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 4, 2026, 04:52 UTC | Draught change Reported draught went from 8.9 m to 9.8 m while in port at Lillo. Voydar infers the ship probably loaded cargo. Method seadar.behaviour.draught_change v1 | Medium (65%) |
| Sep 27, 2026, 11:22 UTC | Draught change Reported draught went from 5.7 m to 8.6 m while in port at Stader Sand. Voydar infers the ship probably loaded cargo. Method seadar.behaviour.draught_change v1 | High (75%) |
| Sep 23, 2026, 17:37 UTC | Draught change Reported draught went from 7.5 m to 4.7 m while in port at Amsterdam. Voydar infers the ship probably discharged cargo. Method seadar.behaviour.draught_change v1 | High (75%) |
