Remarks:
Hull space for machinery, storage & compartmentation is adequate
Room for accommodation & workspaces is adequate
Ship has slow, easy roll, a good, steady gun platform
Estimated overall survivability and seakeeping ability:
Relative margin of stability: 1.15
Shellfire needed to sink: 17,356 lbs / 7,873 Kg = 61.4 x 8.3 " / 210 mm shells
(Approx weight of penetrating shell hits needed to sink ship excluding critical hits)
Torpedoes needed to sink: 1.9
(Approx number of typical torpedo hits needed to sink ship)
Relative steadiness as gun platform: 75 %
(Average = 50 %)
Relative rocking effect from firing to beam: 0.46
Relative quality as seaboat: 1.10
Hull form characteristics:
Block coefficient: 0.520
Sharpness coefficient: 0.34
Hull speed coefficient 'M': 8.13
'Natural speed' for length: 25.62 kts
Power going to wave formation at top speed: 55 %
Trim: 68
(Maximise stabilty/flotation = 0, Maximise steadiness/seakeeping = 100)
Estimated hull characteristics & strength:
Underwater volume absorbed by magazines and engineering spaces: 96.0 %
Relative accommodation and working space: 120.0 %
(Average = 100%)
Displacement factor: 117 %
(Displacement relative to loading factors)
Relative cross-sectional hull strength: 0.98
(Structure weight / hull surface area: 118 lbs / square foot or 575 Kg / square metre)
Relative longitudinal hull strength: 1.16
(for 19.69 ft / 6.00 m average freeboard, freeboard adjustment 3.25 ft)
Relative composite hull strength: 1.00
the 100 mm are twins, not yet in AA mountings, 2 either side, 1 each superimposed over the quads
the quads simply save loads! of weight (before you ask, Hooman :-)
57 mm are triplets, at the mom still manually loaded
side armour is 15° inclined
now weight for floatplanes has reasons in Iberian naval doctrine that will become clear
2 funnels, 1 main command tower
seakeeping is intentionally low, after all the Armada operates in rather pleasant waters...
