[Rhodes22-list] Navigation Electronics

[Graham Stewart]

Tom:
What sort of navigation equipment you need depends on the circumstances
under which you would use it.
My sailing is restricted to day sailing in familiar waters so my needs are
modest. I use my cell phone and sometimes a tablet and for navigation use
"Sail Free GPS" software. This app runs on both my cell phone (iPhone 8+)
and my tables - a generic $200 android. SailFreeGPS has a free version and
the paid version is, as I recall, under $20. It is actually very powerful
and used by some for transatlantic voyages.

My suggestion would be to download the app and play with it over the winter
at home. You might find this is all you need and will certainly be useful
training.
