    Strangely enough,
    always living far from a sea,
    and having little oppotrunity to sail
    or talk to sailing people,
    I really thought that Celestial Navigation was dead by
    the end of the 1970-s
    until I discovered this list:-).
    The first sign of decline from my point of view was
    the spread of calculators in 1970-s.
    One important part of the pleasure, computing with the
    logarithms, was gone forever. Shortly after that I learned of
    the artificial satellite navigation (pre-GPS) and
    it became clear to me that Cel Nav will be dead in few years.
    Many years later, I saw an ancient sextant in some marine
    gift shop in California, and was considering buying it, for
    "sentiomental reasons", but was afraid that my friends
    will think I am crazy:-)
    So a discovery of almost
    200 people discussing Cel Nav (and even Lunars!!)
    on the web
    was really unexpected.
    (All I knew about lunars was a mentioning in a popular
    book about Cook and Bougainville that they tested the
    "method of Lunar distances" of determining longitude.
    This sentence was enough for me to understand the principle
    of what they were doing, though i did not realize the
    complications coming from the
    Moon shape compression by the refraction.
    But I
    thought this
    was completely
    forgotten when good and non-expensive
    chronometers became available.)
