As far as I know you can kite on Hamo. A few years back Robbie Treharne had his gear up there during Race Week and was launching on the Resort side beach. Its pretty gusty in a Sou easter on that side though, there would have to be some great spots up there not necessarily on Hamo though. Ideally access to a boat would be the best to get you to Whitehaven or other spots, I think over in Airlie beach theres a few points that'd be good for it.This time of year the SE trade winds are pretty reliable with solid 15-20 knots most of the time. Not really sure what its like in the wet season (Xmas) but I know this much- it will be friggin hot and humid and I think you gotta worry about stingers (box jellyfish) too.
On that subject I'm off to Race Week next week, is anyone else going? Any one thinking of taking there gear? I may do it if theres anyone else around, especially someone with a speed boat

!! I'll supply the beer if you got the boat!! Let me know if your keen.
