If anyone asks you about the monofin, don't mention it is for mermaiding but mention you are working on swim training to learn how to do the dolphin kick or you are practicing freediving with a monofin. Swimmers and freedivers will go to the pool and swim laps while wearing their monofin. If they seem a bit unsure about even allowing you to use the monofin, they likely won't let you have a whole tail.
I would go with this idea.
