HELENA — Passenger · MMSI 211514900

HELENA has not broadcast an AIS position for 27 days. The most recent broadcast placed it, on 10 Oct 2026, 14:56 UTC. It was sailing from KELHEIM to REGENSBURG. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

HELENA broadcasts MMSI 211514900, with call sign DC3639. 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.

HELENA is classified as a passenger vessel registered under the DE flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full passenger fleet at /vessel-type/passenger and full DE flag list at /flag/de.

MarineRadar shows the latest AIS broadcast from HELENA above, with current position, course, speed, and navigation status. Tap "View on map" to centre the live tracker on the vessel and watch its movement update in real time. The same data is available offline-friendly in the iOS and Android apps.

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 passenger, HELENA sits in the same design class as the other passengers listed in the Similar Vessels section of the vessel page, or in the full passenger directory at /vessel-type/passenger.
