GC B149 — SAR · MMSI 247473800

GC B149 has not broadcast an AIS position for 63 days. The most recent broadcast placed it in the Mediterranean Sea, on 7 Sep 2026, 15:37 UTC. It was sailing from SIRACUSA to SIRACUSA. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

GC B149 broadcasts MMSI 247473800. 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.

GC B149 is classified as a sar vessel registered under the IT flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full sar fleet at /vessel-type/tug-pilot-vessel and full IT flag list at /flag/it.

MarineRadar shows the latest AIS broadcast from GC B149 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 sar, GC B149 sits in the same design class as the other sars listed in the Similar Vessels section of the vessel page, or in the full sar directory at /vessel-type/tug-pilot-vessel.
