“But, anyways, I’ve been fishing my whole life and growing up I was told that it’s bad luck to have bananas on the boat. If you had bananas on the boat, you’re going to run into bad weather, you’re not going to catch any fish, and just random bad things. I’ve continued that tradition onward when I go fishing. Can’t be cooked into anything else, or any other forms of bananas. Just no bananas. There are also people though, like this YouTuber I watch who’s a contrarian, who always goes fishing with a banana as a joke”.

Analysis: 

This particular piece of folklore highlights the extreme amount of folkloric content existing around the boating world. Consistently and without fail sailors and seamen in general have proven to be an extremely superstitious subsect of society. While maybe just an unexplainable trait for that group of people, could also be explained by the rich history with boating and seamen activities. Additionally, with so much of what happens out on the water being left up to the whims of mother nature, it makes sense that people would try and explain the unexplainable with superstitions.
