Thanks for the input guys, to be honest we have tried most of the advice above and she is slowly improving managing 5@24 last year, we take her up in 1k incriments.
The boat is a 3yo stripped out TXI, maybe the wakes just look big as she is only 5ft 0, I like them at 22off 32mph compared to other tournament boats I have tried.
@ScottScott trying to get a laugh from a Brit with a link to a US sitcom is like you guys trying to watch a German one, if there is such a thing o:) .
In the meantime I am going to get her to watch TWhisper showing us how it is done.
