What must vessels do if they are equipped with a radio and hear a distress call?

When vessels equipped with a radio hear a distress call, they are required to maintain a listening watch and respond if possible. This requirement stems from the principles established in the International Convention for the Safety of Life at Sea (SOLAS) and the guidelines set forth in the COLREGs regarding communications and responses in emergency situations.

Listening for distress calls ensures that vessels can assist in emergencies by providing timely help or information. If a ship is in a position to offer assistance or has relevant information regarding the distress situation, responding is critical for the safety of those in peril. Ignoring such calls could result in unnecessary loss of life or further escalation of the emergency.

In summary, the obligation to listen and potentially respond emphasizes the maritime community's commitment to safety and mutual support on the water, demonstrating the importance of communication in distress scenarios.
