    Re: sextant without paper charts

    Robert Eno, you wrote:
    "Have to disagree with you on this one Frank. I have spent a lot of time
    noodling around with the SR tables in the Nautical Almanac and in my humble
    opinion, they are far too convoluted and complex and therefore does not lend
    itself to emergency situations where everyone is stressed out and already
    liable to make mistakes."
    When I first wrote that post, I typed it with HO211 as a compact method, but
    changed it to the NA method thinking that HO211 would sound archaic. If you
    could compare 211 with the tables in the almanac, do you think one is
    clearly superior for compact tables?

    "But at the end of the day, it seems to me that HO 249 is the way to go. Two
    volumes and you can go anywhere."
    Probably a good choice.
    Another issue: since we're talking here strictly about navigation in a dire
    emergency, we also need to consider the possibility that the single sextant
    aboard the boat has survived, but the three to five men with navigational
    knowledge are incapacitated. This gets us back to real lifeboat navigation.
    What minimal instructions should be included in the sextant box to get the
    vessel to a friendly port under the assumption that no one with proper
    training is available? This, of course, is where I would recommend something
    like "latitude AND longitude by noon Sun". That technique can be learned in
    a day by a "well-motivated" student, and you can cross an ocean with it.
