MISTER MARCO — Port Tender · MMSI 367587070

MISTER MARCO has not broadcast an AIS position for 6 days. The most recent broadcast placed it in the North Atlantic Ocean, on 2 Nov 2026, 17:02 UTC. It was sailing from JUDITH POINT to JUDITH POINT. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

MISTER MARCO broadcasts MMSI 367587070, with call sign WDP3966. 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.

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

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 port tender, MISTER MARCO sits in the same design class as the other port tenders listed in the Similar Vessels section of the vessel page.
