I was warned about the limited detail that the Garmin electronic charts gives you for Cuba. And that turned out to be an understatement.
The picture posted below will show how poor the data is for Marina Hemingway when using the Garmin charts.
The picture in my next post is a screenshot of that kind of detail you get with the Navionics electronic charts of the same area.
As you can see by my track in the picture below, according to the Gamin chart, I was docked on the hard.
Bill, do you have the optional "SonarCharts" on your Navionics? (If you click the blue logo in the lower left corner, you can toggle between charts,,,Govt Chart, Navionics, SonarChart.)
