RE: Different technique required for isonic 101 for speed compared to traditional shapes?
Thanks for the quick reply.
I already apply lots of downhaul in my sails. Most speedies (including me) use more downhaul than prescribed (and a bit less outhaul). In my case +3 cm.
The board already runs free. On beam reach the speed is good. But on downwind, the board does not get into 6th gear. It goes faster than beam reach, but only a little bit. Not the ferocious acceleration I'm used to when you turn downwind from beam reach.
