Distribution of weights at normal displacement:
   Armament: 4 tons, 0,6 %
   Armour: 1 tons, 0,2 %
      - Belts: 0 tons, 0,0 %
      - Torpedo bulkhead: 0 tons, 0,0 %
      - Armament: 0 tons, 0,0 %
      - Armour Deck: 0 tons, 0,0 %
      - Conning Tower: 1 tons, 0,2 %
   Machinery: 57 tons, 9,2 %
   Hull, fittings & equipment: 337 tons, 54,4 %
   Fuel, ammunition & stores: 121 tons, 19,5 %
   Miscellaneous weights: 100 tons, 16,1 %

Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     472 lbs / 214 Kg = 15,5 x 3,9 " / 100 mm shells or 0,6 torpedoes
   Stability (Unstable if below 1.00): 1,19
   Metacentric height 0,7 ft / 0,2 m
   Roll period: 10,9 seconds
   Steadiness   - As gun platform (Average = 50 %): 0 %
         - Recoil effect (Restricted arc if above 1.00): 0,00
   Seaboat quality  (Average = 1.00): 0,00

Hull form characteristics:
   Hull has a flush deck
   Block coefficient: 0,394
   Length to Beam Ratio: 9,23 : 1
   'Natural speed' for length: 14,03 kts
   Power going to wave formation at top speed: 43 %
   Trim (Max stability = 0, Max steadiness = 100): 49
   Bow angle (Positive = bow angles forward): 7,00 degrees
   Stern overhang: 0,00 ft / 0,00 m
   Freeboard (% = measuring location as a percentage of overall length):
      - Stem:      0,00 ft / 0,00 m
      - Forecastle (20 %):   0,00 ft / 0,00 m
      - Mid (50 %):      0,00 ft / 0,00 m
      - Quarterdeck (15 %):   0,00 ft / 0,00 m
      - Stern:      0,00 ft / 0,00 m
      - Average freeboard:   0,00 ft / 0,00 m
   Ship tends to be wet forward

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 71,5 %
      - Above water (accommodation/working, high = better): 0,0 %
   Waterplane Area: 2.576 Square feet or 239 Square metres
   Displacement factor (Displacement / loading): 253 %
   Structure weight / hull surface area: 88 lbs/sq ft or 428 Kg/sq metre
   Hull strength (Relative):
      - Cross-sectional: 3,00
      - Longitudinal: 2,06
      - Overall: 2,26
   Hull space for machinery, storage, compartmentation is excellent
   Room for accommodation and workspaces is extremely poor
   Ship has quick, lively roll, not a steady gun platform
   Caution: Lacks seaworthiness - very limited seakeeping ability
