The original concept for the Ger/CS/1905 design

This is the original specification for the Ger/CS/1905 scout cruiser:

Ger/CS/1905  365ft x 37ft x 12ft   Cp=0.56  Cm=0.85
Standard displacement=2,200 tons  37 knots  oil fuel
Armament: 6-4in QF guns, 2-18in TT
Cost=£223,000

The 37 knot speed was not feasible under any circumstances with the current version of Springsharp. This is what was possible, with which I am reasonably happy:

Ger/CS/1905, Germany Scout Cruiser laid down 1905 (Engine 1950)

Displacement:
 2,146 t light; 2,213 t standard; 2,425 t normal; 2,595 t full load

Dimensions: Length overall / water x beam x draught

 111.25 m / 111.25 m x 11.28 m  x 3.96 m

Armament:
      2 - 4.00" / 102 mm guns in single mounts, 32.00lbs / 14.51kg shells, 1905 Model
   Quick firing guns in deck mounts with hoists
   on centreline ends, evenly spread
      4 - 4.00" / 102 mm guns in single mounts, 32.00lbs / 14.51kg shells, 1905 Model
   Quick firing guns in deck mounts with hoists
   on side, all amidships
 Weight of broadside 192 lbs / 87 kg
 Shells per gun, main battery: 150
 2 - 18.0" / 457.2 mm above water torpedoes

Machinery:
 Oil fired boilers, steam turbines, 
 Direct drive, 2 shafts, 73,162 shp / 54,579 Kw = 36.00 kts
 Range 4,500nm at 15.00 kts
 Bunker at max displacement = 382 tons

Complement:
 172 - 224

Cost:
 £0.293 million / $1.170 million

Distribution of weights at normal displacement:
 Armament: 24 tons, 1.0 %
 Machinery: 1,409 tons, 58.1 %
 Hull, fittings & equipment: 712 tons, 29.4 %
 Fuel, ammunition & stores: 279 tons, 11.5 %
 Miscellaneous weights: 0 tons, 0.0 %

Overall survivability and seakeeping ability:
 Survivability (Non-critical penetrating hits needed to sink ship):
   593 lbs / 269 Kg = 18.5 x 4.0 " / 102 mm shells or 0.3 torpedoes
 Stability (Unstable if below 1.00): 1.41
 Metacentric height 2.0 ft / 0.6 m
 Roll period: 10.9 seconds
 Steadiness - As gun platform (Average = 50 %): 57 %
   - Recoil effect (Restricted arc if above 1.00): 0.25
 Seaboat quality  (Average = 1.00): 1.13

Hull form characteristics:
 Hull has rise forward of midbreak
 Block coefficient: 0.483
 Length to Beam Ratio: 9.86 : 1
 'Natural speed' for length: 19.10 kts
 Power going to wave formation at top speed: 73 %
 Trim (Max stability = 0, Max steadiness = 100): 50
 Bow angle (Positive = bow angles forward): 0.00 degrees
 Stern overhang: -2.00 ft / -0.61 m
 Freeboard (% = measuring location as a percentage of overall length):
    - Stem:  26.00 ft / 7.92 m
    - Forecastle (20 %): 25.00 ft / 7.62 m
    - Mid (36 %):  25.00 ft / 7.62 m (17.00 ft / 5.18 m aft of break)
    - Quarterdeck (15 %): 17.00 ft / 5.18 m
    - Stern:  17.00 ft / 5.18 m
    - Average freeboard: 19.96 ft / 6.08 m

Ship space, strength and comments:
 Space - Hull below water (magazines/engines, low = better): 195.2 %
  - Above water (accommodation/working, high = better): 172.3 %
 Waterplane Area: 8,865 Square feet or 824 Square metres
 Displacement factor (Displacement / loading): 66 %
 Structure weight / hull surface area: 34 lbs/sq ft or 166 Kg/sq metre
 Hull strength (Relative):
  - Cross-sectional: 0.42
  - Longitudinal: 3.70
  - Overall: 0.53
 Hull space for machinery, storage, compartmentation is cramped
 Room for accommodation and workspaces is excellent
