What does Rule 10j state about vessels less than 20m or sailing vessels?

Rule 10j of the COLREGs specifically addresses the obligations of vessels less than 20 meters in length and sailing vessels within traffic separation schemes. It establishes that these smaller vessels must not impede the safe passage of a power-driven vessel that can safely navigate within a deep-water route. This rule emphasizes the importance of allowing larger vessels, which often have limited maneuverability and greater navigation requirements, to operate safely in their designated lanes.

By identifying that smaller vessels must ensure they do not obstruct the movement of larger, power-driven vessels, Rule 10j underlines the responsibility all vessels have to promote safety on the water, particularly in busy navigational routes. This rule is crucial for preventing collisions and ensuring that all vessels can transit safely without risking hazards or unnecessary maneuvers.

While it might seem logical to consider other options, such as yielding to larger vessels or being prohibited in traffic lanes, those statements do not capture the essence of Rule 10j. The focus is not merely on yielding or prohibitions, but rather on the specific responsibility of smaller vessels to avoid causing inconvenience or danger to larger vessels traversing the traffic lanes safely.
