Frequently Asked Questions

Where is ALCYON right now?+
ALCYON has not broadcast an AIS position for 38 days. The most recent broadcast placed it in the North Sea, on 2 Aug 2026, 03:58 UTC. It was sailing from LEEUWARDEN to FRANEKER. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

What type of ship is ALCYON?+
ALCYON is a maritime vessel registered under the NL flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder and full NL flag list at /flag/nl.

How often is ALCYON's position updated?+
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.
