Re: Traditional Navigation
Celestial is worth knowing just because, IMHO. It's an elegant solution to a problem and it ties us to a long tradition. And someday, it just might come in handy. But even if it never does, not all knowledge must be strictly practical.
Basic skills in coastal navigation remain essential. Most chartplotters will not keep you out of harm on shoals, obstructions, etc. It's essential that you know how to read a paper chart to get the "big picture" that you can't get with a 5" screen. You can zoom in, zoom out all day long, but it ain't the same thing.
