What does Rule 18 of the Navigation Rules cover?

Rule 18 of the Navigation Rules specifically addresses the responsibilities between vessels in various situations, particularly concerning their conduct when encountering one another. This rule outlines the actions that different types of vessels must take when they are in proximity to each other to promote safe navigation and prevent collisions.

For example, Rule 18 specifies the 'give way' responsibilities, indicating which vessel must take measures to avoid collisions depending on their type and the situation at hand. This includes categories like power-driven vessels, sailing vessels, vessels engaged in fishing, and more.

The other options pertain to different aspects of navigation; for instance, signaling in fog is covered under different rules specifically addressing sound signaling and visibility, while docking procedures and speed limits in congested areas are dealt with separately as well. Understanding the scope of Rule 18 is essential for mariners to ensure that they maintain proper conduct and safety on the water when navigating with other vessels.
