Which vessel is required to take immediate action to avoid collision according to navigation rules?

The requirement for a vessel to take immediate action to avoid collision is crucial for safely navigating busy waters. The give-way vessel is designated by navigation rules to yield to another vessel's right of way. This means that if two vessels are on a collision course, the give-way vessel must take immediate action to prevent a collision, which can include changing speed, direction, or both.

This obligation arises because the stand-on vessel is expected to maintain its course and speed, relying on the give-way vessel to take evasive action. The term "give-way vessel" specifically refers to the vessel that has the responsibility to avoid the other, underscoring the importance of proactive maneuvering to reduce the risk of accidents. By understanding this concept clearly, mariners can navigate more safely and prevent collisions, enhancing maritime safety overall.
