Before entering a restricted channel, which procedure should you conduct?

• A. Weather briefing
• B. Security broadcast
• C. Engine room check
• D. Crew muster

Answer: (B)

When you’re about to enter a restricted channel, you need to establish your position and intent so others can anticipate your movements and any security concerns can be monitored. A security broadcast is the standard way to do this: you announce who you are, where you are, your course and speed, and your intended entry plan to nearby vessels and authorities. This coordination helps prevent misinterpretation or collisions and allows quick notice of any security issues or changes in plan.

Weather briefing is useful for navigation planning but doesn’t fulfill the immediate need to communicate your entry and security status. An engine room check and crew muster are internal readiness actions or emergency procedures, not the procedure for entering restricted waters. The security broadcast directly supports safe and secure transit through restricted channels by keeping everyone informed.
