Perhaps it's because so many of the guys in this sport come across as complete knob jockeys? The behaviour & attitudes of some of the 'higher profile' members of the sport wouldn't help much......imagine being a girl and picking up a copy of Aus Kiteboarder mag to see what the sport is all about?

The behaviour & attitude of lots of the guys in forums like this is equally lacking in appeal. Every time my GF has a read through any of these forums, she comes out afterwards and says 'Geez there's some dickheads in there.'
When my GF started, she did say that she was disappointed that there weren't more girls kiting in our area. At that time, there was only one other semi-regular girl kiting apart from her. The other girls who used to be regular kiters have either moved away or have other things going on atm (kids etc) and don't have as much time to kite as before.
She also took a while to overcome the fear factor with how much power the kite could generate, which is something I think most guys are immune to initially (the '10 feet tall and bullet proof' factor.....the same thing that makes young males plough into solid objects in cars at high speed).
But, she's still at it and making progress all the time, so I'm glad she stuck at it
