SIRCHRISTOPHER — Cargo · MMSI 548529500

SIRCHRISTOPHER has not broadcast an AIS position for 4 days. The most recent broadcast placed it in the North Pacific Ocean, on 3 Nov 2026, 14:29 UTC. It was sailing from CARRASCAL to CEBU. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

SIRCHRISTOPHER broadcasts MMSI 548529500, with call sign DUH3165. 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.

SIRCHRISTOPHER is classified as a cargo vessel registered under the PH flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full cargo fleet at /vessel-type/cargo and full PH flag list at /flag/ph.

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 cargo, SIRCHRISTOPHER sits in the same design class as the other cargos listed in the Similar Vessels section of the vessel page, or in the full cargo directory at /vessel-type/cargo.
