Miss Mary Ann was observed on the lakes in the AIS sample used to build the roster, but crossed none of the 7 monitored chokepoints between January 2024 and December 2025.

This is an archive, not a tracker. The passage record runs January 2024 to December 2025 and ends at 31 Dec 2025. The public AIS archive arrives in quarterly batches and currently runs nine months behind. Nothing on this page tells you where Miss Mary Ann is today.

FreighterLog is the record, not the map. For where Miss Mary Ann is right now, see BoatNerd's live AIS map, which runs on their own receivers on the lakes, or VesselFinder.

Follow by RSS. Every crossing Miss Mary Ann makes goes into a feed of her own, added when the next batch of the public AIS archive is processed. It is a file on this domain: no account, no email address, and nothing that reports back. Miss Mary Ann feed · all chokepoints
