NEW YORK -- A group of swimmers in Brooklyn say they're concerned about boats and jet skis getting to close, so they found a loophole to help keep the waters safe.Within sight of the beach, Joe Koppelman jumped off a boat in head-to-toe scuba gear to find a cinderblock buried in the sand. Once located 17 feet under the surface, he attached a rope and installed a buoy with a sign: 'Minimum Motocraft Distance 500 ft.''It's a little bit like bicycling in Manhattan.
'Buoys can be useful for indicating the distance to the shore; however, historically we have observed that some swimmers view the buoys as goals to reach, causing them to swim out to unsafe distances. Due to safety concerns, we have not used buoys in this area for this purpose since the 1990s,' a Parks spokesperson told CBS New York in a statement.
