HARBOUR PROGRESS — Tanker · IMO 9572745

HARBOUR PROGRESS has not broadcast an AIS position for 4 days. The most recent broadcast placed it in the Caribbean Sea, on 2 Nov 2026, 18:00 UTC. It was sailing from POINT LISAS to THREE RIVERS. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

HARBOUR PROGRESS broadcasts MMSI 255804290 and is registered as IMO 9572745, with call sign CQNY. 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.

HARBOUR PROGRESS is classified as a tanker vessel registered under the PT flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full tanker fleet at /vessel-type/tanker and full PT flag list at /flag/pt.

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.

HARBOUR PROGRESS is classed by AMERICAN BUREAU OF SHIPPING, the classification society responsible for inspecting the vessel against safety, structural and operational rules. As a tanker, HARBOUR PROGRESS sits in the same design class as the other tankers listed in the Similar Vessels section of the vessel page, or in the full tanker directory at /vessel-type/tanker.
