'New' Maori Destroyer

   Miscellaneous weights: 22 tons, 1.7 %

Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):

   Stability (Unstable if below 1.00): 1.30
   Metacentric height 1.3 ft / 0.4 m
   Roll period: 11.0 seconds
   Steadiness   - As gun platform (Average = 50 %): 73 %
         - Recoil effect (Restricted arc if above 1.00): 0.28
   Seaboat quality  (Average = 1.00): 0.91

Hull form characteristics:
   Hull has rise forward of midbreak
   Block coefficient: 0.469
   Length to Beam Ratio: 11.11 : 1
   'Natural speed' for length: 18.11 kts
   Power going to wave formation at top speed: 64 %
   Trim (Max stability = 0, Max steadiness = 100): 80
   Bow angle (Positive = bow angles forward): 5.00 degrees
   Stern overhang: 3.28 ft / 1.00 m
   Freeboard (% = measuring location as a percentage of overall length):

      - Stern:      8.20 ft / 2.50 m
      - Average freeboard:   11.42 ft / 3.48 m
   Ship tends to be wet forward

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 178.0 %
      - Above water (accommodation/working, high = better): 67.7 %
   Waterplane Area: 6,281 Square feet or 584 Square metres
   Displacement factor (Displacement / loading): 65 %
   Structure weight / hull surface area: 27 lbs/sq ft or 130 Kg/sq metre
   Hull strength (Relative):
      - Cross-sectional: 0.50
      - Longitudinal: 0.93
      - Overall: 0.53
   Hull space for machinery, storage, compartmentation is cramped
   Room for accommodation and workspaces is cramped
   Ship has slow, easy roll, a good, steady gun platform
   Poor seaboat, wet and uncomfortable, reduced performance in heavy weather

Four ships in class:
Queen of Hours
Shadow of Fate
Gaze of Revelation
Key and Gate

God ****, those are going to have a fast turning rate... :o

[Valles]

The electric drive is a standard feature of modern Maori designs across all weight classes, and yes, turning ability is one of the reasons that's so. The 1918 class is 'only' competitive with its fellow destroyer designs... but I do, indeed, think that that's saying quite a bit compared to foreign vessels.

[TexanCowboy]

Better than your 2x6'' idea that didn't turn out so well.

[maddox]

I wonder why those have such a range, for a coast defence force.

[Valles]

Plans change.

In a shed, in French Polynesia, a young man is painting a large banner " welcome leberators "

[Valles]

Something like that. ^_^

A typical Maoria DD

Not a bad ship

Plans change.

Why do you think I keep building ships that can handle up to 16" shells at range and escorts that either take it or dish it out?

[maddox]

And here is France, parking 2 obsolete predread harbor queens and a few coast guard cutters in Polynesia .

What's next, sending in an invitation?

Be careful to put the right address on you invitation...others may think it's for them. ;)

Frankly, given the demonstrated impossibility of OOC communication, I'd felt forced to consider not only the always-trivial local forces, but the overall force the French could bring to bear. Even with the mitigating factor of the relative distance of our power centers, the odds are quite poor when viewed in that light.

[maddox]

Valles, I'm well aware of the situation, and the intention of the peacefull Maorians.

Your DD's always had that long range, and you did explain it somewere, You have to sail around your big island, and the amount of ports ain't that plentyfull, so therefor, the long range.

[Valles]

Works for me.
