Now folks, if somebody tried to sell you _this_ as a treaty cruiser I would agree that you had grounds to get a mite suspicious ;->

Miscellaneous weights: 0 tons, 0.0 %

Metacentric height 3.3

Remarks:
Hull space for machinery, storage & compartmentation is adequate
Room for accommodation & workspaces is excellent
Ship has slow, easy roll, a good, steady gun platform

Estimated overall survivability and seakeeping ability:
Relative margin of stability: 1.00
Shellfire needed to sink: 23,642 lbs / 10,724 Kg = 83.7 x 8.3 " / 210 mm shells
(Approx weight of penetrating shell hits needed to sink ship excluding critical hits)
Torpedoes needed to sink: 3.7
(Approx number of typical torpedo hits needed to sink ship)
Relative steadiness as gun platform: 70 %
(Average = 50 %)
Relative rocking effect from firing to beam: 0.56
Relative quality as seaboat: 1.06

Hull form characteristics:
Block coefficient: 0.510
Sharpness coefficient: 0.34
Hull speed coefficient 'M': 8.15
'Natural speed' for length: 27.17 kts
Power going to wave formation at top speed: 53 %
Trim: 66
(Maximise stabilty/flotation = 0, Maximise steadiness/seakeeping = 100)

Estimated hull characteristics & strength:
Underwater volume absorbed by magazines and engineering spaces: 90.3 %
Relative accommodation and working space: 122.6 %
(Average = 100%)
Displacement factor: 113 %
(Displacement relative to loading factors)
Relative cross-sectional hull strength: 1.00
(Structure weight / hull surface area: 140 lbs / square foot or 686 Kg / square metre)
Relative longitudinal hull strength: 1.08
(for 21.33 ft / 6.50 m average freeboard, freeboard adjustment 3.71 ft)
Relative composite hull strength: 1.01

I think with this design there would be no way to hide her true size. She is definately quite balanced though.

hmmm...
220 meters multiplied by 22 meters multiplied by 7 meters multiplied by... lets keep the BC at 0.48...
That divided by 1.0161 is 16004 tons. Normal displacement. They say the range is about 15000 NM at 15, thus it would require some 3,200 tons of fuel... so that would put the standard displacement under 13,000 tons!
Known for their honesty, the Japanese observers measuring the Iberian Cruiser have come to the conclusion that the ship is below the 13,000 ton limit. Armor is probably no better than paper though.

(Note: the observers were last seen loading several crates with gold aboard their ship)
