How often should a comparison be made between the current fix and unrelated positioning sources in Coastal Waters?

In navigating coastal waters, it is crucial to maintain an accurate understanding of a vessel's position. Conducting a comparison between the current fix and unrelated positioning sources daily ensures that the information used to ascertain the vessel's location is accurate and reliable. This process enhances safety by providing a means to verify the position against various sources, such as landmarks, GPS readings, or navigational charts.

Daily assessments help to account for any potential discrepancies that might occur due to factors such as currents, winds, or drift. While more frequent checks could be beneficial in certain situations, a daily comparison strikes a balance between diligent monitoring and operational efficiency, allowing crew members to stay informed without overwhelming their workload. Regular verification is a standard practice in maritime operations, aligning with best practices recommended by navigational safety guidelines.
