P J MARINE PATROL — Law Enforce · MMSI 338466234

P J MARINE PATROL has not broadcast an AIS position for 3 days. The most recent broadcast placed it in the North Atlantic Ocean, on 5 Nov 2026, 16:41 UTC. It was sailing from MOUNT SINAI to PORT JEFFERSON. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

P J MARINE PATROL broadcasts MMSI 338466234, with call sign H M P J. 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.

P J MARINE PATROL is classified as a law enforce vessel registered under the US flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full law enforce fleet at /vessel-type/military-special and full US flag list at /flag/us.
