Before practicing old school windsurfing on the dufour wing (next week there is a competition called ODSC - old doors surf cup), I went out with the iSonic for some runs enjoying the eastern wind and nice sun. 

Old school windsurfing was 'with obstacles'. First I tried a Wayler 320 but fin broke (lying in a garage for 20 years is nog good for plastic) and the dufour sails is a bit too big for the wooden boom an was catching too much wind.
