Sailors' superstitions are superstitions particular to sailors or mariners, and which traditionally have been common around the world. Some of these beliefs are popular superstitions, while others are better described as traditions, stories, folklore, tropes, myths, or legends.
The origins of many of these superstitions are based in the inherent risks of sailing, and luck, either good or bad, as well as portents and omens that would be given associative meaning in relation to the life of a mariner, sailor, fisherman, or a crew in general. Even in the 21st century, "fishers and related fishing workers" in the U.S. have the second-most dangerous occupation, trailing only loggers.[1]
