      - Stern:      13,12 ft / 4,00 m
      - Average freeboard:   16,17 ft / 4,93 m
   Ship tends to be wet forward

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 103,5 %
      - Above water (accommodation/working, high = better): 122,3 %
   Waterplane Area: 16.480 Square feet or 1.531 Square metres
   Displacement factor (Displacement / loading): 108 %
   Structure weight / hull surface area: 85 lbs/sq ft or 413 Kg/sq metre
   Hull strength (Relative):
      - Cross-sectional: 0,96

      - Overall: 1,00
   Hull space for machinery, storage, compartmentation is adequate
   Room for accommodation and workspaces is excellent

Armor is on the thick side and belt is not deep enough imho. 6" can withstand 8-9" shells from the distance, but the ship won't damage ships with such armament. I don't think you need upper belt, either.
