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 Helena G is today. Her last recorded passage was 21 days before the archive ends, and that gap is about the record, not necessarily about the ship.

FreighterLog is the record, not the map. For where Helena G 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 Helena G 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. Helena G feed · all chokepoints
