Something for the Danube?

[Borys]

The six incher would be a L30 howitzer, the 3,5" a L40 howitzer.
The one-pounders are pom-poms.

Distribution of weights at normal displacement:
   Armament: 17 tons, 7,5%

   Miscellaneous weights: 15 tons, 6,7%

Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     228 lbs / 103 Kg = 2,1 x 6,0 " / 152 mm shells or 0,3 torpedoes
   Stability (Unstable if below 1.00): 1,10
   Metacentric height 0,5 ft / 0,2 m
   Roll period: 11,5 seconds
   Steadiness   - As gun platform (Average = 50 %): 42 %
         - Recoil effect (Restricted arc if above 1.00): 0,43
   Seaboat quality  (Average = 1.00): 0,58

Hull form characteristics:
   Hull has a flush deck
   Block coefficient: 0,697
   Length to Beam Ratio: 4,00 : 1
   'Natural speed' for length: 8,94 kts
   Power going to wave formation at top speed: 72 %
   Trim (Max stability = 0, Max steadiness = 100): 60
   Bow angle (Positive = bow angles forward): 0,00 degrees
   Stern overhang: 6,00 ft / 1,83 m
   Freeboard (% = measuring location as a percentage of overall length):
      - Stem:      7,00 ft / 2,13 m
      - Forecastle (20%):   6,00 ft / 1,83 m
      - Mid (50%):      6,00 ft / 1,83 m
      - Quarterdeck (15%):   6,00 ft / 1,83 m
      - Stern:      6,00 ft / 1,83 m
      - Average freeboard:   6,08 ft / 1,85 m
   Ship tends to be wet forward

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 100,8%
      - Above water (accommodation/working, high = better): 52,2%
   Waterplane Area: 1 279 Square feet or 119 Square metres
   Displacement factor (Displacement / loading): 79%
   Structure weight / hull surface area: 36 lbs/sq ft or 176 Kg/sq metre
   Hull strength (Relative):
      - Cross-sectional: 1,00
      - Longitudinal: 7,08
      - Overall: 1,21
   Hull space for machinery, storage, compartmentation is adequate
   Room for accommodation and workspaces is cramped
   Caution: Lacks seaworthiness - very limited seakeeping ability

Warning: Calibre too large for machine gun - 3rd battery

I suspect that would be rather handy.
