What should a vessel do if it loses communication with shore stations?

When a vessel loses communication with shore stations, the appropriate action is to periodically attempt to re-establish contact. This proactive approach is vital for safety, as communication ensures that the vessel can receive navigational updates, weather reports, and emergency information. It also allows the vessel to inform shore stations or relay them of its status and intentions when communication is regained.

Regularly trying to re-establish contact demonstrates a commitment to maintaining safe operations and ensures that the vessel can act on any important information it might miss due to the communication breakdown. This approach aligns with best practices in maritime operations, emphasizing the importance of maintaining situational awareness and safety.

The other options may not effectively address the situation. While notifying other vessels sounds prudent, it could create unnecessary alarm if the situation is not critical. Reducing speed and anchoring may limit the vessel's maneuverability and could impede rescue or assistance if needed. Changing course to return to port might not be feasible or necessary, especially if the vessel is in a safe operational area and can continue its journey while trying to regain communication.
