SLEIPNIR — Pilot Vessel · MMSI 251272110

SLEIPNIR has not broadcast an AIS position for 3 days. The most recent broadcast placed it in the North Atlantic Ocean, on 3 Nov 2026, 15:40 UTC. It was sailing from AKUREYRI to AKUREYRI. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

SLEIPNIR broadcasts MMSI 251272110. 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.

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

MarineRadar shows the latest AIS broadcast from SLEIPNIR 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 pilot vessel, SLEIPNIR sits in the same design class as the other pilot vessels listed in the Similar Vessels section of the vessel page, or in the full pilot vessel directory at /vessel-type/tug-pilot-vessel.
