After the initial position call to SEAWAY NEW CASTLE, which VHF-FM channel should be guarded?

The correct answer is to guard VHF-FM channel 16 after the initial position call to SEAWAY NEW CASTLE. Channel 16 is recognized internationally as the distress, safety, and calling channel. It serves as the primary means for vessels to initiate communication for emergencies as well as to establish contact with other vessels, bridge authorities, and harbormasters.

After making the initial contact with SEAWAY NEW CASTLE, maintaining a watch on this channel ensures that any critical communications can be received promptly. This practice aligns with maritime communication protocols intended to enhance navigation safety and awareness on busy waterways like those surrounding Lake Ontario.

While channels such as 12, 13, and 11 may have specific uses, especially in localized communications or for certain navigational purposes, they do not serve as the designated emergency or distress channel, which is critical for maintaining safety on the water.
