5/5Excellent program
Had this installed for a while and I’m now beginning to use it. Integrates well with my Wind Instrument. The building of routes and importing waypoints stumped me but after reading the Help document. After working with the app and companion app Boat Beacon, I am really impressed. Excellent response from help desk/support and they want user feedback to guide their future app updates. I am changing my rating from 4 to 5 stars.

5/5Not picking up no Vessels or ship traffic
I am not picking up no vessels or no ship traffic at all on this app and I just got charged last night another $30. Thinking about canceling this app

5/5Intuitive and accurate
I have had SeaNav for a year now and have learned to trust it. It is just as accurate as any high dollar system and is easy to use.

5/5Wouldn’t sail without it!
Love knowing what went buy in the middle of the night when anchored. And what’s coming by before I can see it! Catalina 380 Hull 123

1/5Misleading marketing do not buy
They do not make it clear that chart purchases are required. To make it even more misleading I can’t use the charts Boat Beacon which I already purchased from them. There was a link in Boat Beacon to SeaNav saying I could navigate with SeaNav and show AIS overlays on the charts. Well now they want me to repurchase the charts I already bought from them
