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.
Predicted arrival
Voydar estimates arrival at Rotterdam around Oct 5, 2026, 14:35 UTC, most likely between Oct 1, 2026, 22:14 UTC and Oct 14, 2026, 01:14 UTC. Based on 42 past transits between NLBOT and Rotterdam seen in our port calls. The crew-reported ETA is Oct 1, 2026, 12:30 UTC.
