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?
