If any of you are looking for good, free charting software, the
developers of OpenCPN have just announced the availability of
release1.3.4, available he

http://sourceforge.net/projects/opencpn/

I have already installed in on two of my PCs, one XP and one Vista,
both are working well. The new release adds a very nice track
logging feature with import and export of logs, and fully adjustable
logging intervals by either time or distance. It is a quick
download and easy install.
