A vessel operating in the Eastern Pacific would be operating in which NAVAREA?

A vessel operating in the Eastern Pacific is assigned to NAVAREA XII. NAVAREAs are regions of maritime safety information used globally to organize maritime navigational and safety messages. Each NAVAREA corresponds to specific oceanic areas that are monitored and serviced by designated National Coordinators.

NAVAREA XII encompasses the Eastern Pacific, specifically relating to the area of responsibility for broadcasting navigational warnings, maritime safety information, and related communications. This information is vital for ensuring safe navigation in the waters of that region.

The other options refer to different regions: NAVAREA X covers the South-West Pacific, NAVAREA XI is assigned to the Central Pacific, and NAVAREA IV pertains to the Central and Southern Atlantic Ocean. Therefore, choosing NAVAREA XII is appropriate for a vessel navigating in the Eastern Pacific.
