There doesn't seem to be much discussion around set-up for women kite racers. Do they use the same size fins? or smaller eg 38cm.
It would seem that the top women still use the same 70cm wide boards and don't opt for anyhting much narrower.
Appreciate any advice
It goes by weight and not sex
check out Rista website. He has a fin selector, which is basically based on weight. Personally I think there are a lot more variables to worry about for fin selection, but that is me..and I am not very good at this.
In addition to weight I would assume the leg strength is important.
