A vessel of less than 20m in length is proceeding along a narrow channel. Who should not impede his passage?

For a vessel of less than 20 meters in length navigating along a narrow channel, it is essential that all vessels from either side do not impede its passage. This principle is grounded in the regulations set forth by the COLREGs, specifically Rule 9 concerning narrow channels. The guidance stipulates that vessels should take care to avoid impeding the safe transit of smaller vessels, particularly when those vessels are constrained by their draft or operational limitations.

The reasoning behind this rule is to enhance navigation safety and ensure that larger vessels do not obstruct smaller vessels that may be less maneuverable or slower. All vessels, regardless of their size, are required to maintain a safe distance and manage their actions to avoid interference, ensuring that the smaller vessel can navigate through the narrow channel without undue risk. This promotes safe maritime navigation for all vessels operating in constrained waters.
