While underway, if you are required to have a radiotelephone, you must maintain a continuous listening watch on which of the following channels?
AI Explanation
The correct answer is D) 16 (156.8 MHz).
According to U.S. Coast Guard regulations, when underway, vessels required to have a radiotelephone must maintain a continuous listening watch on channel 16 (156.8 MHz). This is the international distress, safety, and calling frequency, and is required to be monitored at all times by vessels with radiotelephone equipment.
The other answer choices are incorrect because channels 6, 12, and 14 are not the designated distress, safety, and calling frequency that must be continuously monitored while underway.
