    Re: Fix by equal altitude sights around local apparent noon
    From: James N Wilson

    Malcolm Misuraca states: "corrections for movement of the vessel
    for those who want to reduce the small error induced by the difference in
    position of the boat between sights before and after noon."
    The error isn't small. I have experienced disbelief by knowledgable
    people that significant errors could be induced at sailboat speeds. The
    first time I tried the method without correction for vessel motion
    resulted in a seventeen mile error.
