MarineTraffic – Live Ship Tracking Worldwide
Explore live vessel positions, ship information, ports and AIS-based maritime traffic around the world with MarineTraffic.
MarineTraffic Live Ship Map
Use the interactive map to explore reported vessel positions and maritime traffic around the world. Available positions depend on AIS coverage and the data shown by MarineTraffic.
What Is MarineTraffic?
MarineTraffic is an online maritime tracking service that displays vessel positions, ship information and port-related data based primarily on AIS and other maritime data sources.
Users can explore commercial ships, passenger vessels, tankers, ferries, pleasure craft and many other vessel types. Depending on the available data, ship profiles may include vessel identification, destination, speed, course, dimensions and voyage-related information.
MarineTraffic offers both free and paid services. Basic map and vessel information can be available without a subscription, while advanced tracking, satellite data and professional maritime tools may require a paid plan.

Explore Ships and Ports Worldwide
MarineTraffic combines vessel position reports with interactive map tools. Users can search for specific ships, inspect available vessel details and explore traffic around ports and coastal regions.
Public ship tracking is particularly useful for following cruise ships, cargo vessels, tankers and other commercial traffic. Position availability and update intervals can vary depending on receiving coverage and the underlying data source.
Comment fonctionne MarineTraffic?
MarineTraffic uses maritime data, especially AIS, to display reported vessel positions and ship information on interactive maps.
Vessel Identity
AIS can transmit identifiers such as MMSI, call sign and other vessel-related information.
Position
Reported latitude and longitude can be displayed on the live map when suitable AIS coverage is available.
Speed & Course
AIS messages can include Speed Over Ground and Course Over Ground for moving vessels.
Voyage Data
Depending on the ship, destination, ETA and other voyage-related details may also be transmitted.
Tracking Beyond Standard AIS
MarineTraffic can also display selected position reports from vessels that do not rely on a conventional AIS transponder, depending on the service and reporting method used.
Position information may be contributed through connected mobile devices, compatible tracking equipment or other supported reporting methods. Such reports should be understood separately from standard AIS transmissions.
MarineTraffic Ship Symbols and Vessel Types
Different colors and symbols help distinguish vessel categories on the map. The table below preserves the existing Ship-Tracker.org visual guide for moving and stopped vessels.
| Ship Type | On the Way | Stopped |

Why MarineTraffic Uses AIS
AIS is one of the most important data sources used for public vessel tracking because it allows ships to transmit identification and navigation-related information.
AIS can transmit information such as vessel identity, position, speed and course. Shore-based receiving stations can collect these signals near coastlines and ports, while satellite-based AIS can extend coverage into more remote ocean areas.
AIS was developed primarily as an aid to maritime navigation and situational awareness. Public tracking services use received AIS data to visualise vessel movements, but the information should not be treated as a replacement for professional navigation systems.
AIS Class A and Class B
AIS Class A
Class A transponders are used by many larger commercial vessels and passenger ships subject to applicable carriage requirements.
AIS Class B
Class B devices are commonly used by smaller vessels and pleasure craft that are not subject to the same requirements as larger commercial ships.
Shore AIS
Coastal and port receiving stations collect vessel transmissions within their reception range.
Satellite AIS
Satellites equipped with AIS receivers can extend vessel tracking coverage into areas far from shore.
