What is the meaning of the term 'not to impede' in the context of collision regulations?

The term 'not to impede' in the context of collision regulations specifically refers to the responsibility of vessels to avoid hindering the safe passage of other vessels that have a legal right of way. This often applies in scenarios where vessels are constrained by their draft, meaning they cannot navigate freely due to depth restrictions or other limitations.

In essence, a vessel must take necessary measures to ensure it does not interfere with the navigation of another vessel that is limited in its ability to maneuver. This is crucial for maintaining safety at sea and ensuring the efficient passage of ships, particularly those constrained by their navigation limits. Therefore, recognizing the importance of this regulation is vital for avoiding accidents and ensuring smooth traffic in waterways.

The other options do not accurately capture the concept of 'not to impede' as used in the collision regulations. For example, simply maintaining a course without deviation does not address the obligation to respect the rights of vessels constrained by their draft, and navigating at all costs disregards the safety considerations inherent in maritime navigation.
