No bananas on the boat

There are many theories on why people believe bananas are bad luck for a boat. One superstition is that boats carrying bananas don’t catch fish. The origin of this belief dates back to the Caribbean trade of the 1700s. The wooden sailing boats of that time had to move quickly to deliver bananas before they spoiled, and fishermen had a hard time trolling for fish on such fast-moving boats, which is how the superstition came about. Another superstition that originated during that time is that bananas will cause a boat to sink. This belief developed after many boats never made it to their destinations, and all of the doomed boats were carrying bananas.

Suitcases onboard is a fishing boat no-no as well. Even when camera crew boarded crab boats to film Discovery Channel’s reality series “Deadliest Catch,” they were asked to leave their equipment suitcases on the dock [source: Deadliest Catch].
