READ THIS IF YOU WANT TO HAVE A GREAT LAUGH! :) 

I went on the water with my Speed50, 5,0 and 23 weed Asy fin. I felt a bit insecure at first as I have not been on a speed board for 2 years. Hardly not been on smaller gear than 110 slalom and 7.7 in two years so the speed feeling did not come naturally. After struggling for a couple of hours and being frustrated for not getting any grip in the course with my brand new assy fin I spoke to Markus about it. He asked me about the fin and I said it was assy with the flat side towards the wind. You get it! I had been sailing with a baboard fin in La Franqui! Haha! No wonder I even overtook the champ on the tack back. :) :)

So these speeds are all on the starboard tack with a baboard assy fin. :) :)

I´ll certainly be back for a rematch!
