Hi all,

as I wrote on the Meeting place, I redesigned my Portugals (dimensions are the same)


FPortugal, Iberia BB laid down 1914

Displacement:
30,312 t light; 32,473 t standard; 34,074 t normal; 35,219 t full load
Loading submergence 1,460 tons/feet

Dimensions:
649.61 ft x 104.99 ft x 26.90 ft (normal load)
198.00 m x 32.00 m x 8.20 m

Armament:
12 - 13.78" / 350 mm guns (4 Main turrets x 3 guns, 2 superfiring turrets)
12 - 6.69" / 170 mm guns
Secondary guns mounted low & subject to being washed down in a seaway
8 - 3.94" / 100 mm AA guns
4 - 2.24" / 57 mm guns
Weight of broadside 17,764 lbs / 8,058 kg
5 - 18.9" / 480 mm submerged torpedo tubes

Armour:
Belt 13.78" / 350 mm, upper belt 7.09" / 180 mm, end belts 4.72" / 120 mm
Belts cover 75 % of normal area
Main turrets 13.78" / 350 mm, 2nd casemates 7.87" / 200 mm
AA gun shields 0.98" / 25 mm
Armour deck 3.74" / 95 mm

Machinery:
Oil fired boilers, steam turbines,
Geared drive, 3 shafts, 58,389 shp / 43,558 Kw = 23.50 kts
Range 10,000nm at 10.00 kts

Complement:
1,253 - 1,630

Cost:
£4.125 million / $16.500 million

Distribution of weights at normal displacement:
Armament: 2,220 tons, 6.5 %
Armour: 11,672 tons, 34.3 %
Belts: 3,477 tons, 10.2 %, Armament: 4,659 tons, 13.7 %, Armour Deck: 3,536 tons, 10.4 %
Conning Tower: 0 tons, 0.0 %, Torpedo bulkhead: 0 tons, 0.0 %
Machinery: 2,249 tons, 6.6 %
Hull, fittings & equipment: 14,170 tons, 41.6 %
Fuel, ammunition & stores: 3,763 tons, 11.0 %
Miscellaneous weights: 0 tons, 0.0 %

Metacentric height 5.5

Remarks:
Hull space for machinery, storage & compartmentation is excellent
Room for accommodation & workspaces is excellent
Ship has slow, easy roll, a good, steady gun platform
Good seaboat, rides out heavy weather easily

Estimated overall survivability and seakeeping ability:
Relative margin of stability: 1.01
Shellfire needed to sink: 44,169 lbs / 20,035 Kg = 33.8 x 13.8 " / 350 mm shells
(Approx weight of penetrating shell hits needed to sink ship excluding critical hits)
Torpedoes needed to sink: 4.1
(Approx number of typical torpedo hits needed to sink ship)
Relative steadiness as gun platform: 71 %
(Average = 50 %)
Relative rocking effect from firing to beam: 0.73
Relative quality as seaboat: 1.23

Hull form characteristics:
Block coefficient: 0.650
Sharpness coefficient: 0.44
Hull speed coefficient 'M': 6.13
'Natural speed' for length: 25.49 kts
Power going to wave formation at top speed: 48 %
Trim: 58
(Maximise stabilty/flotation = 0, Maximise steadiness/seakeeping = 100)

Estimated hull characteristics & strength:
Underwater volume absorbed by magazines and engineering spaces: 74.2 %
Relative accommodation and working space: 165.7 %
(Average = 100%)
Displacement factor: 100 %
(Displacement relative to loading factors)
Relative cross-sectional hull strength: 0.97
(Structure weight / hull surface area: 208 lbs / square foot or 1,014 Kg / square metre)
Relative longitudinal hull strength: 1.39
(for 21.33 ft / 6.50 m average freeboard, freeboard adjustment 1.97 ft)
Relative composite hull strength: 1.00

Please correct your post on the infrastructure as well. You should be allowed to edit the summary you provided over there.

Thanks.

cool! didn't know that that works.

will do

thanks
