Interesting session. Sailed asy left and right . First real session with asy (did it only one time before but hit a sandbar after 10 minutes and broke my mast). Wanted to get some confidence with the speed boards and the asy fins. Sailing upwind was not a drama too with those fins. 

Wind started relaxed and my 5.8 was stable all the time. But at the end when i had to leave the wind picked up and ended with hugh 44 knots ghust when I had to leave to prepare dinner. Happy I made it to the rigging place... it was quite challenging. 

also tried i99-53. I expected it to be faster but it was not. Somehow it does great on the Amstelmeer, but in flat water i do not reach the same speeds....
