PILOT VESSEL ALERT — Pilot Vessel · MMSI 503022150

PILOT VESSEL ALERT has not broadcast an AIS position for 7 days. The most recent broadcast placed it in the South Pacific Ocean, on 2 Nov 2026, 01:28 UTC. It was sailing from RISDON to HOBART. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

PILOT VESSEL ALERT broadcasts MMSI 503022150. 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.

PILOT VESSEL ALERT is classified as a pilot vessel vessel registered under the AU flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full pilot vessel fleet at /vessel-type/tug-pilot-vessel and full AU flag list at /flag/au.

MarineRadar shows the latest AIS broadcast from PILOT VESSEL ALERT above, with current position, course, speed, and navigation status. Tap "View on map" to centre the live tracker on the vessel and watch its movement update in real time. The same data is available offline-friendly in the iOS and Android apps.

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.

As a pilot vessel, PILOT VESSEL ALERT sits in the same design class as the other pilot vessels listed in the Similar Vessels section of the vessel page, or in the full pilot vessel directory at /vessel-type/tug-pilot-vessel.
