Barbara, I happened to see a Swedish families website this a.m. and, to make their Sweden-Caribbean routing chart, they did started with an image in the appropriate scale from their electronic charting software
(I think it was Maxsea). If you don't use nav software
, perhaps a friend in the anchorage will allow you to dump the necessary image to a disk or thumb drive which you can then take back to your boat. Just another thought; personally, I felt the Mapquest image was a bit 'funky' for your classy site.
