Stupid me. Forgot to insert the SD card. There was no track stored on the device. I was curious about the total distance and Alpha. Ah well.. 

Max was 62.49.   Sail was to small. Had no power downwind. Made the two fastest runs when I went back to the car in the 'chop'.  In the beginning the wind was not so strong so I gave the sail a little bit less downhaul hoping I coud get some more power in the sail. Shouldn't have done that. It felt less comfertable.  But it was a nice exercise. Very nice weather and a lot of surfers.
