The entire task of navigation rests upon the Navionics app, installed onto all of our mobile devices. Its depth maps, compass, GPS, waypoints, community edits, and more, are all the features that we could ever wish for to get from A to B, over water. We use it along with a separate AIS app for traffic.

We carry a sextant aboard, and both of us are learning to use it. Depending on GPS isn't ideal, and learning to navigate without it might save your life.
