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 30, 2026, 20:05 UTC	Draught change Reported draught went from 6.9 m to 7.9 m after leaving Mosjoen. Voydar infers the ship probably loaded cargo. Method seadar.behaviour.draught_change v1	Medium (55%)
Sep 23, 2026, 13:36 UTC	Draught change Reported draught went from 8.5 m to 6.8 m after leaving Pernis. Voydar infers the ship probably discharged cargo. Method seadar.behaviour.draught_change v1	Medium (55%)
