      - Above water (accommodation/working, high = better): 126,2 %
   Waterplane Area: 4.315 Square feet or 401 Square metres
   Displacement factor (Displacement / loading): 150 %
   Structure weight / hull surface area: 43 lbs/sq ft or 212 Kg/sq metre
   Hull strength (Relative):
      - Cross-sectional: 0,88
      - Longitudinal: 2,95
      - Overall: 1,00
   Hull space for machinery, storage, compartmentation is excellent
   Room for accommodation and workspaces is excellent
   Ship has slow, easy roll, a good, steady gun platform

100 mm end =protection

The 100 mm end armor is for Ice-breaking and protection in the Greenland area.
Intention is to build 3 to 5 vessels in the coming years under mercantile rules

[maddox]

I'm afraid it won't work.  Mercantile rules state that armament and armor cannot exceed 2%.
