Finally i had the chance to sail at this crazy spot.
First run started full power and combination board/sail/fin was fully in control.
Max. speed 82/u and 10sec. 78,55/u -> a new pb.
Second run also good speeds, it was looking good at that moment to sail a very good 5x10" avg this day !!!
Sadly at that moment Benjamin did a crash and i stopped sailing to help him and i called 112. Stupid, they refused to send a boat so Benjamin had to walk back to the shore with a totally broken hand/arm !
Session over for me too.
