Arrived early but took me almost 2 hours before I was ready. My upper batten had too much tension and I lost the screw somewhere in my sail after some probs with my extension, so needed to derig and rig my sail again and again... It was the first time with my 7.8 (apart from yesterday on the tandem) and it has a very deep profile...much deeper then the 2016 7.8 from Dirk on the same mast (I use no spacers...). Leaps of power on the water, 7.0 would do as well for me most of the times. 

Tested a Select Vmax 31 from Dennis and compared it to my Select Crossfire 31. The Vmax is probably a bit faster, but had a few spinouts (especially upwind, low speed). The Crossfire is a more allround speedfin which gives you the confidence you need all the time. If you aim for the highest speed possible, the Vmax is probably a better choice.

Nice topspeed for me with 7.8.

Nice morning session with many friends...
