When can the stand-on vessel take action to avoid collision?

1. At any time you feel it is appropriate

2. Only when you have reached extremis

3. When you determine that your present course will cross ahead of the other vessel

4. When it becomes apparent that the give-way vessel is not taking appropriate action

The correct answer is: When it becomes apparent that the give-way vessel is not taking appropriate action

The stand-on vessel can take action to avoid a collision when it becomes apparent that the give-way vessel is not taking appropriate action. This is based on the principles of navigation and the responsibilities of vessels under the International Regulations for Preventing Collisions at Sea (COLREGs). In situations where the stand-on vessel has the right of way, it is expected to maintain its course and speed. However, if there is a clear indication that the give-way vessel is not maneuvering correctly to avoid a collision, the stand-on vessel has the responsibility to take evasive action to ensure safety. This is crucial because the primary objective is to prevent a collision, and maintaining a course in the face of impending danger could lead to an accident. Understanding this aspect emphasizes the importance of vigilance and the ability to navigate safely even when you have the right of way, reinforcing that safety takes precedence over adherence to right-of-way rules in certain situations.
