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

The correct answer is based on the understanding of NAVAREAS, which are geographical regions defined for the purpose of maritime safety and navigation, particularly for the dissemination of navigational warnings and emergency information.

A vessel traveling from Miami to Los Angeles via the Panama Canal falls under two NAVAREAS: NAVAREA IV and NAVAREA XII.

NAVAREA IV covers the western Atlantic and the Caribbean Sea, which includes the area around Miami. As the vessel leaves Miami and heads towards the Panama Canal, it remains in NAVAREA IV.

Once the vessel transits through the Panama Canal and enters the Pacific Ocean, it enters NAVAREA XII. This area encompasses the eastern Pacific Ocean, which includes the waters around Los Angeles.

Understanding the geographical coverage of each NAVAREA is essential in selecting the correct regions based on a vessel's route. The other options mix up these regions and do not accurately reflect the trajectory from Miami through the Panama Canal and into Los Angeles.
