GL54 — Dredger · MMSI 338025000

GL54 has not broadcast an AIS position for 9 days. The most recent broadcast placed it in the North Atlantic Ocean, on 28 Oct 2026, 05:19 UTC. It was sailing from NEW YORK to BRUNSWICK ANCH. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

GL54 broadcasts MMSI 338025000, with call sign WDH5375. 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.

GL54 is classified as a dredger vessel registered under the US flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full dredger fleet at /vessel-type/military-special and full US flag list at /flag/us.

MarineRadar shows the latest AIS broadcast from GL54 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 dredger, GL54 sits in the same design class as the other dredgers listed in the Similar Vessels section of the vessel page, or in the full dredger directory at /vessel-type/military-special.
