Excellent 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.

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.

SeaNav autoroute: Set start and end point for a route and let SeaNav propose a route and waypoints. SeaNav AutoPilot: Navigate routes automatically. SeaNav can now remotely control Raymarine and Navico/Simrad/Lowrance Auto tillers and helms. You can also use the free SeaNav Apple Watch app to control a Raymarine autohelm and tiller from your wrist.
