Which statement is true regarding the process of Distress alerting under GMDSS?

The statement that alerts must indicate the vessel's position and assistance needed is accurate because effective distress alerting in the Global Maritime Distress and Safety System (GMDSS) is critical for ensuring that help can be directed to the precise location of a distressed vessel. When a vessel sends a distress alert, it is essential that this communication includes clear information about the vessel's current position, as well as the specific nature of the assistance required, whether it's searching for survivors, medical emergencies, or other forms of help. This information is vital for nearby vessels, coast guard services, and other relevant authorities to respond quickly and effectively.

Providing precise location data can significantly enhance the chances of a rapid rescue operation, allowing responders to calculate the best route and mobilize the necessary resources. This practice aligns with the overarching goal of the GMDSS, which is to improve the safety of life at sea through effective and prompt communication of distress situations.
