MISS JOANNA — Reserved · MMSI 657275900

MISS JOANNA has not broadcast an AIS position for 8 days. The most recent broadcast placed it, on 30 Oct 2026, 16:03 UTC. It was sailing from BONNY to PORT HARCOURT. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

MISS JOANNA broadcasts MMSI 657275900. 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.

MISS JOANNA is a maritime vessel registered under the NG flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder and full NG flag list at /flag/ng.

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.

The vessel's design class is inferred from its dimensions, gross tonnage and dead weight, all of which are listed in the Identity and Specifications panels on the vessel page.
