A vessel on a voyage between Miami and Los Angeles via the Panama Canal would be operating in which NAVAREA(s)?

Correct Answer: Option B — IV and XII

A transit from Miami to Los Angeles via the Panama Canal requires crossing from the Atlantic to the Pacific. The vessel departs NAVAREA IV (Western North Atlantic) and enters NAVAREA XII (Eastern Pacific) upon passing through the canal, necessitating the monitoring of MSI broadcasts for both distinct geographic regions.
