	Ship tends to be wet forward

Ship space, strength and comments:
	Space	- Hull below water (magazines/engines, low = better): 114.1 %
		- Above water (accommodation/working, high = better): 83.5 %
	Waterplane Area: 17,704 Square feet or 1,645 Square metres
	Displacement factor (Displacement / loading): 99 %
	Structure weight / hull surface area: 122 lbs/sq ft or 597 Kg/sq metre
	Hull strength (Relative):
		- Cross-sectional: 0.89
		- Longitudinal: 2.76
		- Overall: 1.00
	Cramped machinery, storage, compartmentation space
	Cramped accommodation and workspace room
	Ship has slow, easy roll, a good, steady gun platform
	Good seaboat, rides out heavy weather easily

Notes: Springsharp can't handle my relatively complex armour layout, so I've averaged the height and thickness for all upper belts to get the weight. The secondary and tertiary magazines, as well as the primary handling/ready rooms and part of the boilers, are above the waterline, but Springsharp doesn't simulate this either, so ignore the minimum main belt length warning. The tl;dr: is that she has a 11" belt.
