Question 1

Where is RYUO II right now?

Accepted Answer

RYUO II has not broadcast an AIS position for 96 days. The most recent broadcast placed it in the North Pacific Ocean, on 4 Jun 2026, 20:07 UTC. It was sailing from PRINCE RUPERT to PRINCE RUPERT. 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 RYUO II?

Accepted Answer

RYUO II broadcasts MMSI 316016225, with call sign RYUO II. 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 RYUO II?

Accepted Answer

RYUO II is classified as a fishing vessel registered under the CA flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full fishing fleet at /vessel-type/fishing and full CA flag list at /flag/ca.

Accepted Answer
