🔍 Key Concepts

• VHF marine radio channels and their primary purposes (bridge-to-bridge, distress/safety, port operations, weather, etc.) • Difference between Coast Guard safety broadcasts and routine ship-to-ship or ship-to-shore traffic • How "A" channels (like 22A, 9A) are commonly used in U.S. waters

💭 Think About

• First, recall which channel is used as the main international calling and distress channel, and then which channel the Coast Guard often shifts you to for safety information. • Think about which channel number you associate with bridge-to-bridge communications between ships; that one is NOT typically used for routine weather broadcasts. • Among the options, identify which one is commonly paired with Channel 16 during Coast Guard communications, especially for detailed safety or weather information.

✅ Before You Answer

• Verify which channel the Coast Guard typically announces on one channel, then tells you to switch to another for the full message. • Check your memory of standard U.S. VHF recreational and commercial traffic channels vs. dedicated safety/information channels. • Confirm which of the listed channels is specifically associated with Coast Guard information and weather broadcasts, rather than normal ship-to-ship or port ops traffic.
