WANG NAI — Passenger · IMO 5420956

WANG NAI has not broadcast an AIS position for 5 days. The most recent broadcast placed it in the South China Sea, on 3 Nov 2026, 07:30 UTC. It was sailing from OSAKA to OSAKA. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

WANG NAI broadcasts MMSI 567002816 and is registered as IMO 5420956. 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.

WANG NAI is classified as a passenger vessel registered under the TH flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full passenger fleet at /vessel-type/passenger and full TH flag list at /flag/th.

MarineRadar shows the latest AIS broadcast from WANG NAI 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 passenger, WANG NAI sits in the same design class as the other passengers listed in the Similar Vessels section of the vessel page, or in the full passenger directory at /vessel-type/passenger.
