Wonder how long it will take for the geniuses in the field to figure out that if you create a barrier out of booms, along the width of the beach, you've now effectively blocked off the entire area.
You could effectively totally block several miles of beach by the simple placement of a few 100 feet of boom on either end. No different than a police barrier or crime scene tape. "Do not pass".
Except that's not what they're selling us here, supposedly. 65 feet my ass.
