and to be sure, a solid post is better than a dog leash sand anchor...
...had to rescue a kite trailing one of those last month!

Set it at the edge of the wind window, on its wing tip.
The kite bounced there once or twice, then started up towards 12.
The kite was at the edge of the wind window and pretty light winds, so not too much pull on the cord.



My take on this :
The problem was the kite launched itself without your command

Side shore wind that day...... may have had a bit of side side off in it at times

@15mph = @ 13knots....... maybe it was a bit stronger than that in reality

If the wind direction fluctuated a bit...... you may not have been at the edge of window at all

Kites do not bounce like that unless the wind hits the inside of the kite at a good angle

For a kite to self launch like that means you had the kite too downwind in the window at not at edge

Could be a combination of kite position plus a gust and a wind shift

Side shore winds do not always follow a straight line...they tend to vary in direction...so beware

Double check all your angles of when you set kite on wingtip

Stay about 20-30 seconds 3 feet from the kite and watch it's behavior

Do some position adjustment if required...find the sweet spot

You should never have to rush going back to your bar and launch

Enjoy your future perfect launches

Very interesting suggestion BWD....that is something to think about, if indeed it lowers or eliminates the risk of the kite launching itself. Hmm.

I agree, a slight angle change in the wind, and a calm self launch could quickly become an out of control hot launch. I had a close call kitemare along these lines, attempting to self launch a 6m in gusty winds up to 30kts. I didn't notice wind had shifted SE to NE while rigging. Meaning when I turned the kite to get it into launch position, I wasn't at the edge of the window any more but directly downwind.....and it threw me on my back so fast I didn't know what hit me. Right beside a big riprap breakwall with an 8' drop. I got lucky....bruised hip, bruised ego, no substantial damage to kite or body, but could have been way worse. Lesson learned....double check wind direction before you pick the kite up for your self launch!

[and emphasizing what everyone says, the most dangerous time in learning to kite is at the advanced beginner stage, when you are over-confident that you have things under control and don't yet fully understand just how haywire things can get! :o ]

lowers

maybe, not eliminates.
Risk is always there.
Wind has to be stable, or risk goes up!

Yes, and the wind at Mohave is seldom Stable ; that is why i went
with a modified version of the self-launch.

Use my bumper on the Van for cord to the chicken-loop.
Set a slightly longer cord to the safety, (both with a snap-shackle) to release.

Pull up the kite so i can look at my own lines.
if the wind is stable and the kite just Sits there i run back to the bar.
If the wind is NOT stable, then i ask a passer-by to please
hold this, (the LE of my kite) to keep it stable while i run back to my bar.

Soon as i get the bar in my hand and have control of the kite i :
A) if it's a kiter holding the kite, i hook in and signal for a release.
B) if it's someone i don't know, i signal for a release and fly the kite
up over there head BEFORE i hook in.

I hook into the safty Last, so if i hit my QR, the safty to the van bumber
is still engaged, (keeps me from getting Drug face-first over the beach.

If it's Too sandy to have my van present, then a duffel-bag of sand or
rocks will suffice for the van bumper.

100% success-rate with this system ; i've even had Good kiters launch me with a
back-line wrapped around the tip of the kite ; this ilimates that possibility !!!

BTW -- Mohave is Still CLOSED ; so i got Plenty of time to make new posts.

I always find the edge of the window with the kite, then pull it a little into it so the bottom wing tip is slightly downwind and the top is leaning over a touch.

In heavy winds and or gusty winds the kite can bounce about a bit.

One bloke on the Aussie forum came up with an idea where he also puts a sand peg into the sand With the hook lying above and securing the bottom steering line. I use this now when it is really howling.

I have seen this to go pear shaped and do exactly what happened to you so you re not alone.

Also running your hand along the front lines as you walk towards the bar as mentioned is something I employ now.

this is not an "interesting" or unique situation. this is extremely common. a lot of people use a tethered launch, everyday. a kite bouncing and either snagging a bridle or steering line on the wingtip, or an outside line under or around the bar end happens all the time.

this is why you maintain contact with a centerline as you hustle from the kite to the bar, so that you can hold the centerline and manually disable the kite as it starts taking off because of whatever issue.

it is not difficult, you will not shred your hand. you need to hold the line and hustle back in the direction of the bar and or upwind only 10 of 15 feet to flag out and disable the kite. the low centerline will bring the kite down the cleanest and fastest with the least distance traveled by you. people like the high centerline because they think a little tension on it helps prevent the kite from bouncing. low centerline is recommended for faster cleaner disabling of the kite.


large objects (and small pointy screwy anchors) have all been hucked through the air at kiters and others, kites have gone drifting downwind dragging bars through others, many times.

maintain contact with a line so that you are prepared to disable your kite when things happen, so things dont happen.

That was Easy on the 2008 Ozone Edge, with it's center 5th-line ; my 2010
Edge doesn't have that 5'th-line . :(
