What action should you take if your vessel is being overtaken by another vessel?

When a vessel is being overtaken, the appropriate action is to maintain course and speed. According to the Rules of the Road, a vessel that is being overtaken has the right to continue its navigation as long as it is safe and no risk of collision is present. The overtaking vessel is required to keep clear of the vessel it is overtaking. By maintaining steady course and speed, the overtaken vessel allows the overtaking vessel to safely pass without making sudden maneuvers that could lead to confusion or an increased risk of collision.

Choosing to alter course or reduce speed without a clear need could create uncertainty for the overtaking vessel, increasing the potential for collision. Additionally, sounding a short blast does not apply in this situation, as it is typically used for signaling intentions rather than addressing overtaking scenarios. Thus, maintaining course and speed is the safest and most appropriate action when being overtaken.
