You are a vessel aground, what additional light signal shall be lighted to distinguish you from an anchored vessel?
- A.
3 red lights in vertical
- B.
2 white lights in vertical
- C.
2 red lights in vertical
- D.
2 white lights
Correct Answer
A. 3 red lights in verticalExplanation
When a vessel is aground, it means that it is stuck or stranded on the ground or a submerged object. In this situation, to distinguish the vessel from an anchored vessel, it is required to display additional light signals. According to the International Regulations for Preventing Collisions at Sea (COLREGs), a vessel aground should display three red lights in a vertical line. This signal helps other vessels to recognize the vessel's predicament and take appropriate action to avoid a collision. The other options, such as two white lights in vertical or two red lights, do not specifically indicate a vessel aground and may cause confusion for other vessels.Rate this question:
