I'm not sure whether I'll leave it there or not, but I'm tempted...
This is the sort of thing that wastes way too much time - like the frying pan I put on the galley stove in one of the ships with two eggs, each slightly different to the other, and both about 1/8th inch across.
Now a serious question - what is the maritime term for a bathroom with shower, loo, and washbasin etc.?
