For others interested in this kind of thing there is also SailBlogs (http://www.sailblogs.com ) has feeds of sailing travels. There is a 'system-wide' kml file (showing the current positions of a lot of the member boats), and premium members can have a personal kml file tied with links to thier blogs as well that is created automatically.

So if you're interested in reading about sailing adventures, or have a trip of your own to document, this is a great site.
