Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     4.080 lbs / 1.851 Kg = 280,3 x 3,5 " / 88 mm shells or 1,4 torpedoes
   Stability (Unstable if below 1.00): 1,10
   Metacentric height 1,1 ft / 0,3 m
   Roll period: 13,0 seconds
   Steadiness   - As gun platform (Average = 50 %): 30 %
         - Recoil effect (Restricted arc if above 1.00): 0,05
   Seaboat quality  (Average = 1.00): 1,20

Hull form characteristics:
   Hull has a flush deck
   Block coefficient: 0,446
   Length to Beam Ratio: 8,00 : 1
