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.

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.
| When | What we observed | Confidence |
|---|---|---|
| Sep 24, 2026, 13:20 UTC | Draught change Reported draught went from 8.7 m to 6.6 m while in port at Kilpilahti (Skoldvik). Voydar infers the ship probably discharged cargo. Method seadar.behaviour.draught_change v1 | High (75%) |
