What does Rule 9 state about a vessel's position in a narrow channel?

Rule 9 of the International Regulations for Preventing Collisions at Sea (COLREGs) addresses the conduct of vessels navigating in narrow channels and straits. The fundamental principle established by Rule 9 is that a vessel shall keep near the outer limit of the channel on her starboard side. This guideline is critical for ensuring safe navigation and minimizing the risk of collisions in confined waters, where vessel maneuverability is limited.

By staying as close as feasible to the starboard side of the channel, a vessel helps facilitate the safe passage of other vessels, particularly those that are following the same channel. This configuration allows for better visibility and navigational safety, as vessels can anticipate the positions and movements of others.

In a narrow channel, the expectation is that vessels will follow this rule to maintain order and safety in navigation. The incorrect choices present various misunderstandings of proper channel navigation. Some suggest improper positioning strategies that could lead to confusion or hazardous situations for all vessels operating within the narrowed confines of the channel. Overall, understanding and adhering to Rule 9 is vital for all mariners to promote safe and efficient navigation in congested waterways.
