Which rule establishes the hierarchy of vessels?

Rule 18 of the International Regulations for Preventing Collisions at Sea (COLREGs) specifies the responsibilities of vessels in various situations, establishing a hierarchy to navigate safely and effectively. This rule identifies which vessels must take action to avoid collision and gives priority to certain types of vessels over others.

For example, Rule 18 states that vessels engaged in fishing shall keep out of the way of vessels that are not under command, vessels that are restricted in their ability to maneuver, and vessels engaged in towing or pushing. This prioritization helps to prevent accidents on the water by clearly defining which vessels have the right of way in specific scenarios.

Understanding Rule 18 is essential for mariners, as it outlines the expected conduct of vessels in different operational states and ensures that maritime traffic can coexist safely on the waterways. It’s important for vessel operators to be familiar with this hierarchy to make informed decisions while navigating, especially in crowded or confined waters.
