After today, I retract my comment about wanting to have a crack at kiting...
Spent the arvo in the bay, 20+kts, bump'n'jump with 3 other guys, playing in the waves and basically having a ball of a time.
As we were carrying our gear up the beach (completely spent

) I noticed a lone-kiter setting up on the beach, I wandered over to see if he needed a hand.
He asked me to get the kite in the wind zone, and all's good from here on in, at this point, as he nodded, and I released his kite, he powered it up and got dragged along about 10m before losing his footing and faceplanting the sand, dragging for another 5...(by this time I was thinking "I hope this guy knows what he's doing?") He walks back to grab his board and proceeds into the water...
As he was about to get on his board, another small gust hits and launches him (boardless) about 10m away, whilst his board gets washed back into the beach...I (thinking I was still helping) grabbed his board and started walking downwind, where he had been dragged to, and slid his board back to him, nearly getting decapitated by the lines that darted past my head...
I took off back to the ute where the others were watching with fascination...The poor bugger got dragged several times over the next few minutes, (and nearly took out a lady walking her dog on the beach) until common sense kicked in and he obviously decided that he was overpowered...He made it back onto the beach and proceeded to pack up (where he was treated to one last drag along the sand before dumping the kite). He then packed up...
I wandered down a bit later as he was walking up to his car to see if he was OK, all good, and still had a smile on his face, commenting that he underjudged the wind/kite size, and hopefully tomorrow will be a bit lighter, I wished him luck...
My take on the situation was that even if overpowered, you're not in any mortal danger when windsurfing, and not a hazard to others...one good gust and that guy could've been smashed into the cliff-face, or worse, seriously injured other beach users...
This guy seems like a nice enough guy, and good on him for getting out there, but honestly, taking up half a beach and the danger he put himself and others in was a bit ordinary, and worst of all, he missed out on a good sesh
