Has anyone here used some kind of navigation app for paddling rivers (or, say, for paddling in Puget Sound (near Seattle) at night)?
Specifically, I'm looking for an app that would allow me to put in some GPS coordinates for sections of a river where one channel is better than another or to avoid rocky areas that aren't immediately apparent while reading the river on the go. The app might alert me with verbal cues (in 100 feet, go right) like Google Maps driving directions. Or the app might just show a big right arrow.
Thanks,
torsten
