How much would this vessel cost by the newer tender rules? I can't seem to figure it out.
Approximately 12,000 Tons of Support Ability.

Large Fleet Tender laid down 1915 (Engine 1912)

   654.23 ft / 630.00 ft x 86.00 ft x 22.50 ft (normal load)
   199.41 m / 192.02 m x 26.21 m  x 6.86 m

Armament:
      4 - 4.02" / 102 mm guns in single mounts, 38.58lbs / 17.50kg shells, 1915 Model
     Quick firing guns in deck mounts
     on side ends, evenly spread
      4 - 1.85" / 47.0 mm guns in single mounts, 3.00lbs / 1.36kg shells, 1915 Model
     Quick firing guns in deck mounts
     on side, all amidships, 2 raised mounts - superfiring
   Weight of broadside 166 lbs / 75 kg
   Shells per gun, main battery: 200

Machinery:
   Coal fired boilers, complex reciprocating steam engines,
   Direct drive, 2 shafts, 8,289 ihp / 6,184 Kw = 15.00 kts
   Range 34,230nm at 10.00 kts
   Bunker at max displacement = 11,012 tons (100% coal)

Complement:
   841 - 1,094

Cost:
   £0.820 million / $3.281 million

Distribution of weights at normal displacement:
   Armament: 18 tons, 0.1 %
   Machinery: 549 tons, 2.7 %
   Hull, fittings & equipment: 5,773 tons, 28.8 %
   Fuel, ammunition & stores: 6,538 tons, 32.6 %
   Miscellaneous weights: 7,150 tons, 35.7 %

Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     39,894 lbs / 18,096 Kg = 1,232.1 x 4.0 " / 102 mm shells or 5.1 torpedoes
   Stability (Unstable if below 1.00): 1.25
   Metacentric height 6.0 ft / 1.8 m
   Roll period: 14.7 seconds
   Steadiness   - As gun platform (Average = 50 %): 55 %
         - Recoil effect (Restricted arc if above 1.00): 0.00
   Seaboat quality  (Average = 1.00): 1.38

Hull form characteristics:
   Hull has raised forecastle, raised quarterdeck
   Block coefficient: 0.575
   Length to Beam Ratio: 7.33 : 1
   'Natural speed' for length: 25.10 kts
   Power going to wave formation at top speed: 23 %
   Trim (Max stability = 0, Max steadiness = 100): 40
   Bow angle (Positive = bow angles forward): 10.00 degrees
   Stern overhang: 20.00 ft / 6.10 m
   Freeboard (% = measuring location as a percentage of overall length):
      - Stem:      24.00 ft / 7.32 m
      - Forecastle (15 %):   21.00 ft / 6.40 m (14.00 ft / 4.27 m aft of break)
      - Mid (50 %):      14.00 ft / 4.27 m
      - Quarterdeck (15 %):   21.00 ft / 6.40 m (14.00 ft / 4.27 m before break)
      - Stern:      23.00 ft / 7.01 m
      - Average freeboard:   16.43 ft / 5.01 m
   Ship tends to be wet forward

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 49.6 %
      - Above water (accommodation/working, high = better): 122.7 %
   Waterplane Area: 38,709 Square feet or 3,596 Square metres
   Displacement factor (Displacement / loading): 239 %
   Structure weight / hull surface area: 113 lbs/sq ft or 551 Kg/sq metre
   Hull strength (Relative):
      - Cross-sectional: 1.20
      - Longitudinal: 0.94
      - Overall: 1.00
   Hull space for machinery, storage, compartmentation is excellent
   Room for accommodation and workspaces is excellent
   Good seaboat, rides out heavy weather easily

Misc. Weights(7,150+5000 Tons):
Short Range Wireless Set
50 Tons Dual Long Range Wireless Sets
200 Tons extra Ships Boats/Barges
200 Tons for Cranes and Access Hoists

The Rock Doctor

Calculate the total non-functional miscellaneous weight - in this case, probably only "Weight reserves" and any coal being carried in addition to your bunkerage.

Subtract this figure from your BP.  The result is your cash cost.

Divide the cash cost by four, as if calculating a mercantile build.  The result is your BP cost.

Example:

-Ship weights 13,000 t and has 3,000 t of non-functional miscellaneous weight (all of it as additional coal simmed with miscellaneous weight).

-13,000 - 3,000 = 10,000 = $10 cash cost.

-$10/4 = 2.50 BP cost
