there are two or more, 'seaclear' and 'opencpn' seem to get good reviews. do any members have an opinion or comment to share on which is superior?

 I am also looking for a source of free or low cost e-charts for areas outside the USA. does anyone have a source??

 

thanks

This link from the SSCA Forum does a pretty good job of compairing the two http://forum.ssca.org/viewtopic.php?f=12&t=11428

thanks for the link, looks like openCPN is the way to go.

 It looks like i need CM93 (v2) charts to get it going -- does anyone have these downloaded that I can copy on a CD or memory stick?
