S.LEADER — Tanker - Hazard C (Minor) · IMO 9544853

S.LEADER has not broadcast an AIS position for 184 days. The most recent broadcast placed it in the Sea of Japan, on 6 May 2026, 04:12 UTC. It was sailing from YEOSU to ZHANGJIAGANG. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

S.LEADER broadcasts MMSI 566404000 and is registered as IMO 9544853. 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.LEADER is classified as a tanker - hazard c (minor) vessel registered under the SG flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full tanker - hazard c (minor) fleet at /vessel-type/tanker and full SG flag list at /flag/sg.

MarineRadar shows the latest AIS broadcast from S.LEADER 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 tanker - hazard c (minor), S.LEADER sits in the same design class as the other tanker - hazard c (minor)s listed in the Similar Vessels section of the vessel page, or in the full tanker - hazard c (minor) directory at /vessel-type/tanker.
