EnglishWhat Is MarineTraffic and What Information Does It Provide?
Updated
MarineTraffic is a global ship tracking and maritime intelligence platform built on AIS (Automatic Identification System) data. It shows near real-time vessel positions on a live ships map, lets you search a database of more than 550,000 active and decommissioned vessels, and provides vessel details, photos, and port locations. It is useful if you want to see where a specific ship is, monitor activity around a port, or look up basic information about a vessel. It is not a source of official navigational or legal records, so treat positions as indicative rather than authoritative.
What MarineTraffic actually does
The platform collects AIS signals that ships broadcast and turns them into a map-based view of global shipping traffic.
- Live ships map — near real-time positions of vessels around the world, plotted geographically.
- Vessel search — look up individual ships by name or other identifiers across a database of over 550,000 active and decommissioned vessels.
- Vessel details — information tied to a specific ship, plus ship photos where available.
- Port and ship locations — find where ports and vessels are using the map.
Information you can get
| What you want to know | Where it comes from |
|---|---|
| Where a ship is right now (approximately) | Live ships map, based on AIS |
| Whether a specific vessel exists in the database | Vessel search |
| Details about a vessel | Vessel detail view |
| What a vessel looks like | Ship photos |
| Where a port is and what's around it | Port and ship locations on the map |
How to use it
- Open the live map to get a global overview of vessel positions.
- Search for a vessel by name if you have a specific ship in mind — this queries the ships database.
- Open the vessel's page to see its details and any available photos.
- Zoom into a port or region on the map to see which vessels are nearby.
Expected result: you locate a vessel or port and read the information associated with it. The main limitation is coverage — AIS depends on ships transmitting and on receivers picking up the signal, so gaps and delays are normal.
When it's the right tool
Use MarineTraffic when you need a quick, map-based view of ship positions or basic vessel lookups. If you need official documentation, regulatory records, or guaranteed accuracy for operational decisions, this is not the right source — it is an intelligence and tracking view, not an authority.
