In navigation, which term identifies a vessel that is at a disadvantage when approaching another?

The term that identifies a vessel at a disadvantage when approaching another is the "give way vessel." In navigational rules, each vessel has specific responsibilities regarding right of way to ensure safe passage. The give way vessel is the one that must take action to avoid a collision by yielding to the other vessel. This situation often arises when two vessels are on a possible collision course, and the give way vessel must maneuver to allow the stand-on vessel to maintain its course and speed. This ensures the safety of both vessels, as the give way vessel is responsible for avoiding a potential accident.

In contrast, the stand-on vessel is the one that has the right of way and should maintain its course unless it becomes apparent that a collision cannot be avoided. Other terms, such as port-side vessel and sailing vessel, do not relate specifically to the right of way situation, making them less relevant in this context. Understanding the roles of these vessels is crucial for navigating safely and effectively on the water.
