I just tried Ed Popko's postscript files.  Postscript is a good
language for this sort of work (and I am old enough to remember when
we had to program in it to draw stuff on laser printers). Ed's code is
well documented and easy to customize without any knowledge of
PsotScript. I changed the paper size to A4 for example with these
lines

/wid {595 pt} bind def            % Paper width A4
/hgt {842 pt} bind def            % Paper height

replacing

/wid {8 in} bind def                % Paper width
/hgt {10 in} bind def            % Paper height

for example.

Is the idea to print them out for the Lat and Long that you expect to
sail before you set off? I have not had much luck with a printer on
the boat.  Isn't that where the ones with just a compass rose and you
draw your own scale win?
