The Wreck of the Grosvenor, Volume I by W. Clark Russell

I had slung a cot, although there was a good mahogany bunk in the cabin. No sensible person would sleep in a bunk at sea when he could swing in a hammock or cot. Suppose the bunk is athwart-ship: when the vessel goes about you must shift your pillow; and very often she will go about in your watch below and catch you asleep, so that when you wake you find your feet are in the air, and all the blood in your body in your head. When I first went to sea I slept in a 'thwartship bunk. The ship was taken aback one night when I was asleep, and they came and roared, "All hands shorten sail! " down the booby hatch. I heard the cry and tried to get out of my bed, but my head was jammed to leeward by the weight of my body, and I could not move. Had the ship foundered, I should have gone to the bottom, in bed, helpless. Always after that I slept in a hammock.

The watch on deck had orders to call the captain if a change of wind came; also I knew that the pilot would be up, sniffing about, off and on, through the night: so I turned in properly and slept soundly until two; when, waking up, I drew on my small clothes and went on deck, where I found Duckling mousing about in the moonshine in a pair of yellow flannel drawers, he having, like myself, come up to see if any wind was stirring. He looked like a new kind of monkey in his tight white rig and immense head of hair. "No wind, no wind," he muttered, in a sleepy grumble, and then went below with a run, nearly tumbling, in fact, head over heels down the companion-ladder.
