When a sailing vessel is proceeding along a narrow channel, which vessels should not impede his passage?

In the context of navigation, when a sailing vessel is proceeding along a narrow channel, it is especially important to maintain safe and unobstructed passage for vessels that are constrained by their means of navigation. Power-driven vessels are generally expected to give way to sailing vessels, especially in confined waters, as sailing vessels may not have the same maneuverability due to their reliance on wind and the complexities of sailing.

Obstructing or impeding the passage of a sailing vessel in a narrow channel can lead to dangerous situations, as it may limit the options for the sailing vessel in terms of tacking or avoiding collisions. This commitment to ensuring that all other vessels, particularly those with power, do not impede the sailing vessel is rooted in the principles of safe navigation outlined in the COLREGs.

The rule emphasizes that all vessels—whether sailing, powered, or otherwise—should be cognizant of the rights of navigation of those vessels that may be more limited in their ability to maneuver. This is especially relevant in narrow channels where the operational space is restricted. Therefore, the correct assertion is that all other vessels, particularly powered ones, should ensure that they do not interfere with the safe passage of a sailing vessel navigating through such waters.
