step one: the kite dropped. it is lying fronttube down, exactly downwind of ya and pulling downwind like a sail. this is where we start.
step two: flipping the kite:
now you grab the depower-lines,
give them a hard pull and then release. the kite is pulled towards you and then has suddenly the possibility to travel downwind again. this will cause him to flip on its back. tips facing skyward.
step three: getting it to one side:
now, the kite lying like this, you pull one of the brakelines (located left and right @ the bar) for about 2m.
when the kite is lying there, you can see how it reacts - if nothing happens, try the other line. the kite now starts to travel into starting position. don't swim against it, just let yourself float. when the kite reaches 90° to the wind, one of the tips will rise on its own and the kite will start.
sometimes it may happen that the kite wants to start earlier - this mostly leads directly to step 1 ... if it's @ 90° to the wind, it will just rise sideways like it does when the guy at the beach helps you starting.
ok

this should work in 3-4bft
