Cost:
   £0.006 million / $0.022 million

Distribution of weights at normal displacement:
   Armament: 1 tons, 1.3%
      - Guns: 1 tons, 1.3%
   Machinery: 27 tons, 53.7%
   Hull, fittings & equipment: 10 tons, 19.2%

   Miscellaneous weights: 8 tons, 15.9%
      - On freeboard deck: 8 tons

Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     11 lbs / 5 Kg = 3.9 x 1.8 " / 45 mm shells or 0.1 torpedoes
   Stability (Unstable if below 1.00): 1.13
   Metacentric height 0.2 ft / 0.1 m
   Roll period: 9.8 seconds
   Steadiness   - As gun platform (Average = 50 %): 51 %
         - Recoil effect (Restricted arc if above 1.00): 0.05
   Seaboat quality  (Average = 1.00): 0.72

Hull form characteristics:
   Hull has a flush deck,
     a normal bow and a cruiser stern
   Block coefficient (normal/deep): 0.380 / 0.388
   Length to Beam Ratio: 9.71 : 1
   'Natural speed' for length: 10.56 kts
   Power going to wave formation at top speed: 59 %
   Trim (Max stability = 0, Max steadiness = 100): 71
   Bow angle (Positive = bow angles forward): 0.00 degrees
   Stern overhang: 0.00 ft / 0.00 m
   Freeboard (% = length of deck as a percentage of waterline length):
            Fore end,    Aft end
      - Forecastle:   20.00%,  3.28 ft / 1.00 m,  3.28 ft / 1.00 m
      - Forward deck:   30.00%,  3.28 ft / 1.00 m,  3.28 ft / 1.00 m
      - Aft deck:   35.00%,  3.28 ft / 1.00 m,  3.28 ft / 1.00 m
      - Quarter deck:   15.00%,  3.28 ft / 1.00 m,  3.28 ft / 1.00 m
      - Average freeboard:      3.28 ft / 1.00 m
   Ship tends to be wet forward

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 177.0%
      - Above water (accommodation/working, high = better): 54.0%
   Waterplane Area: 778 Square feet or 72 Square metres
   Displacement factor (Displacement / loading): 32%
   Structure weight / hull surface area: 8 lbs/sq ft or 41 Kg/sq metre
   Hull strength (Relative):
      - Cross-sectional: 0.50
      - Longitudinal: 0.64
      - Overall: 0.52
   Caution: Hull subject to strain in open-sea
   Cramped machinery, storage, compartmentation space
   Cramped accommodation and workspace room
   Poor seaboat, wet and uncomfortable, reduced performance in heavy weather

Trial Speed 27 knots

I don't get it... I calculated, calculated and recalculated things while working on the sims with all the changes going on with the monitor as the final ship that would increase slightly to take up any remaining tons that I had left in the end...

... and now that it is all done, I suddenly find that I am 40 tons over the limit that I have sent for the fleet...  ???

Walter

Corrected the 200mm guns and shaved a few tons from the monitor design to get to what I wanted.

Current plan looks like this with 15 BP set aside for naval infrastructure and the remaining 105 BP used for the fleet...

How is it that you have so many ships with only 105 BP? I have more and only get...O, wait, the 18t boats...*shows self out*
You smug-faced crowds with kindling eye
Who cheer when solider lads march by
Sneak home and pray that you'll never know
The hell where youth and laughter go.
-Siegfried Sassoon

A fleet is always going to hae a large number of ships when the ships are tiny. Wesworld Japan has a massive submarine fleet of 315... until you realize that about 40% are midget submarines. If you look at the R-17 RGB, you can have 1166 of them with 105 BPs. There will be more than 5800 of those tiny 18t patrol boats if all the 105 BPs were spent on only them.
