Ship Tracking: VesselFinder offers a real-time ship tracking service that enables users to monitor the positions and movements of ships and vessels worldwide. Users can search for specific vessels by name, IMO number, or MMSI number, or they can explore maritime traffic in a particular area.

Vessel Details: Users can access detailed information about individual vessels, including their current position, speed, course, destination, and voyage history. Specific technical details, photos, and other data related to each ship can also be found.

Premium Services: Similar to MarineTraffic, VesselFinder also offers premium subscription plans that provide additional features, such as access to historical data and ship image archives.
