Overall survivability and seakeeping ability:
	Survivability (Non-critical penetrating hits needed to sink ship):
	  76 lbs / 34 Kg = 5,9 x 3,0 " / 75 mm shells or 0,1 torpedoes
	Stability (Unstable if below 1.00): 1,60
	Metacentric height 1,0 ft / 0,3 m
	Roll period: 8,4 seconds
	Steadiness	- As gun platform (Average = 50 %): 53 %
			- Recoil effect (Restricted arc if above 1.00): 0,18
	Seaboat quality  (Average = 1.00): 1,76

Hull form characteristics:
	Hull has a flush deck
	Block coefficient: 0,300
	Length to Beam Ratio: 10,33 : 1
	'Natural speed' for length: 14,26 kts
	Power going to wave formation at top speed: 63 %
	Trim (Max stability = 0, Max steadiness = 100): 30
