We will do our best to solve it. Thanks! Visibility of vessels in the App depends on AIS signal availability. If a particular vessel is out of our AIS coverage zone, VesselFinder displays her last reported position and updates it as soon as the vessel comes into range. Completeness and accuracy of the information provided cannot be guaranteed.
