Having problems with message search?
I put up my track as well. You can see it here
http://www.mowind.org/wp/wp-content/uploads/2008/09/tdcjsw3.jpg
I tilted the earth to give it a little perspective.
The conditions were definitely interesting. I got left in the dust right away but managed to pass a couple of people on the way back.
The course we ran was 6.8 miles up river and then back down and seemed to work well. I have the results by mark rounding. Notice that the fast guys took an hour to get up river then 20-some minutes to get back down. I was 15 min behind on the way up and lost another 30 min on the way back. I would definitely like to try that again. Placement on the river was an important tactic. There were many places with swirly, or worse, no wind. There were also lots of opportunities to surf on the wakes of passing boats, provided you had enough speed to begin with.
Next year it will be fun to have more races. I think two on Saturday and one Sunday Morning would be good.

Subject: [mowind] Tour da Croix gps track
Two weekends ago, Arnie Cleveland put on a very successful inaugural running of the St Croix River on the border of Wisconsin and Minnesota, dubbed the Tour da Croix. He also just posted some very nice pictures to the photo section of the Yahoo Group page. I also posted some screen grabs of my gps track overlaid on a google earth map. FYI, wind was nominally out of the southwest, but we experienced shifts from every point of the compass along the way, ranging in speed from 0-15 mph.
In the zoomed-in picture of the top portion of the course ( http://sports. ph.groups. yahoo.com/ group/mowind/ photos/view/ d14c?b=30&m=f&o=0 ) you can see a relatively straight section of my path running from north to south along the eastern bank as we made the return to Point Douglas. During that time I was able to avoid having to tack back to the middle by getting fortunate lifts every time I got near shore. Up until that point, Peter, Blaise, Adam, and I kept trading places in the challenging wind shifts. You can see that most times I went towards the middle of the river on port tack prior to
that, my course is nearly back upriver, over 90-degrees from the path of the previous tack, rather than the 45-60 degrees you expect for a longboard tacking upwind in steady wind. So, once I was able to avoid tacking by playing the shoreline
shifts I was able to put distance between me and the rest of the guys stuck tacking in the middle.
Other info from the gps are:
* Total distance of 15.47 miles sailed
* 161 minutes of recorded sailing time (~5.8 mph average)
* Max runs of 19.5 mph (2-sec) and 18.1 mph (10-sec) during the 1st half of the downwind/upriver.
Overall the event was a great time, and I hope more people show up next year.
Later,
Arden
