   Roll period: 13.9 seconds
   Steadiness   - As gun platform (Average = 50 %): 68 %
         - Recoil effect (Restricted arc if above 1.00): 0.62
   Seaboat quality  (Average = 1.00): 1.35

Hull form characteristics:
   Hull has a flush deck,
     a ram bow and a cruiser stern
   Block coefficient (normal/deep): 0.680 / 0.685
   Length to Beam Ratio: 6.67 : 1
   'Natural speed' for length: 19.84 kts
   Power going to wave formation at top speed: 47 %
   Trim (Max stability = 0, Max steadiness = 100): 50
   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 %,  14.76 ft / 4.50 m,  13.12 ft / 4.00 m

      - Average freeboard:      13.25 ft / 4.04 m
   Ship tends to be wet forward

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 92.5 %
      - Above water (accommodation/working, high = better): 98.8 %
