I took an intermediate lessons when I was living in Hong kong...communicaton was difficult, lets just say his english was better than my cantonese. However it was definitely worthwhile, I picked up a lot in 2 days, some things I wouldn't have learnt by myself. The guy was actually a very good teacher, obviously had been doing it for years, and he made it a lot of fun.
Having said that - isn't there also something perhaps more rewarding about teaching yourself stuff...i figured out harness & footstraps by myself and am glad I did.
Does anyone actually run lessons in Sydney? I'd pay ohhh at least 50$ if somebody can teach me to waterstart

the last time it was windy enough to try I just got too tired after an hour or so, although I did manage a waist deep beach start.
