Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     45.648 lbs / 20.706 Kg = 27,3 x 15,0 " / 380 mm shells or 6,7 torpedoes
   Stability (Unstable if below 1.00): 1,18
   Metacentric height 7,6 ft / 2,3 m
   Roll period: 16,5 seconds
   Steadiness   - As gun platform (Average = 50 %): 51 %
         - Recoil effect (Restricted arc if above 1.00): 0,41
   Seaboat quality  (Average = 1.00): 1,02

Hull form characteristics:
   Hull has a flush deck
   Block coefficient: 0,540
   Length to Beam Ratio: 6,63 : 1
   'Natural speed' for length: 26,79 kts
   Power going to wave formation at top speed: 50 %
   Trim (Max stability = 0, Max steadiness = 100): 50
   Bow angle (Positive = bow angles forward): 10,00 degrees
   Stern overhang: 0,00 ft / 0,00 m
