    Lunar Distance
    From: Gordon Talge
    Date: 1998 Jul 23, 2:27 PM

    My understanding was that since voyages way back in the
    days of exploration were sometimes years and they would lay
    over places sometimes months at a time, that lunar distances
    were done on shore to establish time for the ship's chronometers.
    In addition to the math, it took sometimes up to four people to
    to a lunar distance.
    If I remember right, Columbus tried to establish his position by
    use of a lunar eclipse on the island of Jamaica. His results were
    pretty far off considering he was on shore.
