Port calls

Two kinds of evidence, kept apart: calls Seadar detected from the ship's AIS positions, and arrivals and departures published by port authorities and customs records.

Detected from AIS AIS-detected

Port	Arrived	Departed	Time in port
Tampa USTPA	Sep 25, 2026, 02:54 UTC	Sep 26, 2026, 02:39 UTC	23 h 45 min
Port Manatee USPME	Sep 24, 2026, 00:26 UTC	Sep 25, 2026, 00:24 UTC	23 h 58 min

Detected by Seadar when the ship's AIS positions stayed slow inside a harbour area. Calls shorter than 30 minutes are not shown. Depends on AIS reception; detection started on June 8, 2026.

Behaviour at sea Seadar-derived

Patterns Seadar 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 24, 2026, 12:56 UTC	Draught change Reported draught went from 11.6 m to 8.5 m while in port at Port Manatee. Seadar infers the ship probably discharged cargo. Method seadar.behaviour.draught_change v1	High (75%)
