How should a vessel respond to a Pan-pan call?

When a vessel receives a Pan-pan call, it indicates a situation that is urgent but not life-threatening. The correct response is to proceed with caution and assist if able. This means that the vessel should acknowledge the call and monitor the situation closely. The goal is to provide assistance to those in need, while ensuring the safety of your own vessel and crew.

Responding in this manner allows for a coordinated effort in emergencies. It may involve offering to assist the distressed vessel or providing information to authorities if necessary. Since Pan-pan calls imply urgency, it is important to maintain a lookout for other vessels and be prepared to take action if the situation escalates.

In contrast, options that suggest ignoring the call, changing course immediately, or sending a distress signal do not align with the protocols for handling a Pan-pan situation, as these do not adequately address the urgency or suggest readiness to assist. Thus, proceeding with caution and offering help where possible is the most responsible and effective response.
