Just one of the many flaws of using a chart plotter to navigate once you are within sight of land. I certainly will get flamed but the prudent mariner knows how to use a paper chart and uses the paper and tools first any only uses the chart plotter out of sight of land to confirm the work on paper. The guy had no idea where he was in two or three dimensions. When you can see land cover the display and get your head out of the boat.
