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 28, 2026, 13:16 UTC	Draught change Reported draught went from 8.3 m to 7.7 m after leaving Gdynia. Voydar infers the ship probably discharged cargo. Method seadar.behaviour.draught_change v1	Medium (55%)
Sep 27, 2026, 18:08 UTC	Draught change Reported draught went from 11.3 m to 8.3 m while in port at Gdynia. Voydar infers the ship probably discharged cargo. Method seadar.behaviour.draught_change v1	High (75%)
