    Doug, I do sights using Dip Short in the harbour or anchored in small coves;
    natural horizon either on shore points near here, or anchored out in the
    Strait; and natural horizon running during our cruises.  My sights are out
    by about 0.5-4 miles using Dip Short and natural horizon on shore or at
    anchor, and by about 2-6 miles while running.  I don't know why I practice
    CN, except as a distraction from the stresses of my real job, and a love for
    the skill.  I'm getting a bit long in the tooth to make the circumnavigation
    that I dreamed about my whole life, but never got around to.
    
    I really want to give the sextant a try on blue water some day.  I've been
    trying to find a way to get to sea on a 2-4 week ocean trip, either a
    passage on a commercial ship where I could keep my own DR/CN plot and then
    check it against the ship's log at the end of the trip, or a leg on a
    cruising sail or powerboat.  I'd take leave from work, and then the family
    could meet me at the end of the passage for a holiday before returning home
    to reality.  Any suggestions welcome.  Do freighters/tankers take passengers
    these days?
