GRINDA — Fishing · IMO 8921145

GRINDA has not broadcast an AIS position for 25 days. The most recent broadcast placed it in the Sea of Japan, on 15 Oct 2026, 02:35 UTC. It was sailing from VLADIVOSTOK to OKHOTSK. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

GRINDA broadcasts MMSI 273216740 and is registered as IMO 8921145, with call sign UBAU3. 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.

GRINDA is classified as a fishing vessel registered under the RU 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 RU flag list at /flag/ru.

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 fishing, GRINDA sits in the same design class as the other fishings listed in the Similar Vessels section of the vessel page, or in the full fishing directory at /vessel-type/fishing. GRINDA has a gross tonnage of 742 GT.
