SEA LEOPARD — Dive Vessel · MMSI 235023771

SEA LEOPARD has not broadcast an AIS position for 31 days. The most recent broadcast placed it in the North Sea, on 6 Oct 2026, 19:53 UTC. It was sailing from DOVER to DOVER. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

SEA LEOPARD broadcasts MMSI 235023771. 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 LEOPARD is classified as a dive vessel vessel registered under the GB flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full dive vessel fleet at /vessel-type/military-special and full GB flag list at /flag/gb.

MarineRadar shows the latest AIS broadcast from SEA LEOPARD above, with current position, course, speed, and navigation status. Tap "View on map" to centre the live tracker on the vessel and watch its movement update in real time. The same data is available offline-friendly in the iOS and Android apps.

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 dive vessel, SEA LEOPARD sits in the same design class as the other dive vessels listed in the Similar Vessels section of the vessel page, or in the full dive vessel directory at /vessel-type/military-special.
