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.

Oct 5, 2026, 19:47 UTC	Draught change Reported draught went from 11.8 m to 12.9 m while in port at Seattle. Voydar infers the ship probably loaded cargo. Method seadar.behaviour.draught_change v1	Medium (65%)
