Which action should a vessel take when being overtaken by another vessel?

Answer: B — Maintain course and speed

When a vessel is being overtaken by another vessel, the appropriate action is to maintain course and speed. This is outlined in the COLREGs, specifically under Rule 13, which governs overtaking situations. The overtaken vessel should hold its steady course and speed to allow the overtaking vessel to pass safely and without confusion. Maintaining course and speed provides clarity in maneuvering, as it ensures that the overtaking vessel can predict the movements of the overtaken vessel, thus reducing the risk of collision. Abruptly changing course or speed may result in unexpected situations that could lead to dangerous encounters, as the overtaking vessel could misinterpret these actions. Additionally, signaling distress is not relevant in this context, and alerting other vessels in the area may not be necessary when the situation is being managed properly by maintaining a steady course and speed. This adherence to the rules of navigation is essential for safe operation at sea.
