How should a vessel navigate a narrow channel?

Navigating a narrow channel requires adherence to specific maritime rules to ensure safety and avoid collisions. The most appropriate approach is to remain as close to the outer limit on the starboard side as is safe. This aligns with the international regulations, specifically Rule 9 of the COLREGs, which emphasizes the need for vessels to navigate with caution in restricted visibility and narrow channels.

By staying close to the starboard side, a vessel facilitates safe passage for both itself and other vessels that may be following the recommended navigation patterns, as vessels are generally expected to keep to the right side of the channel. This not only helps maintain order and predictability within the channel but also enhances visibility, allowing for better maneuverability and communication with other vessels.

Furthermore, keeping to the starboard side minimizes the risk of collision when vessels are navigating in opposite directions. It also ensures that any assistive navigation aids, such as buoys and markers, which are typically positioned on the starboard side, can be observed and utilized effectively.

The other options do not adhere to these principles, as staying solely close to the left side or the center can lead to dangerous situations where vessels might not be able to avoid collisions or maintain proper navigation. Thus, maintaining proximity to the starboard
