"Emergency Navigation" is a great book--forgot the author's name.
There are lots of good beginning navigation books and some good videos.
William F. Buckley (yes, THAT Buckley) is an avid sailor and HIS video on celestial nav is very good--he goes for the Air Nav tables.
Then there's the Lighthouse one the begins....
"Murray"
"Murray, wake up!"
"Murray, wake up! I think we're lost....."
Plus there's that GREAT PBS video: Longitude, based on the wonderful book by Dava Sobel. It's almost like a Tom Clancy novel, it's so dramatic. I have pictures in my office at work of Harrison's first sea clock, the H1, that I took at The Old Observatory in Greenwich....before they yelled at me about using a flash...H1 to H4 are incredibly beautiful, and Harrison was such a genius--like the 2 bicycle makers who wanted to fly so they reinvented the science of aerodynamics--the Wrights. Or the guy who wanted to build an electric motor so he developed the laws of electro-magnetics!--Maxwell.
