Distribution of weights at normal displacement:
   Armament: 8 tons, 1.5 %
   Armour: 3 tons, 0.6 %
      - Belts: 0 tons, 0.0 %
      - Torpedo bulkhead: 0 tons, 0.0 %
      - Armament: 2 tons, 0.4 %
      - Armour Deck: 0 tons, 0.0 %
      - Conning Tower: 1 tons, 0.1 %
   Machinery: 281 tons, 50.8 %
   Hull, fittings & equipment: 193 tons, 34.9 %
   Fuel, ammunition & stores: 54 tons, 9.7 %
   Miscellaneous weights: 14 tons, 2.5 %

Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     166 lbs / 75 Kg = 5.2 x 4.0 " / 102 mm shells or 0.2 torpedoes
   Stability (Unstable if below 1.00): 1.08
   Metacentric height 0.5 ft / 0.2 m
   Roll period: 11.7 seconds
   Steadiness   - As gun platform (Average = 50 %): 70 %
         - Recoil effect (Restricted arc if above 1.00): 0.39
   Seaboat quality  (Average = 1.00): 1.43

Hull form characteristics:
   Hull has a flush deck
   Block coefficient: 0.490
   Length to Beam Ratio: 11.00 : 1
   'Natural speed' for length: 14.83 kts
   Power going to wave formation at top speed: 70 %
   Trim (Max stability = 0, Max steadiness = 100): 49
   Bow angle (Positive = bow angles forward): 16.40 degrees
   Stern overhang: 5.00 ft / 1.52 m
   Freeboard (% = measuring location as a percentage of overall length):
      - Stem:      17.00 ft / 5.18 m
      - Forecastle (20 %):   14.00 ft / 4.27 m
      - Mid (50 %):      12.00 ft / 3.66 m
      - Quarterdeck (15 %):   12.00 ft / 3.66 m
      - Stern:      12.00 ft / 3.66 m
      - Average freeboard:   12.94 ft / 3.94 m

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 178.4 %
      - Above water (accommodation/working, high = better): 51.0 %
   Waterplane Area: 2,787 Square feet or 259 Square metres
   Displacement factor (Displacement / loading): 47 %
   Structure weight / hull surface area: 22 lbs/sq ft or 109 Kg/sq metre
   Hull strength (Relative):
      - Cross-sectional: 0.51
      - Longitudinal: 7.06
      - Overall: 0.66
   Hull space for machinery, storage, compartmentation is cramped
   Room for accommodation and workspaces is cramped
   Ship has slow, easy roll, a good, steady gun platform
   Good seaboat, rides out heavy weather easily
