Rule 18 outlines responsibilities between which of the following?

Rule 18 of the COLREGs addresses the responsibilities of vessels in relation to one another to ensure safe navigation and prevent collisions. It specifically applies to all vessels, regardless of their type or purpose. This includes power-driven vessels, sailing vessels, fishing vessels, and others, setting out who has the right of way in various circumstances.

The rule delineates various situations involving different types of vessels and describes which vessels must take action to avoid collisions. By stating that this rule applies to all vessels, it highlights the importance of mutual understanding and adherence to navigational rules across the entire maritime community. This broad applicability is crucial for the safe operation of vessels in crowded or complex marine environments, reinforcing that every vessel should understand its responsibilities towards others. Such an understanding aids in preventing misunderstandings and collisions at sea, which is the primary goal of the COLREGs.
