What is the definition of a "distress alert" according to COLREGs?

A "distress alert" is defined as a signal that indicates a vessel is in distress and requires assistance. This aligns with the International Regulations for Preventing Collisions at Sea (COLREGs), which provide guidance on maritime safety and communication. When a vessel sends a distress alert, it is indicating an emergency situation, such as being at risk of sinking, grounding, or experiencing other critical issues that compromise its safety.

This definition emphasizes the urgency and seriousness of the situation, allowing other vessels and rescue services to respond appropriately and swiftly to help those in need. The clarity of such signals is crucial in maritime operations to ensure quick identification of emergencies, enabling effective search and rescue operations.

The other options do not pertain to distress alerts, as they refer to different scenarios that do not involve an immediate need for assistance. For instance, bad weather warnings and notifications of routine movements are part of navigation and safety communications but are not classified as distress signals. Similarly, a signal indicating that a vessel is anchored does not suggest any urgent requirement for help, which further clarifies the specific nature of a distress alert.
