   Fuel, ammunition & stores: 124 tons, 6.8 %
   Miscellaneous weights: 500 tons, 27.4 %

Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
    4,839 lbs / 2,195 Kg = 137.0 x 4.1 " / 105 mm shells or 2.3 torpedoes
   Stability (Unstable if below 1.00): 1.13
   Metacentric height 1.8 ft / 0.5 m
   Roll period: 13.5 seconds
   Steadiness   - As gun platform (Average = 50 %): 51 %
         - Recoil effect (Restricted arc if above 1.00): 0.03
   Seaboat quality (Average = 1.00): 1.95

Hull form characteristics:
   Hull has a flush deck
   Block coefficient: 0.451
   Length to Beam Ratio: 5.38 : 1
   'Natural speed' for length: 15.15 kts
   Power going to wave formation at top speed: 25 %
   Trim (Max stability = 0, Max steadiness = 100): 26
   Bow angle (Positive = bow angles forward): 59.00 degrees
   Stern overhang: 0.00 ft / 0.00 m
   Freeboard (% = measuring location as a percentage of overall length):
    - Stem:      16.67 ft / 5.08 m
    - Forecastle (20 %):   10.60 ft / 3.23 m
    - Mid (50 %):      10.60 ft / 3.23 m
    - Quarterdeck (15 %):   10.60 ft / 3.23 m
    - Stern:      10.60 ft / 3.23 m
    - Average freeboard:   11.08 ft / 3.38 m
   Ship tends to be wet forward

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 39.8 %
      - Above water (accommodation/working, high = better): 86.5 %
   Waterplane Area: 5,959 Square feet or 554 Square metres
   Displacement factor (Displacement / loading): 290 %
   Structure weight / hull surface area: 124 lbs/sq ft or 603 Kg/sq metre
   Hull strength (Relative):
      - Cross-sectional: 2.21
      - Longitudinal: 6.71
      - Overall: 2.47
   Hull space for machinery, storage, compartmentation is excellent
   Room for accommodation and workspaces is cramped
   Excellent seaboat, comfortable, can fire her guns in the heaviest weather

A Sail Training ship for the nascent Bavarian Navy.

She is equipped with an auxiliary engine capable of driving her at 9.5kts and sufficient range to tour the med.
