WW1 destroyer

How does this look?

DD32, Atlantis destroyer laid down 1916

Displacement:
1,243 t light; 1,281 t standard; 1,385 t normal; 1,462 t full load
Loading submergence 167 tons/feet

Dimensions:
324.00 ft x 32.00 ft x 11.00 ft (normal load)
98.76 m x 9.75 m x 3.35 m

Armament:
4 - 4.00" / 102 mm guns
2 - 1.00" / 25 mm AA guns
Weight of broadside 129 lbs / 59 kg
4 - 21.0" / 533.4 mm above water torpedoes

Machinery:
Oil fired boilers, steam turbines,
Direct drive, 2 shafts, 36,312 shp / 27,089 Kw = 33.05 kts
Range 5,000nm at 10.00 kts

Complement:
113 - 147

Cost:
£0.277 million / $1.108 million

Distribution of weights at normal displacement:
Armament: 16 tons, 1.2 %
Machinery: 802 tons, 57.9 %
Hull, fittings & equipment: 405 tons, 29.2 %
Fuel, ammunition & stores: 142 tons, 10.3 %
Miscellaneous weights: 20 tons, 1.4 %

Metacentric height 1.6

Remarks:
Caution: Hull subject to strain in open-sea
Hull space for machinery, storage & compartmentation is cramped
Room for accommodation & workspaces is adequate
Good seaboat, rides out heavy weather easily

Estimated overall survivability and seakeeping ability:
Relative margin of stability: 1.40
Shellfire needed to sink: 355 lbs / 161 Kg = 11.1 x 4.0 " / 102 mm shells
(Approx weight of penetrating shell hits needed to sink ship excluding critical hits)
Torpedoes needed to sink: 0.2
(Approx number of typical torpedo hits needed to sink ship)
Relative steadiness as gun platform: 61 %
(Average = 50 %)
Relative rocking effect from firing to beam: 0.14
Relative quality as seaboat: 1.21

Hull form characteristics:
Block coefficient: 0.425
Sharpness coefficient: 0.30
Hull speed coefficient 'M': 8.88
'Natural speed' for length: 18.00 kts
Power going to wave formation at top speed: 69 %
Trim: 51
(Maximise stabilty/flotation = 0, Maximise steadiness/seakeeping = 100)

Estimated hull characteristics & strength:
Underwater volume absorbed by magazines and engineering spaces: 197.2 %
Relative accommodation and working space: 115.7 %
(Average = 100%)
Displacement factor: 49 %
(Displacement relative to loading factors)
Relative cross-sectional hull strength: 0.51
(Structure weight / hull surface area: 34 lbs / square foot or 166 Kg / square metre)
Relative longitudinal hull strength: 1.65
(for 16.00 ft / 4.88 m average freeboard, freeboard adjustment 5.80 ft)
Relative composite hull strength: 0.58

Look?

Well, no idea how it "looks" without a drawing but its stats seem to be quite good. :o)

Hmmm.....

Well, when you really ask for it..... It could have a greater range. though, but on the other hand you sealines are not as strechted as mine are...

Just a thought. It is one of the best DD designs I´ve seen so far.

well

I tried basing it on the British V/W class destroyers but i couldn't get the speed as high as them in 1916 instead of the year the British ships were built (1918).
