Well, Sunday was a day when one was to tired to do anything serious. So I started thinking about what kind of ships Bavaria would build (ok, I really just wanted a reason to draw something a bit different). And here is the result:

Maximillian, Bavaria Schnellkreuzer laid down 1912

Displacement:
   6 220 t light; 6 425 t standard; 7 001 t normal; 7 462 t full load

Machinery:
   Oil fired boilers, steam turbines,
   Direct drive, 4 shafts, 68 881 shp / 51 386 Kw = 32,00 kts
   Range 1 000nm at 25,00 kts
   Bunker at max displacement = 1 037 tons

Complement:
   382 - 497

Cost:
   £0,675 million / $2,700 million

Distribution of weights at normal displacement:
   Armament: 87 tons, 1,2 %
   Armour: 801 tons, 11,4 %
      - Belts: 384 tons, 5,5 %
      - Torpedo bulkhead: 0 tons, 0,0 %
      - Armament: 30 tons, 0,4 %
      - Armour Deck: 355 tons, 5,1 %
      - Conning Tower: 31 tons, 0,4 %
   Machinery: 2 746 tons, 39,2 %
   Hull, fittings & equipment: 2 503 tons, 35,8 %
   Fuel, ammunition & stores: 781 tons, 11,2 %
   Miscellaneous weights: 82 tons, 1,2 %
      - Torpedoes 20 ton (8+8 reloads)
      - Radio 10 ton (long range not needed in the northen adriatic)
      - Mines 52 ton (always usefull)

Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     4 789 lbs / 2 172 Kg = 46,5 x 5,9 " / 150 mm shells or 0,8 torpedoes
   Stability (Unstable if below 1.00): 1,45
   Metacentric height 3,6 ft / 1,1 m
   Roll period: 11,6 seconds
   Steadiness   - As gun platform (Average = 50 %): 50 %
         - Recoil effect (Restricted arc if above 1.00): 0,16
   Seaboat quality  (Average = 1.00): 1,00

Hull form characteristics:
   Hull has rise forward of midbreak
   Block coefficient: 0,500
   Length to Beam Ratio: 10,63 : 1
   'Natural speed' for length: 23,62 kts
   Power going to wave formation at top speed: 56 %
   Trim (Max stability = 0, Max steadiness = 100): 50
   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:      22,97 ft / 7,00 m
      - Forecastle (20 %):   21,33 ft / 6,50 m
      - Mid (33 %):      21,33 ft / 6,50 m (13,12 ft / 4,00 m aft of break)
      - Quarterdeck (15 %):   13,12 ft / 4,00 m
      - Stern:      13,12 ft / 4,00 m
      - Average freeboard:   15,96 ft / 4,87 m
   Ship tends to be wet forward

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 138,0 %
      - Above water (accommodation/working, high = better): 119,9 %
   Waterplane Area: 19 510 Square feet or 1 813 Square metres
   Displacement factor (Displacement / loading): 99 %
   Structure weight / hull surface area: 83 lbs/sq ft or 404 Kg/sq metre
   Hull strength (Relative):
      - Cross-sectional: 0,99
      - Longitudinal: 1,01
      - Overall: 1,00
   Hull space for machinery, storage, compartmentation is cramped
   Room for accommodation and workspaces is adequate

Bavarian infrastructure seems a bit odd, with a relative large numbers of BPs, but almost no space to build things. Without making any serious calculations it seems to me the cruisers in the 4-6kton range leads to optimum slip usage. :)

Pretty.
But maybe a bit slow, will see if i can push speed one more knot. :)

Slow?!? 32 knots isn't slow for a 6k CL, hell there aren't that many DDs that go 32kts.
For comparison sake the only RL cruisers in the weight bracket that were laid down between 1900-1914 are German and Japanese models, all around 25-28knts, not 33knts. 30+ seems overkill. What ships do we have here in Nverse that would require that much speed?

I think Bavaria's economic situation is more geared towards fending off threats on its land borders than in building up a large fleet.

Ahoj!
Well, the Bavarian army IS one of the most modern and powerful.

Certainly, but having a decent fleet to cover the flanks or rear of the army is a very usefull thing (and it frees up army units from being tied down in cost defence to the same extent). Also, they would be able to upgrade the entire army to Adv in less then two years (from 1908), and still use more then half the BPs on the fleet (with enough money). As Borys observes, they are already very powerfull on the ground.

As I imagine their need, it would in the short term be to go for very fast cruisers and maybe some torpedo boats, and maybe some mine warfare ships (most likely from abroad due to lack of slips) and concentrated on sea denial in the northern Adriatic. IN the longer term adding some larger ships and support ships for fleet-in-the-being and possibly for supporting or supplying armies ashore (or supplying Trieste, as in a war with Austria it is likely to be cut of by land. .
