Good morning all. I installed this chart program on my netbook, which uses NOAA charts and seems to work pretty well. I downloaded v1.3.6 for Linux at http://www.opencpn.org/ and the associated charts for Southern California (Coast Guard District 11) at http://www.charts.noaa.gov/ENCs/ENCs.shtml. They have versions available for Windows and Macintosh as well. Steve
