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 27, 2026, 02:20 UTC | Draught change Reported draught went from 8 m to 9.8 m while in port at Portland. Voydar infers the ship probably loaded cargo. Method seadar.behaviour.draught_change v1 | Medium (65%) |
| Sep 25, 2026, 22:15 UTC | Draught change Reported draught went from 10.2 m to 8 m while in port at Portland. Voydar infers the ship probably discharged cargo. Method seadar.behaviour.draught_change v1 | High (75%) |
