Women are not allowed on board on commercial fishing boats
The most common superstition is that women are bad luck on commercial fishing boats. “It is bad luck to have any women on board unless she is a really good cook.” My informant stated that is really the only reason to break the rule. My informant stated that one time a fisherman’s girlfriend was on board for a trip and one of the fisherman sustained a broken ankle; the woman was blamed for this incident. My informant was told about this as the captain brought his wife aboard once, and the boat actually hit the sand, the captain’s wife was soon blamed for this.
My informant stated that this superstition basically spread throughout lineage and cannot really explain the cause of this superstition. He also stated that his boss cannot focus when his wife is onboard, and thus he compares it to bringing your wife to work everyday. This is interestingly only on commercial fishing boats. Another incident where this folklore became prevalent was on the television show, The Deadliest Catch. There was a story about how there was a problem with some of on-site women producers being on the commercial fishing boat.
My analysis of this would be that sailors and fisherman call their boats a “she” or “her,” thus the only woman that should be in their life while they are at sea, should be their boat.
