Distribution of weights at normal displacement:
Armament: 322 tons, 1.1 %
Armour: 14,912 tons, 51.0 %
Belts: 8,813 tons, 30.2 %, Armament: 1,714 tons, 5.9 %, Armour Deck: 2,672 tons, 9.1 %

Hull, fittings & equipment: 6,858 tons, 23.5 %
Fuel, ammunition & stores: 1,974 tons, 6.8 %
Miscellaneous weights: 1,600 tons, 5.5 %
Metacentric height 3.3
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
Excellent seaboat, comfortable and able to fight her guns in the heaviest weather
Estimated overall survivability and seakeeping ability:
Relative margin of stability: 0.97
Shellfire needed to sink: 28,537 lbs / 12,944 Kg = 92.9 x 8.5 " / 216 mm shells
(Approx weight of penetrating shell hits needed to sink ship excluding critical hits)
Torpedoes needed to sink: 3.6
(Approx number of typical torpedo hits needed to sink ship)
Relative steadiness as gun platform: 85 %
(Average = 50 %)
Relative rocking effect from firing to beam: 0.43
Relative quality as seaboat: 1.88
Hull form characteristics:
Block coefficient: 0.550
Sharpness coefficient: 0.36
Hull speed coefficient 'M': 6.82
'Natural speed' for length: 26.20 kts
Power going to wave formation at top speed: 50 %
Trim: 45
(Maximise stabilty/flotation = 0, Maximise steadiness/seakeeping = 100)
Estimated hull characteristics & strength:
Underwater volume absorbed by magazines and engineering spaces: 73.8 %
Relative accommodation and working space: 183.5 %
(Average = 100%)
Displacement factor: 112 %
(Displacement relative to loading factors)
Relative cross-sectional hull strength: 0.73
(Structure weight / hull surface area: 105 lbs / square foot or 510 Kg / square metre)
Relative longitudinal hull strength: 1.40
(for 29.80 ft / 9.08 m average freeboard, freeboard adjustment 11.04 ft)
Relative composite hull strength: 0.78
The Hailey Class landing ship can approach a beach, close enough that it can deploy its frontal ramp. If there is heavy fire, troops can disembark onto smaller landing craft from the rear and sides, while the Hailey provides covering fire with her 8.5", 2.5", 39.5mm, and 7.56mm MG's.
The Transport can carry a maximum of 1 Portugese Division (10,000 Troops + Supplies). The ship can also carry armoured cars, artillery, 1600t of supplies/ammunition, and other such items. The weight of a fully equiped division is 1275t, leaving ample room for more ammunition, or for the troops to spread out a bit.
The Transport can take a beating, It would take over 90 216mm shells to sink it, and several torpedoes. The Machine guns on Deck are protected from small arms fire, upto an inch thick. 7.56mm MG rounds will not penetrate the armour, allowing the Hailey's MG's to clear the beach of enemy soldiers unhindered.
