Bavarian GTB

Bazhell - there's always a learning curve.  My first designs in springstyle were absolute disasters, and I've made quite a few mediocre ones since then.

He also developed a sense of understatement and modesty. ;)
Don't let Rock fool you, Bazhell... if you want to know what good designs look like, go check out Gran Colombia's newest ships.

I got it :)

   4 - 20,0" / 508 mm above water torpedoes

Machinery:
   Coal fired boilers, steam turbines,
   Direct drive, 2 shafts, 10.625 shp / 7.927 Kw = 27,00 kts
   Range 1.500nm at 12,50 kts

Complement:
   59 - 77

Cost:
   £0,067 million / $0,269 million

Distribution of weights at normal displacement:
   Armament: 8 tons, 1,3%
   Machinery: 309 tons, 52,7%
   Hull, fittings & equipment: 177 tons, 30,2%
   Fuel, ammunition & stores: 84 tons, 14,4%
   Miscellaneous weights: 8 tons, 1,4%

Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     146 lbs / 66 Kg = 7,0 x 3,5 " / 88 mm shells or 0,2 torpedoes
   Stability (Unstable if below 1.00): 1,08
   Metacentric height 0,5 ft / 0,2 m
   Roll period: 11,6 seconds
   Steadiness   - As gun platform (Average = 50 %): 96 %
         - Recoil effect (Restricted arc if above 1.00): 0,44
   Seaboat quality  (Average = 1.00): 1,59

Hull form characteristics:
   Hull has raised forecastle
   Block coefficient: 0,454
   Length to Beam Ratio: 11,83 : 1
   'Natural speed' for length: 15,26 kts
   Power going to wave formation at top speed: 66 %
   Trim (Max stability = 0, Max steadiness = 100): 60
   Bow angle (Positive = bow angles forward): 0,00 degrees
   Stern overhang: 0,00 ft / 0,00 m
   Freeboard (% = measuring location as a percentage of overall length):
      - Stem:      16,80 ft / 5,12 m
      - Forecastle (20%):   16,80 ft / 5,12 m (10,70 ft / 3,26 m aft of break)
      - Mid (50%):      10,70 ft / 3,26 m
      - Quarterdeck (15%):   10,70 ft / 3,26 m
      - Stern:      10,70 ft / 3,26 m
      - Average freeboard:   11,92 ft / 3,63 m

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 182,1%
      - Above water (accommodation/working, high = better): 46,1%
   Waterplane Area: 2.935 Square feet or 273 Square metres
   Displacement factor (Displacement / loading): 42%
   Structure weight / hull surface area: 21 lbs/sq ft or 102 Kg/sq metre
   Hull strength (Relative):
      - Cross-sectional: 0,50
      - Longitudinal: 4,57
      - Overall: 0,63
   Hull space for machinery, storage, compartmentation is cramped
   Room for accommodation and workspaces is extremely poor
   Ship has slow, easy roll, a good, steady gun platform
   Excellent seaboat, comfortable, can fire her guns in the heaviest weather

Ahoj!
OK.
You can trade - by changing trim - some "seaboat quality" for "stability".
