Frequently Asked Questions

Where is IMUA right now?+
IMUA has not broadcast an AIS position for 7 days. The most recent broadcast placed it in the North Pacific Ocean, on 2 Sep 2026, 00:44 UTC. It was sailing from HONOLULU to HONOLULU . Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.
What are the identifiers for IMUA?+

What type of ship is IMUA?+
IMUA is a maritime 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.
How can I see the live position of IMUA?+

How often is IMUA's position updated?+
AIS transponders broadcast position every 2 seconds when underway at high speed and up to every 3 minutes at anchor. The position you see refreshes whenever the ship is in range of a coastal AIS receiver or a satellite pass — typically seconds in coastal waters and minutes offshore.
What class is IMUA?+
The vessel's design class is inferred from its dimensions, gross tonnage and dead weight, all of which are listed in the Identity and Specifications panels on the vessel page.
