Frequently Asked Questions

Where is DUCHESS right now?+
DUCHESS has not broadcast an AIS position for 13 days. The most recent broadcast placed it in the Coral Sea, on 26 Aug 2026, 05:07 UTC. It was sailing from TANGALOOMA to HOPE ISLAND. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.
What are the identifiers for DUCHESS?+
DUCHESS broadcasts MMSI 503168040. 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.
What type of ship is DUCHESS?+
DUCHESS is classified as a pleasure craft vessel registered under the AU flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full pleasure craft fleet at /vessel-type/yacht and full AU flag list at /flag/au.

How often is DUCHESS'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.
