SEA MASTER — Cargo · IMO 8601991

SEA MASTER has not broadcast an AIS position for 233 days. The most recent broadcast placed it in the Red Sea, on 21 Mar 2026, 03:40 UTC. It was sailing from SUEZ SOUTH ANCH to SUEZ SOUTH ANCH. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

SEA MASTER broadcasts MMSI 620056000 and is registered as IMO 8601991, with call sign D6A3468. 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.

SEA MASTER is classified as a cargo vessel registered under the KM 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 KM flag list at /flag/km.

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, SEA MASTER 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. SEA MASTER has a gross tonnage of 1,636 GT.
