Frequently Asked Questions

Where is CHRISSY right now?+
CHRISSY has not broadcast an AIS position for 3 days. The most recent broadcast placed it in the North Pacific Ocean, on 5 Sep 2026, 08:56 UTC. It was sailing from VANCOUVER to PORTLAND OR. 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 CHRISSY?+
CHRISSY broadcasts MMSI 368280980, with call sign WDN4436. 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 CHRISSY?+
CHRISSY is classified as a tug vessel registered under the US flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full tug fleet at /vessel-type/tug-pilot-vessel and full US flag list at /flag/us.

How often is CHRISSY'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.
