What comprises a complete Distress message?

A complete Distress message is critical for effective communication during emergencies at sea. It must provide essential information that enables rescuers to understand the situation and respond appropriately. The key components involve identifying the vessel in distress and articulating the nature of the distress.

The correct answer includes the name of the vessel, call sign, and nature of distress. The name of the vessel allows rescuers to identify who is in need of assistance, while the call sign provides a standardized, recognizable identifier for communication purposes. Knowing the nature of the distress—whether it be sinking, fire, grounding, or other emergencies—helps search and rescue teams understand the urgency and the specific hazards they must prepare for.

In contrast, while the other options mention various elements that could assist in understanding the situation, they do not present a complete message sufficient for initiating a distress call. For instance, details such as weather conditions or crew size may be relevant but are not essential for the immediate needs of the distress situation. Thus, option C succinctly encapsulates the essential elements required for a complete distress message.
