Navionics just released an update of the Boating App that boasts Auto Guidance . With it you can select a starting and destination point then Navionics will choose the most efficient route using your entered parameters for draft, range, beams and bridge clearance. It’s easy to use and once the route is calculated it can be updated to your Garmin, Simrad Yachting, or Raymarine chart plotters. Watch the video to see how it works on an IPHONE 13 | Boating Magazine
