Live positions for merchant ships, ferries and yachts broadcasting AIS.
The shipping equivalent of a flight tracker, built on coastal AIS receivers and satellite feeds, with vessel details, photographs, port calls and expected arrival times. It answers questions nobody else does — where the ferry actually is, whether a container ship has cleared a canal, what that vessel on the horizon is. Coastal coverage is dense; mid-ocean depends on satellite data.
Questions
A genuinely usable free tier with paid plans for volume or team features. Free positions can lag by minutes and satellite coverage, voyage history and route forecasts are all paid features.
Yes. MarineTraffic sends your input to its own servers to process it. That is fine for public material; for anything containing personal data, use one of the on-device tools instead.
