When overtaking another vessel in a narrow channel, if that vessel sounds five short and rapid blasts, it is indicating that it is unsure of your intentions or that it is in a situation of danger. In this context, the correct response is to initiate another signal once the circumstances have stabilized. This is key since it’s important to clarify your intentions to the other vessel in order to ensure safety during the overtaking maneuver.

Initiating a signal after the situation has stabilized helps to communicate that you are aware of the potential danger and are taking action to proceed cautiously. This proactive communication can also help other vessels around you understand that you intend to navigate in a way that is safe and courteous, thus preventing misunderstandings.

In narrow channels, where navigating safely is critical, it’s essential to ensure clarity in communication, particularly in response to distress signals, thereby reducing the risk of collision.
