Frequently Asked Questions

Where is POSEIDON right now?+
POSEIDON has not broadcast an AIS position for 6 days. The most recent broadcast placed it in the North Pacific Ocean, on 2 Sep 2026, 17:22 UTC. It was sailing from PUERTO ESCONDIDO to SAN DIEGO. 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 POSEIDON?+
POSEIDON broadcasts MMSI 367744660 and is registered as IMO 8981793, with call sign WDI9041. 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.
What type of ship is POSEIDON?+
POSEIDON is classified as a pleasure craft vessel registered under the US flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full pleasure craft fleet at /vessel-type/yacht and full US flag list at /flag/us.

How often is POSEIDON'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.
