    Re: instances of the use of "horizon grazing" technique
    From: Lu Abel

    About a decade ago an adventurer did a single-handed circumnavigation
    with absolutely NO navigation instruments.   I remember that he timed
    his passage of Cape Horn to allow him to judge that he was at a safe
    south latitude by this "horizon grazing" technique.   Unfortunately I
    have no further recollection of the name of the boat or its skipper.
