Ah ok, thanks guys, I had a bit of a look at the Lake Eyre yacht clubs website (they had a regatta in july 2010) and it I found some guys in Cats and also some kite surfing,

It might be too shallow, but i reckon the locals might lead me in the right direction. I think you might need a 4wd to get in as well russh, lucky i just picked myself up a cruiser

. I reckon i'll take the standup just in case too....
this is their website in anyone is interested.
