Para U should rake in alot of comment on this one!!!
The rule - as long as you have power from the kite you have control. Cross on-shore - straight onshore and it can be a bugger to get off the beach.
1) The Hot zone is the wave zone
Choose a zone you are confident with i.e.no big dumping sets coming in - U are capable of pulling a U-ee - zig - zag along in the white water till you see your slot. Go out well beyond the break and have a cruise - try using the green water waves as ramps or if running with them practise your zig-zags.
2) Going across the hot zone on the way out and the way in
As mentioned in previous post going out into white water there is nearly always a lip - You need to help you board ride over it - weight on the back - remember that power as you often turn to go straight at the wave and edge hard up wind killing your power -
When you are coming in for the first few times ride in along the back of a wave and get used to positioning yourself. Do not overtake a breaking wave unless small.
3) Choosing your moment on when to start playing in / on the waves. If U R on a TT then make sure your bottom turn back towards the wave does not bury the nose

- so run long then turn back.
4) At least enough wind to get a quick re-launch and hopefully not having to sine your kite too much. Until you get used to it, going out, U can find you loose an edge going over a wave with any speed,

barrel towards the kite take a flier on the next lip and crash

- keep your knees bent going into the wave - imagine trying to keep your head at a constant height - you absorb the lift from the wave by bending your knees - it is easier to keep your edge. = second nature before long

.
Through all of this keep a firm image of where you kite is - as long as you have power you are ok - the trouble happens when you are in breaking waves with the kite down - if this happens - ditch the kite quick if you have no line tension.
Downwinders are great fun - my first few I stressed up going through the wave zone had a ball out to sea then stressed up coming back in thru' the waves.

On an empty beach the white wash zone can be plenty of fun for a down winder too - but any flags - you need to go out (or walk past).
Using a directional - requires a bit more effort but way to go in the longer term I reckon. Suggest watching your local crew.
Bugger growing a set - opening another chapter IMO
