OSTRIA — Passenger · MMSI 237015600

OSTRIA has not broadcast an AIS position for 128 days. The most recent broadcast placed it in the Mediterranean Sea, on 4 Jul 2026, 08:06 UTC. It was sailing from AGIOS NIKOLAOS to AGIOS NIKOLAOS. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

OSTRIA broadcasts MMSI 237015600. 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.

OSTRIA is classified as a passenger vessel registered under the GR 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 GR flag list at /flag/gr.

MarineRadar shows the latest AIS broadcast from OSTRIA 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, OSTRIA 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.
