Which of the following can a coast station do to manage messages for ships?

The best approach for a coast station in managing messages for ships involves transmitting lists of call signs to indicate which vessels have messages waiting. This method facilitates communication and ensures that vessels are aware of their specific messages without overwhelming them or cluttering the communication frequency. By broadcasting lists of call signs, the coast station can efficiently inform ships of pending communications, allowing them to take appropriate action when it suits their operational needs.

Handling communications this way is beneficial as it improves the efficiency of message delivery and ensures vessels are not flooded with simultaneous messages, which could lead to confusion or miscommunication. It supports a structured approach to manage traffic and enhances the overall safety and organization of maritime communications.

While other options may present potential actions, they do not align with best practices for effective communication management in a nautical context.
