What should a vessel do to avoid impeding the passage of a vessel constrained by her draught?

A vessel should avoid impeding the navigation of a vessel constrained by her draught because such vessels are limited in their ability to maneuver due to their deep draft. This principle is rooted in the COLREGs, particularly Rule 18, which outlines the responsibilities of vessels when they are in the vicinity of others. A vessel that is constrained by her draught needs to navigate more carefully, particularly in shallow waters, and any actions that hinder this could lead to dangerous situations.

By avoiding impeding the navigation, the vessel ensures that it does not interfere with the constrained vessel’s ability to navigate safely. This is a fundamental aspect of maintaining safe and effective maritime traffic, as well as demonstrating a courteous approach to navigation among vessels of varying capabilities.

Other options may suggest actions that could unintentionally create hazards. For instance, speeding up and passing quickly may increase risk by not allowing sufficient time for safe passage. Changing course frequently could confuse the other vessel and potentially lead to collisions. Waiting for the vessel to pass, while potentially safe, may not always be practical or necessary, depending on the situation. Therefore, the emphasis on avoiding any action that would impede navigation is paramount in ensuring safety at sea.
