How should a vessel navigate a narrow channel?

When navigating a narrow channel, the correct approach is to remain as close to the outer limit on the starboard side as is safe. This is in line with the principles outlined in the COLREGs regarding navigation in confined waters. By keeping near the starboard side, a vessel ensures that it is compliant with the general rule of staying to the right, which helps to avoid collisions, particularly with other vessels that may be operating in the same channel.

Maintaining position close to the outer limit on the starboard side also allows for easier navigation and enhances visibility for both the vessel and others in the channel. This is especially critical in narrow channels where space is limited and the potential for encounters with other vessels is increased. Additionally, it aligns with the rule that vessels nearing a narrow channel should exhibit awareness of their surroundings and be prepared to yield to larger vessels that may have a deeper draft.

Navigating in the center of the channel regardless of circumstances disregards traffic and navigation guidelines, while keeping to the left side or close to the port side may lead to unsafe encounters with other vessels, including those that might be following the proper navigation rules for a narrow channel. Thus, close adherence to the starboard side is vital for safe passage and the prevention of collisions
