What is a swimming area regulatory marker?

Answer 1

I've been to the beach and these are the markers you'll usually see farther out in the body of water. Think of this marker as a "No Swimming beyond this point" sign. These markers are usually set out in the deeper water. I don't know the exact measurement of where they'd be placed but my guess would be they'd set it out on the edge of where it just gets deeper than 5 ft. No one is allowed outside those markers and no boats are allowed inside those markers. These markers show the public of where it's too deep for them to swim safely and these markers show the boats where the swimming zone is.
