    Re: Why do we ocean navigators defer to 249 when 229isbetter?

    By the way, in some bookstore or online , is it possible to buy the original H.O. 208 manual, Dreisonstok? Letcher's book is pretty good , but  I don't like carrying it around .  And I really don't want to photocopy or print 80 pages. Ween's  LOP 1927 is 51 small /medium pages.

    Also, I often check my 249 sight reduction with my TI 30.....sto1,2,3 go! Really quick.

    To paraphrase Frank Reed, "Computing power is cheap." A NA and $10
    TI30XA does it all.

    Score 1 for the cosine method.

    Current tabular methods can be done manually if you can add and subtract
    DMS in the sexagesimal system. No electricity required.

    Score 1 for tabular methods.
