It certainly is, if nothing else. Keeps one on one's toes. It isn't all like that, but at the best of times, after dark, you can hear the men skylarking and bellowing out songs in the gun room, half of them drunk as lords. I remember my first few weeks as a boy on a ship. It took a long time to be able to sleep easily with the ship rocking so, but I would listen to their hearty little shanties and it would lull me to sleep better than brandy.
