Your voyage planning indicates you will arrive at a waypoint in longitude 149°16.3'W at 0947 ZT on 3 March 1988. How should this date be entered into an AMVER report?

Correct Answer: Option A — 031947Z

AMVER position reporting requires local times to be converted to UTC. For longitude 149°16.3'W (UTC-10 hours), local time 0947 on 3 March requires adding 10 hours, resulting in 1947 UTC on the same date, formatted as 031947Z.
