   Metacentric height 7,7 ft / 2,4 m
   Roll period: 11,9 seconds
   Steadiness   - As gun platform (Average = 50 %): 100 %
         - Recoil effect (Restricted arc if above 1.00): 0,00
   Seaboat quality  (Average = 1.00): 1,92

Hull form characteristics:
   Hull has a flush deck
   Block coefficient: 0,487
   Length to Beam Ratio: 4,95 : 1
   'Natural speed' for length: 19,73 kts
   Power going to wave formation at top speed: 46 %
   Trim (Max stability = 0, Max steadiness = 100): 53
