What is the reporting frequency requirement for the master of a vessel to its owner or agent?

The requirement for the master of a vessel to report to its owner or agent is crucial for ensuring effective communication, safety, and operational efficiency during a vessel's voyage. The correct reporting frequency is every 48 hours. This timeframe allows the master to provide updates on the ship's position, condition, and any other significant developments without overwhelming the owner or agent with excessive communications.

A 48-hour reporting interval strikes a balance between keeping the owner informed and allowing the master enough time to provide meaningful updates. It also aligns with maritime best practices, promoting timely yet manageable communication, which is particularly important during long voyages or in remote areas.

While there might be varying expectations based on different operational contexts or specific agreements, the standard requirement of every 48 hours helps ensure that vessel operations are monitored appropriately while not necessitating constant reporting, which could distract the crew from their duties or lead to communication fatigue.
