... yeah cut the 5th, thats helpful ... anyway on with my take on the self launch!
Since we have big tides and huge beaches, to self launch near the water can involve a 500m walk, so were all usually spread out and do it on our own. All of us self launch and are fairly good born out of necessecity. The day I saw my 13 yro son, self launch in 20 knots, and did it safely with ease was a great day for me and if a teenager can do it, every one can!
The two ways is running lines upwind or downwind of the kite when its sitting on the beach. For no other reason but just because, I started running my lines upwind and usually that way all the time, I run my lines upwind. When I was teaching myself, I figured that the bar ends up the right way when you grab it, as opposed to upsidedown whe you run your lines downwind.
1: Put kite down in an area where you have room for it to slide incase something goes wrong and make sure there are no sticks/rocks etc so if it does slide the leading edge doesn't get damaged or get caught up with someone/something else.
2: I usually put board on kite, fins up and if windy, put sand on also.
3: Run lines exactly upwind and connect to kite.
4: When ready, go to kite, pick up board, remove sand and pick it up on the leading edge right at the middle.
5. Lift up kite, don't flip over or anything, just pick it up and walk it upwind til you get to the Y point, then walk 45 degrees towards the way you want the kite to go ie kite towards the water usually. The idea is to get the line free from the kite so if it does slide, your lines can't catch on anything.
6. Put kite down and turn it slightly toward water then run to bar with your board and get the safety on, throwing board down so now its out of the way.
7. Walk around and away from your kite til you can see its underneath, until your 90 degrees from it and the wind direction.
8. Walk backwards away from kite slowly with your top hand on the bar (if the kite is on your right, your left hand will be on the bar to steer it up, or if your kite is on your left then your right hand will be the one to steer it up). Walking backward till your lines start to tighten and you see the kite move. Keep holding the bar, and keep walking backwards slowly.
9. As the kite starts to catch wind, you walk slowly backwards and slowly upwind. If you imagine, the kite sliding in an arc, you do the opposite, as if your the one sliding, but your walking upwind and around. The amount of upwind walking you do is also dependant on wind strength, the lighter the wind, the further up wind you'll need to be for the kite to roll over. By doing the walking upwind and backwards you sort of keep the kite in one spot pivoting at that point so you mimimize the sliding kite.
10. The kite may slide into position but timed well with experience you can get it to stay put. When the kite gets to its balanced point it will want to roll over and now be on its edge and ready to steer up. Strong wind will do it sooner and quickly so watch out. Have your other hand ready to punch out!
Important note: don't do too fast in stronger winds, it can roll over and if too agressive, slide too far and hot launch and even worse, catch an edge, loop and really make it a bad day. Steady is the key! More wind means go slower!
Important note 2: remind yourself where the safety is and be ready to punch out, just incase you stuff up and need to let go.
11: You may have to walk downwind a little depending upon how fast you've done the roll over, but once rolled over slowly steer up to sky. Don't try to steer too fast as the canopy may scrap the ground and damage kite, slow and steady till you get really familiar.
12: Grab board and have fun!
Hope this helps

Good luck and have fun.
cheers,
