Your voyage planning indicates you will arrive at a waypoint in longitude 49°16.3'E at 0947 ZT on 3 March 1988. How should this date be entered into an AMVER report?

Correct Answer: Option A — 030647Z MAR

At longitude 49°16.3'E, the zone description is -3 hours. Converting local time (0947 on 3 March) to UTC requires subtracting 3 hours, resulting in 0647 UTC on 03 March. Formatted for AMVER, this reads 030647Z MAR.
