    Hey, John, thanks.  It's always good to hear one of my children found a good home. The book came out in as a book club hardcover in 1975, then later in a trade paperback edition - When did you buy it? 

    I used the Ebbco thru two sailing seasons, then got a metal sextant and an early Seiko digital watch, which was clunky but had a steady rate.

    Thanks again. You've made my day.

    Your message brought back some good memories for me.  I learned cel-nav from my navigators when I flew in the Air Force.  The first book I bought on navigation was "Common Sense Celestial Navigation". By then I had a TI sincetific calculator ( with the red display) and hated the 9.xxxxx log tables so I never really looked at the tables in the book - I used the formulas.

    I even went out and bought one of those ugly, black plastic EBBCO sextants.  Still have it and the book.

    The book came out too late to have much impact I think.  HO 249, trig calculators, computers and all overtook log trig tables.  It takes minamialists like me ( and you I think ) to like the back to basics paper and pencil way.
