Read my first post and noticed my mistake in saying lay the lines upwind of the kite I actualy mean downwind and the bar upside down when doing so.....another blonde moment!

I am presuming you do this with no sand on the kite and with the tips facing up. Is this correct?
Na, you have normal sand on the kite as you would to keep it from having the leading edge lip picked up by wind. It's exactly like u would normally lay a kite on the beach into the wind with sand on top to prevent it from being grabbed by a gust, and then lay the lines out the back as mentioned above. The sand will fall off as the kite pops up. Obviously if you're trying this first time in light winds then you might not normally put sand on the kite so don't...
I haven't seen a sonic kite but if it's similar as my bows can't see why it would be any different. The technique sounds and may even look dodgy the first time, but give it a go in light winds a few times. one aspect of this launch is you don't need allot of beach to launch especially if its a slight onshore wind because u are effectively launching within the narrow beach width ninety degrees from the wind direction. Keep in mind at first the kite might drift to one side until you get your angle right so the beach shouldnt have obstacles for a kite to become damaged on.
here's pretty much an animated image link that is the method I use

doesnt look like he had that much room for his launch....
Here is another one from kitepowers video section, again this is a sim method I use ,but he is laying the lines upwind of his kite and moving his kite instead of hooking in and moving the bar across from downwind.
www.kitepower.com.au/blogs/newsYour not trying to launch a bucket *sniggers* like the C kites

, One final point is to make sure your chicken loop is the right side up when hooking in if your laying the bar downwind and hence its upside down, this is so the donkey dick is correctly locked in the chicken loop.. Seen a c kite normal side launch go wrong once because of that - This dude was lucky not to become impaled on a pine post

let us know how you go - best of luck
