Yes!  I'm very happy I finally went windsurfing again with the GPS. Latest session was from 2009. I didn't do much windsurfing last 3 years and this being my second session this year I really had to get used to it again. Cost me alot of power but at the end I noticed that my technic was getting better and I managed to get some 60+ runs. I'm very happy with the results.

Weather was great. Sunny and windy all afternoon. But had to quit because I had no more power left. Hope to pick up the GPS surfing again. More of these day's please.
