At sea who cares where the chart plotter is? Close to land one needs to be looking at bouys, markers, land and water. The plotter will only get you in trouble IMHO. Ask all the sailors that have hit markers, run aground because the bottom can't read the chart plotter or gotten into any other trouble relying on a piece of equipment that is about as accurate (often) as a chimpanzee picking a stock portfolio.
