(Pronounced pahn-pahn.) Use a “Pan-Pan” signal when a person’s or boat’s safety is threatened, but the situation’s not serious enough for a MAYDAY call. In other words, the boat’s in trouble, but it’s not in immediate danger of sinking. For example, use this signal when your boat’s engine is disabled, and you’re drifting near a rocky shore. Maybe the boat has a slow leak, is hung up in fishing gear, or is lost in fog. Or, if the boat’s steering system is broken, and you can’t control the boat, a “Pan-Pan” signal is appropriate.
