Celestial Navigation

     Or, the stars may not actually hold your future

I just read online about a Great Schism in sailing. The publication Ocean Navigator reports that the Coast Guard Academy will continue to teach celestial navigation -- navigation using the stars, the moon and the sun. Amazingly, the  the U. S. Naval Academy will be moving in a completely opposite direction, They will rely totally on GPS technology. Presumably they will have redundancies built in -- more than one chart plotter, and probably more than one brand of chart plotter.

Those sticking to celestial navigation will have a little more difficult time with redundancy strategy. The obvious strategy there is to have two teams performing their calculations completely separately. However, that won't solve the problem of extended, heavy cloud cover -- for instance, in a hurricane, where it might be extremely important to know exactly where the ship is, which would identify which quadrant of the storm the ship is in. The four quadrants of a significant hurricane vary significantly in strength, so obviously, being in a weaker quadrant can be a valuable strategy.

But practically speaking, for the newer sailor, they need to know accurately where they are. We can talk about dead reckoning -- and it can work -- but only an idiot would rely solely on dead reckoning when it's a new skill. Likewise, using sextants involves using multiple charts along with taking accurate positional readings for celestial bodies, on a pitching boat. It isn't going to be terribly reliable for a newer sailor.

Celestial navigation is difficult and expensive to learn. There's no doubt it works, when you can be sure of the time and actually see celestial bodies -- but it's not fast, and there are meteorological limits.

We've talked about this chart plotter debate before, and I'm going to come back to my earlier suggestion that you use a chart plotter -- actually two. If you have a hand-held backup chart plotter and your electrical system goes out, you will still have very accurate access to your latitude and longitude.

Mark those readings on your chart at an accurate time table -- say, every half hour. Then you'll have a visual representation. You can easily compare this to your efforts at both dead reckoning and celestial navigation. 

I'm not saying that celestial navigation should go the way of the dinosaurs. Clearly, many find real value in it. I'm also not saying that chart plotters are for lazy people. But in fact, a chart plotter can you assist you as you learn both celestial navigation and dead reckoning by double-checking the conclusions you drew from the older methods. And in an emergency, let's face it -- for most people a chart plotter is going to give you information more rapidly and more simply.

Chart plotters are not the tools of the devil, and those who use celestial navigation aren't inherently superior to others. It's just a matter of interest for the great majority. So be tolerant -- "The farmer and the cowman should be friends!"

Bottom line: don't let those who know celestial navigation try to lord it over you because you don't know it yet. You're a newer sailor, and that's NOT a moral flaw. Maybe excessively harsh judgment of those coming behind one IS a serious character flaw. NO ONE PERSON represents the minimum standard to which all must line up -- especially when that status of "I'm the best and the rest of you are unworthy" is self-appointed.
