You can get most of what you want to analyze from GPSActionReplay...but it takes some effort.

Here are a set of tracks recorded on the Tornado during the MidWinters regatta out of Mission Bay San Diego (I could not attach this 800+ kb file to this post...100 kb limit...you can save the file from your browser)
