What situation is specifically addressed by Rule 9?

Rule 9 of the Navigation Rules specifically addresses vessels navigating in narrow channels or fairways. This rule provides guidelines for the proper conduct of vessels when they are operating in these constrained environments, ensuring that all mariners are aware of their responsibilities in maintaining safety and avoiding collisions.

The rule emphasizes that vessels must keep to the starboard side of the channel and outlines who has the right of way, typically favoring larger vessels that are constrained by their draft. This helps to organize traffic and prevent mishaps in narrow waters, where maneuverability is limited. Understanding Rule 9 is crucial for safe navigation in these areas, as it plays a significant role in guiding vessel conduct and ensuring safe passage through confined waterways.
