    George,
    
    Let me put it this way.  I have 3 computers on the boat (helm, galley
    and berth).  I have and use sight reduction software about half of the
    time.  I have e-charts which display at the helm and the galley.  I use
    paper charts, tide/current tables, log/trig tables, slide rule, stubby
    pencil and a BIG eraser, sight reduction forms and tables as well as
    lots of scrap paper.
    
    What I my students that you use any method available (computer,
    programmable calculator, calculator, log/trig table, slide rule, or long
    hand) but if they need to know how to develop their answers by hand -
    notice I did not say that they had to be comfortable - just know how to
    get there.  This holds true for DR. piloting, e-nav (radar) as well as
    CN.
    
    From what I have seen, not many folks use CN the way that I do - just as
    there are few who are prepared to develop manual DR plots and determine
    actual set & drift calculations either.
    
    I use the long hand calculations because I enjoy playing with the
    numbers.
