Port calls

Two kinds of evidence, kept apart: calls Voydar detected from the ship's AIS positions, and arrivals and departures published by port authorities and customs records.

Detected from AIS AIS-detected

Port	Arrived	Departed	Time in port
Arcachon FRARC	Oct 4, 2026, 08:46 UTC	Oct 5, 2026, 01:14 UTC	16 h 28 min

Detected by Voydar when the ship's AIS positions stayed slow inside a harbour area. Calls shorter than 30 minutes are not shown. Depends on AIS reception; detection started on June 8, 2026.

Behaviour at sea Voydar-derived

Patterns Voydar derived from this ship's AIS broadcasts. They are inferences, not reports: each one shows how it was computed and how confident we are, and none of them says why a ship behaved this way.
