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 |
|---|---|---|
| Oct 1, 2026, 17:38 UTC | Draught change Reported draught went from 5.6 m to 8.7 m while in port at Rozenburg. Voydar infers the ship probably loaded cargo. Method seadar.behaviour.draught_change v1 | High (75%) |
| Sep 28, 2026, 22:39 UTC | Draught change Reported draught went from 8.9 m to 5.6 m while in port at Lillo. Voydar infers the ship probably discharged cargo. Method seadar.behaviour.draught_change v1 | High (75%) |
