I found some open source software for converting the full size NOAA charts that are online and wrote up an article on how to download, convert, edit, charts. The cool thing is that you can make a chart for just the area you sail in. For example, my boat is at the border of two NOAA charts. Now I can print a chart of my area that overlaps these two charts and leaves off the parts of the charts I never visit.
While there, check out the weather tab if you have not done so already. Also, lots of engine manuals and other stuff in the reference tab.
