Just as Planefinder.com finds planes in flight, Shipfinder.co finds ships, using ships’ AIS (Automatic Identification System) signals. A ship’s AIS signal contains its identification, position, course, and speed.
All passenger vessels and all ships of any kind over 300 tons must be equipped with AIS transponders.
