I was quite early on the beach and checked the conditions. The sand was flying around, the sea was completely white, the water level was very deep, there was already a little swell and the waves broke at the sandbanks. 
I was still alone, but I used the time to rigg my 5.1 Speedblade.
After some time Sander, Michel, Wouter and Jean-Marc arrived.
Jean-Marc first tried out whether the conditions were sailable. Wouter and I soon followed.
We found a short area of smooth water and were able to make some runs at 50 knots plus and square conditions.
I was able to reach over 80 km/h Max several times.
The new Speedblade 2018 was very balanced and easy to hold.
The PD Speed 43 as usual super fast.
The BEAST ASY S 20 from http://www.feinefinnen.de/ provided great control under these epic conditions.
Thanks to Sander for lending the RDM extension and thanks to Michel for the great pics.
