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 29, 2026, 05:50 UTC | Draught change Reported draught went from 18.9 m to 10.3 m while in port at Los Angeles. Voydar infers the ship probably discharged cargo. Method seadar.behaviour.draught_change v1 | High (75%) |

Derived from AIS positions of feeds whose terms allow display on Voydar. Coverage is terrestrial: gaps are reported only where our receivers kept hearing other ships. Detections below medium confidence are not shown.
