Question 1

Where is ROYAL TERN right now?

Accepted Answer

ROYAL TERN has not broadcast an AIS position for 12 days. The most recent broadcast placed it in the North Pacific Ocean, on 28 Aug 2026, 01:13 UTC. It was sailing from BELLINGHAM to BELLINGHAM. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

Question 2

What are the identifiers for ROYAL TERN?

Accepted Answer

ROYAL TERN broadcasts MMSI 367147690, with call sign WDD4659. The MMSI is the radio identifier used by AIS; the IMO number stays with the ship for life and does not change with re-flagging or sale.

Question 3

What type of ship is ROYAL TERN?

Accepted Answer

ROYAL TERN is classified as a anti-pollution vessel registered under the US flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder and full US flag list at /flag/us.
