Please report back with results after a year. Be sure to include the playlist!From a long ago article I read (Popular Science).
The Navy pulled a ship our for bottom paint due to large scale barnacle cover. There was a large area of bottom near a porthole free of any barnacles. They investigated and found that a couple of very young seamen were bunked it that area and kept a radio playing rock all the time. Apparently the vibrations from the continuous music extended to the hull area and made it impossible for barnacles to attach with all that vibration. It was a pretty extensive two page article.
I guess barnacles do not like rock music.
I guess a loud radio playing rock music all the time inside boat will make barnacles sick and leave boat alone. I am going to try it on my sailboat this year. I've got an old radio I can leave inside boat full time. Hopefully it will keep the damn slime off also.
