What VHF channel is used for emergencies?
In the U.S., VHF Channel 16 is the primary distress, safety, and calling channel. Make the call on 16, then move to a working channel when directed.
What is the difference between Mayday and Pan-Pan?
Mayday is grave and imminent danger (life-threatening). Pan-Pan is urgent but not immediately life-threatening (mechanical failure, medical issue that's stable, etc.).
Does AIS replace radar?
No. AIS only shows vessels transmitting AIS. Radar can show land, weather, and vessels without AIS. AIS is a strong supplement, not a replacement.
Where do I get reliable marine weather?
NOAA marine forecasts are a baseline standard. Learn wind direction, gusts, wave height, and wave period — and always check warnings.
