Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     7 875 lbs / 3 572 Kg = 72,9 x 6,0 " / 152 mm shells or 1,3 torpedoes
   Stability (Unstable if below 1.00): 1,35
   Metacentric height 3,4 ft / 1,0 m
   Roll period: 12,4 seconds
   Steadiness   - As gun platform (Average = 50 %): 75 %
         - Recoil effect (Restricted arc if above 1.00): 0,23
   Seaboat quality  (Average = 1.00): 1,50

Hull form characteristics:
   Hull has rise forward of midbreak
   Block coefficient: 0,598
   Length to Beam Ratio: 7,04 : 1
   'Natural speed' for length: 19,49 kts
   Power going to wave formation at top speed: 57 %
   Trim (Max stability = 0, Max steadiness = 100): 50
   Bow angle (Positive = bow angles forward): 0,00 degrees

So I guess we're going to have a collective Antarctic land grab then? The penguins will be miffed.

The Colombians might get pissy if somebody seeks to stick military facilities down there, but otherwise, I think they'd rather grab tropical lands.
