I am giving this ***, but will review as new versions appear. I got this app because it will overlay AIS over Navionics charts. So that is what I've played with so far.: Navionics works well.AIS overlay worked first time from my source. The data it displays is pretty limited: no boat name, destination, type etc. The most annoying thing is that if you go into a menu or put the app into the background it falls back to a zoomed out map. It is also not very touch sensertive when other apps are ok
