U.S. Coast Guard Petty Officer 3rd Class Charles Foy, a boat crew member at Station New Orleans, advises boaters on the importance of having a VHF marine-grade radio onboard on Lake Pontchartrain in New Orleans, Louisiana, Sept. 11, 2025. A cell phone can lose signal over the water, so it is recommended to have alternative means of communication. (U.S. Coast Guard photo by Petty Officer 2nd Class Vincent Moreno)
