I have had more than one occasion where my Garmin handheld picked up zero satellites when I had a clear view of the horizon. At least once was while sailing in open waters, and the condition lasted a couple of hours that time. I gave up waiting, but it worked again the very next day (no change of batteries or anything).

Please note: I was navigating commercially across the Oceans long before they had GPS. And really don't need a GPS to get me from point A to Point B.

Me too but now that I have GPS . . . . . it's a little like trying to find a call box when I could have a satellite phone in my hand.

... which might be a good idea, so that you aren't all rusty at finding call boxes once The Man or The Sun or Zeus or whoever comes and shuts down your satellite phone. Assuming you're concerned about that.

The OP asked for any book recomendations.

Celestial Navigation for Yachtsmen by Mary Blewitt demystifies the process.

I liked it and know of many others who also learned from it.

BTW GET A PLASTIC SEXTANT TO LEARN ON! Lots on fleabay. You might even find one is a marina skip!

Back to the original question:

Ya - if you feel like it - it is not hard to learn. Trig is NOT my strong point, but, you don't need to understand trig to do elestial nav.

My wife and I both took Celestial Nav (and both passed it) with the Canadian Power Squadron group - and it was fun. Taking sites is not all that hard to do and neither is working out the positions. Just takes patience, practice and someone who can teach it to you.

If you are inclined - go for it.

CN is really a case of use or lose it. I took the course 20 years ago. Trying to get back into it using Tom Cunliffe's book.

I have often used CN to back up GPS and vice versa. It's a good tool to have in your toolbox. You never know when it might just save your butt.

For me it offers a direct connection to all the mariners that have gone before and that alone makes it worth learning.

Also, I believe as sailor anything increases your connection to environment is a good thing. When I sail long distances I get into a routine of regularly logging such things as sea state, barometer reading, wind direction and strength, clouds, and a host of other variables that affect sailing. CN dovetails very nicely into this more traditional, less automated, mode of navigation and sailing. Taken as whole, this practice has taught me more about the art of sailing and made me much more appreciative of the unique gifts that sailing affords than I believe could ever get from simply pushing a button on a GPS.

Don't get me wrong I have pushed more than my fair share of buttons

Do what you makes comfortable and increases your sense of security and confidence because that is what will help you over the horizon or across the bay. How you do it is often times less important simply doing it.

Just my .02 cents.

Not try to change the topic here.

If you need to ditch you SV and climb up to the life raft. Beside the other essentials, what would you rather take, GPS with spare battery or your sextant charts, calculator and etc.

Let here from the both sides.
