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 25, 2026, 20:42 UTC | Draught change Reported draught went from 5.8 m to 4.5 m after leaving Semarang. Voydar infers the ship probably discharged cargo. Method seadar.behaviour.draught_change v1 | Medium (55%) |
