	Ship tends to be wet forward

Ship space, strength and comments:
	Space	- Hull below water (magazines/engines, low = better): 107.5 %
		- Above water (accommodation/working, high = better): 110.3 %
	Waterplane Area: 12,838 Square feet or 1,193 Square metres
	Displacement factor (Displacement / loading): 119 %
	Structure weight / hull surface area: 85 lbs/sq ft or 414 Kg/sq metre
