Track line joining: Introduces a route through a series of positions — a cable route, a tow's track or a survey line.
Position (degrees and minutes): How warnings write positions: degrees, a hyphen, then minutes, with N/S and E/W — 49-40.8N 003-43.8W.
Inmarsat-C / SafetyNET: The satellite system that carries NAVAREA warnings to ships at sea, and the terminal number rescue centres give for reports.
CANCEL THIS MSG: The warning's own expiry: a line telling the reader when the message cancels itself.
