What is the purpose of a Distress call in the GMDSS system?

The purpose of a Distress call in the GMDSS (Global Maritime Distress and Safety System) is to alert authorities and nearby vessels of an emergency situation that requires immediate assistance. When a vessel sends out a Distress call, it communicates that there is a critical situation, such as an accident, fire, grounding, or any scenario where lives or property are in danger.

This call is a vital component of maritime safety as it prompts the closest ships and rescue authorities to respond quickly, helping to save lives and mitigate potential losses. GMDSS provides specific protocols for issuing Distress calls, ensuring clarity and urgency in the message being sent.

The other options pertain to communication scenarios that are important but do not represent emergency situations that necessitate immediate assistance. Regular communications, navigational hazards, or weather information have their own protocols and do not carry the same level of urgency or critical response requirement associated with a Distress call.
