GLAUCUS — High-Speed Craft · MMSI 235118101

GLAUCUS has not broadcast an AIS position for 222 days. The most recent broadcast placed it in the North Sea, on 31 Mar 2026, 21:19 UTC. It was sailing from RAMSGATE to RAMSGATE. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

GLAUCUS broadcasts MMSI 235118101, with call sign DATAHUB. 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.

GLAUCUS is classified as a high-speed craft vessel registered under the GB flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full high-speed craft fleet at /vessel-type/high-speed-craft and full GB flag list at /flag/gb.

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 high-speed craft, GLAUCUS sits in the same design class as the other high-speed crafts listed in the Similar Vessels section of the vessel page, or in the full high-speed craft directory at /vessel-type/high-speed-craft.
