Which is a limitation of using a cellular telephone in a maritime emergency?

• A. Cellular limits communications to point-to-point communications
• B. Cellular conversations can be heard by other boaters
• C. Cellular phone use has unlimited range
• D. Cellular devices operate without power

Answer: (A)

Cellular phones rely on land-based towers, so you’re limited to point-to-point communications within the coverage area. In a maritime emergency, that matters because you may be offshore with no nearby towers, and even within range you’re typically connecting to just one other party rather than broadcasting to multiple responders. That makes cellular less reliable for urgent, wide-area distress calls compared with marine radios. The other options don’t capture this fundamental limitation: conversations being heard by other boaters isn’t the core constraint, cellular range isn’t unlimited, and these devices don’t operate without power.
