Overall survivability and seakeeping ability:
	Survivability (Non-critical penetrating hits needed to sink ship):
	  23,598 lbs / 10,704 Kg = 14.0 x 15.0 " / 381 mm shells or 3.0 torpedoes

	Metacentric height 9.7 ft / 2.9 m
	Roll period: 12.0 seconds
	Steadiness	- As gun platform (Average = 50 %): 51 %
			- Recoil effect (Restricted arc if above 1.00): 0.21
	Seaboat quality  (Average = 1.00): 1.01

Hull form characteristics:
	Hull has a flush deck,
	  a normal bow and a cruiser stern
	Block coefficient (normal/deep): 0.613 / 0.625
	Length to Beam Ratio: 8.89 : 1
	'Natural speed' for length: 28.06 kts
	Power going to wave formation at top speed: 57 %
	Trim (Max stability = 0, Max steadiness = 100): 51
	Bow angle (Positive = bow angles forward): 30.00 degrees
	Stern overhang: 6.56 ft / 2.00 m
	Freeboard (% = length of deck as a percentage of waterline length):
				Fore end,	 Aft end
	   - Forecastle:	9.50 %,  58.73 ft / 17.90 m,  43.64 ft / 13.30 m
	   - Forward deck:	30.00 %,  43.64 ft / 13.30 m,  18.04 ft / 5.50 m

	   - Average freeboard:		24.93 ft / 7.60 m

Ship space, strength and comments:
	Space	- Hull below water (magazines/engines, low = better): 137.8 %
		- Above water (accommodation/working, high = better): 232.5 %
	Waterplane Area: 51,625 Square feet or 4,796 Square metres
	Displacement factor (Displacement / loading): 115 %
	Structure weight / hull surface area: 131 lbs/sq ft or 637 Kg/sq metre
	Hull strength (Relative):
		- Cross-sectional: 1.00
		- Longitudinal: 1.03
		- Overall: 1.00
	Cramped machinery, storage, compartmentation space
	Excellent accommodation and workspace room

15" /42 Mark I - maximum range 33.380m @ 30 deg
4"/50 BL Mark VII - Anti-torpedo boat defense to 10.600m

Firing arcs: 4 gun broadside, 2 guns fore and aft.
Casemates have 200 degree traverse, with a 20 degree overlapping broadside fire arc on each side. This is sufficient for bombardment purposes.

Speed: 35.5 knots - faster than all existing destroyers.
The current L-class destroyer has a maximum speed of 29 knots, and the new M-class destroyers currently under construction have a maximum speed of 34 knots.

Underwater Protection: Achronologicially derived from Tennessee class design, the greatest underwater protection in history.
