VANGUARD — Passenger · MMSI 525007193

VANGUARD has not broadcast an AIS position for 19 days. The most recent broadcast placed it in the Java Sea, on 21 Oct 2026, 21:27 UTC. It was sailing from BANJARMASIN to TABONEO ANCH. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

VANGUARD broadcasts MMSI 525007193. 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.

VANGUARD is classified as a passenger vessel registered under the ID flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full passenger fleet at /vessel-type/passenger and full ID flag list at /flag/id.

MarineRadar shows the latest AIS broadcast from VANGUARD 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 passenger, VANGUARD sits in the same design class as the other passengers listed in the Similar Vessels section of the vessel page, or in the full passenger directory at /vessel-type/passenger.
