Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     25.743 lbs / 11.677 Kg = 432,0 x 4,9 " / 125 mm shells or 5,5 torpedoes
   Stability (Unstable if below 1.00): 1,63
   Metacentric height 3,5 ft / 1,1 m
   Roll period: 10,3 seconds
   Steadiness   - As gun platform (Average = 50 %): 89 %
         - Recoil effect (Restricted arc if above 1.00): 0,02
   Seaboat quality  (Average = 1.00): 1,77

Hull form characteristics:
   Hull has a flush deck
   Block coefficient: 0,648
   Length to Beam Ratio: 8,43 : 1
   'Natural speed' for length: 19,68 kts
   Power going to wave formation at top speed: 44 %
   Trim (Max stability = 0, Max steadiness = 100): 50
