Which statement describes a limitation of cellular telephone use in a maritime emergency?

• A. Cellular conversations cannot be heard by other boaters
• B. Cellular calls are always traced instantly
• C. Cellular service is free at sea
• D. Cellular devices always have full battery life at sea

Answer: (A)

The main idea is that cellular phones don’t provide a broadcast distress channel at sea. Cellular conversations are private between you and the person you’re speaking with, so nearby boats cannot hear what you’re saying unless the other party relays it or you switch to a radio. In a maritime emergency, you often need to alert multiple vessels or coast stations quickly, which is why VHF radiocommunication is used for broad or public distress calls. That makes the statement about cellular conversations not being heard by other boaters the best description of a limitation: you can’t rely on a cellular call to reach nearby responders, limiting practical emergency communications. The other statements aren’t accurate descriptions of how cellular use works at sea—cell service isn’t free there, isn’t instantly traced, and battery life isn’t guaranteed.
