“It is usually the case that at the end of a voyage, where there has been the finest weather, and no disaster, the crew have a wearied and worn-out appearance. They never sleep longer than four hours at a time, and are seldom called without being really in need of more rest. There is no one thing that a sailor thinks more of as a luxury of life on shore, than a whole night’s sleep.” – Richard Henry Dana, Two Years Before the Mast
