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.

Draught change

Reported draught went from 16.5 m to 9 m after leaving Durban. Voydar infers the ship probably discharged cargo.
