1. The operator of a motorboat shall not allow any person to ride or sit on the gunwales, decking over the bow, railing, top of seat back or decking over the back of the motorboat while under way, unless such person is inboard of adequate guards or railing provided on the motorboat to prevent a passenger from being lost overboard. As used in this section, the term “adequate guards or railing” means guards or railings having a height parameter of at least six inches but not more than eighteen inches. Nothing in this section shall be construed to mean that passengers or other persons aboard a motorboat cannot occupy the decking over the bow of the boat to moor it to a mooring buoy or to cast off from such a buoy, or for any other necessary purpose. The provisions of this section shall not apply to vessels propelled by sail or vessels propelled by jet motors or propellers operating on a stretch of waterway not created or widened by impoundment.

The provisions of this subsection shall not apply to watercraft that is moored or anchored. The flag required by this subsection shall be visible for three hundred sixty degrees around the horizon when displayed and shall be displayed only when an occupant of the watercraft has left the confines of the watercraft and entered the water. The flag required by this subsection shall not be displayed when the watercraft is engaged in towing any person, but shall be displayed when such person has ceased being towed and has reentered the water.
