Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     51.651 lbs / 23.429 Kg = 30,9 x 15,0 " / 380 mm shells or 8,5 torpedoes
   Stability (Unstable if below 1.00): 1,17
   Metacentric height 7,6 ft / 2,3 m
   Roll period: 16,5 seconds
   Steadiness   - As gun platform (Average = 50 %): 65 %
         - Recoil effect (Restricted arc if above 1.00): 0,53
   Seaboat quality  (Average = 1.00): 1,30

Hull form characteristics:
   Hull has a flush deck
   Block coefficient: 0,556
   Length to Beam Ratio: 6,61 : 1
   'Natural speed' for length: 26,74 kts
   Power going to wave formation at top speed: 47 %
   Trim (Max stability = 0, Max steadiness = 100): 50

   Hull space for machinery, storage, compartmentation is adequate
   Room for accommodation and workspaces is excellent
   Good seaboat, rides out heavy weather easily

The Rock Doctor

Why single deck mounts versus casemates?  The latter would be better protected.

Casemate gun is a problem in medium/high seaways,and these ships is operate in the Atlantic
