Another great testing day. Started on the 7.8 and then changed to the 7.0. Sailing with Twan, which on one hand is great as he is about the best reference in the world, but on the other hand very demoralising. He is very very quick, but it meant that when I changed to the 7.0 and could almost keep up with him, I knew it was a very good sail!  Didnt really do many speed runs on the faster 7.0 setup, so top speeds are down compared to the others, but still Twan had a peak of 39.5kts, which I have no idea how he did!
