🔍 Key Concepts

• VHF-FM Distress, Safety, and Calling Frequencies used worldwide • Which channel is required to be monitored continuously by most seagoing vessels • Difference between working channels and calling/distress channels

💭 Think About

• Which VHF channel is recognized internationally for distress, safety, and calling at sea? • Are any of the listed channels normally used as routine working channels between ships or between ship and shore? • Which channel would the Coast Guard and most commercial ships be listening to for initial calls and emergencies?

✅ Before You Answer

• Verify which channel is designated as the international distress, safety, and calling channel • Confirm which channels in the list are typically working channels, not mandatory watch channels • Make sure you are thinking about operations at sea, not only in a harbor or on a specific company frequency
