The free AIS ship tracker VesselFinderhas added live ships map. It has no so many features like MarineTraffic but if you just need to find a ship it is faster. It also uses OpenStreetMap platform instead of Google. Give it a try…
The coverage doesn’t even come close, Marine Traffic is a much better platform and has more useful detail. IMHO, this VesselFinder AIS version is not even close.
