Question 1

Where is YIHE08 right now?

Accepted Answer

YIHE08 has not broadcast an AIS position for 19 days. The most recent broadcast placed it in the East China Sea, on 21 Aug 2026, 05:47 UTC. It was sailing from YANGKOU to YANGKOU. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

Question 2

What are the identifiers for YIHE08?

Accepted Answer

YIHE08 broadcasts MMSI 413312920. 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.

Question 3

What type of ship is YIHE08?

Accepted Answer

YIHE08 is classified as a port tender vessel registered under the CN flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder and full CN flag list at /flag/cn.

Question 5

How often is YIHE08's position updated?

Accepted Answer

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.
