Maori Liner

[Valles]

Well, I've mostly been distracted by a bit of news I've been working on for what feels like weeks, but here's the latest iteration of an old and beloved concept.

Mayan, Maoria Liner laid down 1915 (Engine 1912)

Displacement:
   21,617 t light; 22,391 t standard; 38,723 t normal; 51,789 t full load

Dimensions: Length overall / water x beam x draught
   721.37 ft / 688.98 ft x 85.30 ft x 36.09 ft (normal load)
   219.87 m / 210.00 m x 26.00 m  x 11.00 m

Machinery:
   Coal fired boilers, steam turbines,
   Electric motors, 4 shafts, 74,559 shp / 55,621 Kw = 25.00 kts
   Range 7,500nm at 25.00 kts
   Bunker at max displacement = 29,397 tons (100% coal)

Complement:
   1,379 - 1,794

Cost:
   £1.766 million / $7.066 million

Distribution of weights at normal displacement:
   Armament: 0 tons, 0.0 %
   Machinery: 3,270 tons, 8.4 %
   Hull, fittings & equipment: 8,347 tons, 21.6 %
   Fuel, ammunition & stores: 17,106 tons, 44.2 %
   Miscellaneous weights: 10,000 tons, 25.8 %

Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     66,722 lbs / 30,264 Kg = 39.5 x 6 " / 152 mm shells or 5.0 torpedoes
   Stability (Unstable if below 1.00): 1.16
   Metacentric height 5.2 ft / 1.6 m
   Roll period: 15.7 seconds
   Steadiness   - As gun platform (Average = 50 %): 73 %
         - Recoil effect (Restricted arc if above 1.00): 0.00
   Seaboat quality  (Average = 1.00): 1.88

Hull form characteristics:
   Hull has raised forecastle
   Block coefficient: 0.639
   Length to Beam Ratio: 8.08 : 1
   'Natural speed' for length: 26.25 kts
   Power going to wave formation at top speed: 47 %
   Trim (Max stability = 0, Max steadiness = 100): 39
   Bow angle (Positive = bow angles forward): 5.00 degrees
   Stern overhang: 29.53 ft / 9.00 m
   Freeboard (% = measuring location as a percentage of overall length):
      - Stem:      32.81 ft / 10.00 m
      - Forecastle (15 %):   32.81 ft / 10.00 m (24.61 ft / 7.50 m aft of break)
      - Mid (50 %):      24.61 ft / 7.50 m
      - Quarterdeck (15 %):   24.61 ft / 7.50 m
      - Stern:      24.61 ft / 7.50 m
      - Average freeboard:   25.84 ft / 7.88 m

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 56.6 %
      - Above water (accommodation/working, high = better): 151.5 %
   Waterplane Area: 44,569 Square feet or 4,141 Square metres
   Displacement factor (Displacement / loading): 234 %
   Structure weight / hull surface area: 117 lbs/sq ft or 571 Kg/sq metre
   Hull strength (Relative):
      - Cross-sectional: 0.96
      - Longitudinal: 1.48
      - Overall: 1.00
   Hull space for machinery, storage, compartmentation is excellent
   Room for accommodation and workspaces is excellent
   Ship has slow, easy roll, a good, steady gun platform
   Excellent seaboat, comfortable, rides out heavy weather easily

Lotsa steel for a liner... but still nice.

France, the CSA and the UNK all have liners that I know of.

I dunno. I make it 6.25BP for civilian building, so that's not that bad for having a pretty.

[The Rock Doctor]

Turbines make a lot more sense than VTE for a high speed liner, but the amount of coal involved is something.

With eleven metres of draught, you'll also be very limited in available anchorages.

[Valles]

Agreed about the turbines, but IIRC, 'civilian' engines are VTE only.

The draft I essentially forgot to consider, since I was busy getting everything else tolerable for either SS or our actual game rules.

Hmn. Will need at least one more pass, I guess.

[P3D]

Agreed about the turbines, but IIRC, 'civilian' engines are VTE only.

That was changed, the only limit is max 2% weight for armor/guns/mines/depth charges/FC/whatever.

[Valles]

Ah, sweet.

A note: I've kept the original weight figures rather than the year-adjusted ones for a couple-three reasons. First, they're a lot simpler and less of a hassle. Second, the weight of something like a bunk or an armchair is heavily dependent on the materials used to make it; simply choosing wicker over wooden seats for most of the chairs would save many tons. Third, passengers are anything but a mass-intensive cargo, and I'm already spending a great deal of tonnage and/or strength on the very high hull.
