What must be submitted to the Coast Guard if a vessel hasn’t communicated in over 48 hours?

When a vessel has not communicated for over 48 hours, it is essential to submit a written confirmation to the Coast Guard. This requirement is in place to ensure that the safety of vessels at sea is effectively monitored and that proper protocol is followed during communication lapses. The written notification provides a clear, documented record of the communication breakdown and allows the Coast Guard to take appropriate action, which may include search and rescue operations or other safety measures.

Written confirmations are crucial because they help establish timelines and details that can be referenced later. In contrast, non-written or verbal notifications lack the permanence and clarity necessary for official reporting, thereby failing to meet the protocol needed in such serious situations. The essence of this requirement reflects the importance of accountability and the need for clear communication channels in maritime safety practices.
