What does it mean if you are the stand on vessel in an overtaking situation?

Being the stand-on vessel in an overtaking situation means that you are the vessel that is not required to change course or speed. Essentially, it indicates that another vessel is approaching from behind and intends to pass you. As the stand-on vessel, your primary responsibility is to maintain your current course and speed to provide the overtaking vessel with a clear path to maneuver safely.

This situation is crucial for ensuring predictable navigation on the water, as it allows the overtaking vessel to make a safe passage while you remain steady. Maintaining your course and speed helps prevent confusion and potential collisions during the overtaking maneuver. By doing so, you are upholding navigational rules designed to promote safety and effectiveness in waterway traffic.
