    Re: Looking for references on "aiming off"
    From: Gary LaPook

      The best place to get information on "aim-off" is at my website at:
    look at "topics" and "discussions."
    In early days of marine navigation when it was not easy to determine
    longitude it was common to aim off to the east or west of the
    destination, sail until reaching the latitude of the destination, and
    then sail either east or west to the destination. This was called
    "latitude sailing."
