There is a posted trac of Windrunner sailing a triangular course just south of the bridge on the upper Neuse. Go to http://www.ipass.net/sailboat/ (Used Sailboats) and the link on the C-27.
The winds were sort of out of the North at 12-15 with gusts to 20+ kts. The jib used was a cut down stock 110 probably about a 90 with a full main. The boat was really heeled over, with a bunch of weather helm fighting gusts.
Keith asked me to run the course twice, unfortunately the gps timed out.
We reefed the main on the second run. It was a much more comfortable run and I think faster since there would have been less leeway and less weather helm (dragging the rudder through the water).
Near as I can tell the average speed was about 4.3 kts.
I know that racers use such trac plots to rerun races and analyze results, but this is the first time that I have seen such a plot and found it interesting.
Smooth Sailing
