Overall survivability and seakeeping ability:
	Survivability (Non-critical penetrating hits needed to sink ship):
	  286 lbs / 130 Kg = 7.1 x 4.3 " / 110 mm shells or 0.2 torpedoes
	Stability (Unstable if below 1.00): 1.31
	Metacentric height 1.5 ft / 0.5 m
	Roll period: 11.1 seconds
	Steadiness	- As gun platform (Average = 50 %): 39 %
			- Recoil effect (Restricted arc if above 1.00): 0.12
	Seaboat quality  (Average = 1.00): 0.59

Hull form characteristics:
	Hull has raised forecastle,
	  a normal bow and a round stern
	Block coefficient (normal/deep): 0.409 / 0.418
	Length to Beam Ratio: 8.00 : 1
	'Natural speed' for length: 16.20 kts
	Power going to wave formation at top speed: 66 %
	Trim (Max stability = 0, Max steadiness = 100): 50
	Bow angle (Positive = bow angles forward): 4.00 degrees
	Stern overhang: -3.28 ft / -1.00 m
	Freeboard (% = length of deck as a percentage of waterline length):
				Fore end,	 Aft end
	   - Forecastle:	20.00 %,  13.12 ft / 4.00 m,  13.12 ft / 4.00 m
	   - Forward deck:	30.00 %,  9.84 ft / 3.00 m,  9.84 ft / 3.00 m

	   - Average freeboard:		10.50 ft / 3.20 m
	Ship tends to be wet forward

Ship space, strength and comments:
	Space	- Hull below water (magazines/engines, low = better): 184.8 %
		- Above water (accommodation/working, high = better): 2.4 %
	Waterplane Area: 5,329 Square feet or 495 Square metres
	Displacement factor (Displacement / loading): 51 %
	Structure weight / hull surface area: 33 lbs/sq ft or 161 Kg/sq metre
