I found racing against kiters in very light winds pointless.
To make fair comparison we should use the same size sail and kite - and still will not be to fair since
wind speed higher above the ground is much better.
dude on the racing kite gear is hammering along. Interesting to see the board having fins near the rail under his front foot - if this is normal excuse my ignorance I know nothing about kite gear.
This is a better guide, but they run slalom not Formula.
The results are likely to depend on the wind strength and if it was course racing, would probably depend on the course set as well.
In 2011 the windsurfers won this, in 2012 the kiters won, in 2013 I think there probably wasn't enough wind to run it.
