RE: Different technique required for isonic 101 for speed compared to traditional shapes?
I spent some more time on is101 and found some things that made me faster.
I raised my boom quite a bit comparing to my old sonic and I set my footstraps really tight so my feet are very much at the edge of the board. I also played a little bit with mast base and found that it is faster when back. It was really choppy so I had it in the middle position, but I think that in flat water and downwind runs it could be really good if placed back.
I also found that I had to adjust my stance with isonic compared to sonic. I am much more far out from the board and a little lower, similar to highwind formula sailing so I am also thinking about longer harness lines also.
By the way, what is your best speed on is101?
