Do we need it or is it a forgone art that is no longer needed?

Read "Adrift - 76 days lost at sea" by Steven Callahan and see if knowing at least a little about celestial might come in handy.

Aye the book defiantly points out how all mariners must know something of Celestial Navigation.

you need it all electronics will fail. murphy has proved that. Get a good metal sextant not a plastic they take too much adjustments and practice. There is a great joy in finding your way to a distant landfall using celestial navigation.

CELESTIAL IS A GREAT MENTAL STIMULUS AND AFTER YOU LEARN SOME OF THE BASICS AND PLOT YOUR FIRST NOON OBSERVATION AND REALIZE THAT IT IS CORRECT--WHAT A GREAT SENSE OF ACCOMPLISHMENT. AND BY THE WAY ELECTRONICS DO FAIL. CELESTAIRE is a great source for everything you will need including instruments and plotting sheets as well as almanacs and publications. Try it, you will like it.

I spent 4 years as an aircraft navigator. LEARN CEL!!! Murphy lives and you''ll be glad you took up the practice. Even a sunline can help when desperate. Don''t forget Polaris at night.

All you nay sayers of electronics need to read Webb chiles article in SAIL MAG 2001. If your so desperate and can''t figure out a compass and in a life raft who cares, I''d throw overboard all but a pint of fresh water and six saltines for two thousand dollars of good electronics in any sitituation.

I''m not so sure I buy the part about metal v. plastic sextants, though I realize it is the common wisdom. You ought to check the calibration on any sextant before you try to take a shot, no? How much can the material expand/contract if you take your shot within a few minutes of correcting? I have a Davis Mk something (the one with the beam converger) and can shoot a sun/moon fix within a minute of arc, using the GPS as a reference. I do agree that I want my electronics aboard as well; no substitute for a Celesticomp! ;-)
