Overall survivability and seakeeping ability:
	Survivability (Non-critical penetrating hits needed to sink ship):
	  486 lbs / 220 Kg = 7.2 x 5.1 " / 130 mm shells or 0.3 torpedoes
	Stability (Unstable if below 1.00): 1.46
	Metacentric height 2.2 ft / 0.7 m
	Roll period: 10.6 seconds
	Steadiness	- As gun platform (Average = 50 %): 39 %
			- Recoil effect (Restricted arc if above 1.00): 0.34
	Seaboat quality  (Average = 1.00): 0.50

Hull form characteristics:
	Hull has a flush deck,
	  a normal bow and a round stern
	Block coefficient (normal/deep): 0.454 / 0.471
	Length to Beam Ratio: 10.25 : 1
	'Natural speed' for length: 19.49 kts
	Power going to wave formation at top speed: 66 %
	Trim (Max stability = 0, Max steadiness = 100): 61
	Bow angle (Positive = bow angles forward): 19.70 degrees
	Stern overhang: 2.62 ft / 0.80 m
	Freeboard (% = length of deck as a percentage of waterline length):
				Fore end,	 Aft end
	   - Forecastle:	17.50 %,  18.04 ft / 5.50 m,  14.44 ft / 4.40 m
