Overall survivability and seakeeping ability:
  Survivability (Non-critical penetrating hits needed to sink ship):
    109 lbs / 49 Kg = 3.4 x 4.0 " / 102 mm shells or 0.2 torpedoes
  Stability (Unstable if below 1.00): 1.43
  Metacentric height 1.0 ft / 0.3 m
  Roll period: 9.4 seconds
  Steadiness   - As gun platform (Average = 50 %): 70 %
        - Recoil effect (Restricted arc if above 1.00): 0.22
  Seaboat quality  (Average = 1.00): 1.28

Hull form characteristics:
  Hull has a flush deck
  Block coefficient: 0.497
  Length to Beam Ratio: 9.55 : 1
  'Natural speed' for length: 14.49 kts
  Power going to wave formation at top speed: 57 %
  Trim (Max stability = 0, Max steadiness = 100): 55
  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:      14.00 ft / 4.27 m
     - Forecastle (20 %):   9.00 ft / 2.74 m
     - Mid (50 %):      9.00 ft / 2.74 m
     - Quarterdeck (15 %):   8.00 ft / 2.44 m
     - Stern:      8.00 ft / 2.44 m
     - Average freeboard:   9.08 ft / 2.77 m
  Ship tends to be wet forward

Ship space, strength and comments:
  Space   - Hull below water (magazines/engines, low = better): 176.8 %
     - Above water (accommodation/working, high = better): 153.3 %
  Waterplane Area: 2,949 Square feet or 274 Square metres
  Displacement factor (Displacement / loading): 53 %
  Structure weight / hull surface area: 19 lbs/sq ft or 93 Kg/sq metre
  Hull strength (Relative):
     - Cross-sectional: 0.51
     - Longitudinal: 1.52
     - Overall: 0.57
  Caution: Hull subject to strain in open-sea
  Hull space for machinery, storage, compartmentation is cramped
  Room for accommodation and workspaces is excellent
  Ship has slow, easy roll, a good, steady gun platform
  Good seaboat, rides out heavy weather easily
