Had my first shot at trying to self launch my 8m Catalyst today in 23-26kt cross-shore wind, with mixed success.

I attempted the Cabrinha method, where the lines are laid out upwind, the kite moved on top of the lines, connected, then the kite is moved further upwind and to the ocean-side of the lines, turned to face 45 degrees away from the wind. Supposedly then the 'downwind' trailing edge will catch some wind. The lines will then be sticking straight out the back of the kite, going downwind before they loop back around the kite, then upwind to the control bar.

The next step calls for the launcher to connect to the bar as per usual and walk upwind. This then is supposed to rotate the kite to catch more wind, then it is meant to pivot up onto its tip and launch like a water relaunch.

The video on the Ozone website from 2008 shows something similar, but much more vague.




So that's what I tried. In reality, when I turned the kite 45 degrees away from the wind in order for the trailing edge to catch wind, the centre strut got blown over the downwind trailing edge, pinning it down, and it didn't really catch anything. It kind of did a contortionist thing and didn't want to play nice. Trying to pivot the kite by tensioning the lines only further pretzeled the kite. I got a bit too scared by that point to push it any further because I didn't want it to suddenly hot-launch. It just looked way too weird and unsettling.

The videos are not particularly clear on where exactly you should be for the launch. Is it telling me to be directly upwind from the kite when I tension the lines and pivot the kite? If that's the case, isn't the kite going to launch from the power zone?



Is there any easier way to self-launch? I know about the sandbag/sandscrew method (have not tried it yet), but I was wondering if there was any other method or if I should stick with practicing the Cabrinha method. The beach I normally go to has a fairly narrow launch zone, even at low tide (if that makes a difference).

Thats BurkeyBoy, I will give it a shot tomorrow morning.

When you say 'pull the far wingtip towards you', could you elaborate a little further? Is it something I actively have to do, or will this happen just by keeping the lines tensioned and walking in an arc?

Also, I have never lain out lines downwind from the kite, but I understand that I have to reverse the bar position when laying out the lines then remember to reverse it back again for launch?

The Cabrinha video clearly states it considers this a manouvre for advanced kiters - not beginners or intermediates. So their video is not going into detail for beginners to use the method.

Once a kiter gets the hang of it and has done it a few times, its not difficult to do - if it all goes well. There are many things that can and do go wrong though, and that is where the problem lies with inexperienced people using the method.

Not pumping the kite up enough, sand jamming a pulley, a line snagging on something small jutting out of the sand, wrong connection of lines, bridle snagging on a wingtip, gust moving the kite before you are ready, having your bar the wrong way up, not tensioning the lines right, being at the wrong angle to the wind - are just some of the things a beginner can do wrong.
It also tends to wear the leading edge of your kite and may cause punctures as the kite slides on the beach.

I think its better to use the anchor launch method with a heavy bag full of sand - especially as your beach sounds like you dont have a safe distance clear downwind.

Cheers thanks for all the help.

As you arc around and move upwind slightly the kite will turn towards you automatically. I tend to pull a bit more on the far wingtip (backhand line) so it pivots more and therefore is less likely to slide downwind too much before filling.
Yes, you do have to lay out the bar reversed. Left is usually red so that lays on your right as you are looking upwind to the kite. As you go to launch you'll see quite simply how to switch the handle position.
I've tried anchors and plenty of sand etc, this is so simple once you've done it a few times, just make sure the lines are stretched out with some tension as you arc around and launch. That way, there's less chance of catching lines on a pulley or knot or something. I once had a disaster when I changed a bridle line with some heavier line. The knot was too big and my back line snagged on it. When I launched the kite started looping very quickly. I should have just pulled the safety. Long story short, kite in a tree. This happened cos' back then I never used to arc around with lines tense, just walk a bit out wide and up wind and then launch. This obviously allows the lines to drag over each other when launching.
Hope this makes sense.

I never self launch. Always get help.



And twos better than one

Setting up your bar downwind and slowly walking upwind with tension in your lines (as Steve has described) is the only way to go, especially when you are self launching.

Do this. The kite should turn and fill with air, sitting at the edge of the window, ready to launch.

Catalyst is an easy to self-launch kite.

There is also a clever launch technique for LIGHT wind only:

Can't wait to give all these great tips a go... now I just need wind

If the beach is quite narrow and I cant do a full arc without either wading into the water or walking up onto the dune vegetation, which would be preferable from a safety standpoint (not from an environmental standpoint... people seem to get a little hurt when they see others walking on dune vegetation)?

I know that launching towards the water is normally the method in case you get dragged, but the issue of lines tangling in the plants might warrant wading into the water? If I get far enough into the water for the launch it wouldn't really matter if I did end up getting dragged if something goes wrong (as long as I stop before making landfall)

Easiest way I've found to self launch is to set up the lines so the bar is downwind of the kite, hook in and step backwards to tension the lines. Slowly move in a sweeping motion (an arc)to the side of the kite but keeping some tension on the lines. As you slowly move upwind of the kite and pull the far wingtip towards you, the kite will fill with wind and slide downwind a bit before rolling onto the side and launching. If the wind isn't too strong the kite will sit on the side for a moment and you can check if your lines are clear before launching.

I use this same method and it works well everytime. As previously mentioned self launching and self landing is NOT for beginners.

When learning it always have an experienced kiter supervise you and wait till you've got at least half a good season under your belt.

It's very easy for the kite to roll over and fly low all the way to the edge of the opposite window, which would most likely wreck your kite and yourself.

Always make sure no one is within 100m of you and never try in gusty conditions close to trees, dunes or any other structures.
