MARCELINO BARBOSA — Unknown · MMSI 204209000

MARCELINO BARBOSA has not broadcast an AIS position for 171 days. The most recent broadcast placed it in the North Atlantic Ocean, on 21 May 2026, 16:13 UTC. It was sailing from POVOA DE VARZIM to LEIXOES. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

MARCELINO BARBOSA broadcasts MMSI 204209000, with call sign CUOV5. 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.

MARCELINO BARBOSA is classified as a unknown vessel registered under the PT flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder and full PT flag list at /flag/pt.

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.
