 0.33
   Seaboat quality  (Average = 1.00): 1.01

Hull form characteristics:
   Hull has raised forecastle
   Block coefficient: 0.423
   Length to Beam Ratio: 11.04 : 1
   'Natural speed' for length: 17.18 kts
   Power going to wave formation at top speed: 67 %
   Trim (Max stability = 0, Max steadiness = 100): 50
   Bow angle (Positive = bow angles forward): 22.00 degrees
   Stern overhang: 0.00 ft / 0.00 m
   Freeboard (% = measuring location as a percentage of overall length):
      - Stem:      18.90 ft / 5.76 m
      - Forecastle (20 %):   14.44 ft / 4.40 m (11.15 ft / 3.40 m aft of break)
      - Mid (50 %):      11.15 ft / 3.40 m
      - Quarterdeck (15 %):   11.15 ft / 3.40 m
      - Stern:      11.15 ft / 3.40 m
      - Average freeboard:   12.17 ft / 3.71 m
   Ship tends to be wet forward

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 189.3 %
      - Above water (accommodation/working, high = better): 105.9 %
   Waterplane Area: 4,933 Square feet or 458 Square metres
   Displacement factor (Displacement / loading): 51 %
   Structure weight / hull surface area: 28 lbs/sq ft or 136 Kg/sq metre
   Hull strength (Relative):
      - Cross-sectional: 0.50
      - Longitudinal: 2.06
      - Overall: 0.58
   Hull space for machinery, storage, compartmentation is cramped
   Room for accommodation and workspaces is adequate
