HOS BLACK WATCH — Cargo · IMO 9647710

HOS BLACK WATCH has not broadcast an AIS position for 6 days. The most recent broadcast placed it in the Bering Sea, on 1 Nov 2026, 19:00 UTC. It was sailing from ADAK to DUTCH HARBOR. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

HOS BLACK WATCH broadcasts MMSI 367612330 and is registered as IMO 9647710, with call sign WDH3922. 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.

HOS BLACK WATCH is classified as a cargo vessel registered under the US 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 US flag list at /flag/us.
