S J BOSS has not broadcast an AIS position for 43 days. The most recent broadcast placed it in the Persian Gulf, on 25 Sep 2026, 03:17 UTC. It was sailing from JEBEL ALI to KARACHI. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

S J BOSS broadcasts MMSI 620999523 and is registered as IMO 9168532, with call sign D6A3522. 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.

S J BOSS 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.
