Multi-line power kites first made an appearance way back in the 1970s, when the Flexifoil stunt kite became available for anyone to buy. This kite had a single flexible spar running the full length of its leading edge. The front edge, if you're not quite up with the terminology. This was a fast kite with plenty of power, and people still fly this design today.
Anyway, a small number of people soon started experimenting with the Flexifoil as a traction kite. They found several ways to drag themselves along, for example over sand in a small wheeled buggy.
In fact, these days, kite power is used over
Parafoils are the type most commonly used over dry surfaces.
Check out this dual line parafoil from Amazon which can be considered a trainer kite for extreme kiting in general.
Down at the beach, Leading Edge Inflatables are the most practical since they re-launch easily from water.
The kite in the photo is something different again - a single-line power-sled. So called because large kites of this type have ample lifting strength. All manner of inflatable wind art can be hung off the flying line!

Types Of Power Kites
Over the years, kite designers have made large kites for specific sports, so there's a lot of different types. I'll avoid getting you bogged down or bored to death by just mentioning 2 broad categories...
- power kites
- traction kites
Some people use this name for all 2, 3, 4 or 5 line flexible kites. Many other people, including me, divide these into 2 or 3
line 'power kites' and 4 or 5 line 'traction kites'. There is a big
range of sizes available, and cost depends a lot on size.
Now, are you totally confused about exactly what is a power and what is a traction kite?
What's the real difference? I'll try and sum it up for you.
Power kites are at the smaller and cheaper end, and are used mainly
for stunt flying or just having fun. Yes, they are just another kind of
stunt kite. A small power kite is pretty fast through the air, which is
part of the thrill of flying it! There's one in the photo over there.
if they are 3 square meters (about 30 square feet) or bigger in area,
they pull quite a bit. Naturally, people then think about using them to
pull along small land buggies, for example.
Depending on wind conditions, there's nothing to stop you flying a
4-line traction kite as a rather expensive and impressive stunt kite!
The extra brake
lines let you turn the kite with less arm movement than the 2-line
variety. Also, the brake lines are handy for bringing the kite down onto
the ground with a bit more control.
The beach picture shows a kite surfer in action.
With 4 or more lines dragging through the air, and other aerodynamic
reasons, traction kites are a bit slower than the smaller muli-line kites.
Most surfing kites are not
parafoils. Can see the leading edge spar and a few other shorter spars
helping the kite keep its shape?
Some kite surfers these days are into kite racing around a course, much like a boat race.
it's possible to be self-taught, many people these days sign up for kite
surfing lessons. This way, progress is quicker and important safety
lessons are learned the easy way.
I might just mention here that some
traction kites are built purely for speed, compared to other kites of
the same size. These are 'racing kites', and if you get one, don't
expect it to be as easy to fly as other traction kites!
Power Kites in Action
OK, how do people fly this kind of kite these days? What a big topic! This type being so popular, the manufacturers have managed to cater for just about everyone. Young children can fly the smallest 2-line power kites under supervision while down at the beach. At the other end, top-notch athletes push the limits doing freestyle tricks over snow or in the surf with other kite boarders, using very expensive Leading Edge Inflatables.
The top-end traction kites are more like aircraft than toys. That's not at all surprising when you consider that some parafoil kites used for traction are made by paraglider manufacturers! The cost of these flying wonders can exceed 1000 US dollars.
Mind you, if you are a very patient person, you could save a bundle by making power kites from scratch. Heaps of sewing involved, believe me.
It's wise to have a chat with the experts about what kind of power kiting you'd like to do, before actually laying down your cash for a kite!
"Love the easy to understand step by step instructions, made from next to nothing materials and above all so much fun to fly... cheers Tim for sharing your well thought out pdf kite designs with the whole world. Very satisfying making your own and watching them get air-born for the first time."
"I decided to run kite making as an elective again on this camp in the past week - so I bought all your e-books, a bunch of materials, and then took a group of 10 high school students through making the kites over 4 days. We built a diamond, a Barn Door, a Delta, and two skew delta kites. Again - every single kite flew."
Time for a Big List. I love lists, I'm one of those list-driven types of people. :-) Even if you're not like that, a list is a great way of summarizing information. It struck me that power or traction kites are used in a huge number of ways, so here is the biggest list of power kiting activities you will find on the Internet.
- pure fun, just aimlessly flying a multi-line Parafoil kite as far as possible in all directions
- learning some stunts and practicing them for fun, or competing in kite flying contests
- in a controlled way, letting yourself get dragged across dirt, sand, ice or grass
- breaking silly records, such as in September 1988 when a 43 square meter (460 square feet) parafoil broke the record for the Worlds Largest Stunt Kite
- breaking sports records, such as the C-class unlimited speed sailing record, with a set of catamaran hulls powered by a winch controlled stack of Flexifoils! Cool.
- kite surfing, or getting dragged along while riding a surfboard
- kite surfing while riding a windsurfing board
- kite surfing on a kiteboard
- body surfing powered by a traction kite
- snowkiting, or getting dragged along while riding a snowboard
- kite boarding on a land or all-terrain board
- kite boarding on a mountainboard
- kite sailing a boat on water
- kite sailing a sled on ice
- getting dragged along while riding ice skates, rollerskates or rollerblades
- kite skiing over snow
- kite skiing uphill is now a part of Scottish skiing history!
- riding a kite-powered land kite buggy
- getting dragged along while on water skis
- dangerous: kite jumping, where you let yourself leave the ground for as long as you dare
- even more dangerous: man lifting, where a large tethered traction kite lifts someone high off the ground
'Freestyle' kite-skiing and kite-boarding have both seen big increases in popularity, as well as kitesurfing. Kite landboarding gear has many similarities to the gear used over water and snow.
you have a think about it, it's not hard to make up a few kiting sports
of your own. Here's my little effort, but don't try these at home ;-)
- kitebagging, across wet grass while wearing a large plastic garbage bag (very do-able I'm sure)
- kiteduning, over and around sand dunes on your bare feet, 'getting some air' once in a while (mmm how practical is this..)
- kite-vertising, using your kite as a billboard at public events (not as silly as it sounds)
- kitebiking, using your feet to steer and your hands for the kite (you'd be stupid to try this)
- wet stunting, flying your kite underwater in tidal currents while scuba-diving (I wasn't serious, but then I saw some pics of people actually doing this!)
Think I'll stop before it gets too silly.
As you can see, just about any way of moving across the earth's surface might be tried by a keen traction kiter!
Now here's an interesting application for power kites that doesn't involve any movement across land or sea... Clean energy generation, believe it or not!
Here's a few notes on
which might prove handy, particularly for beginners.
The history of power kites extends back to the 70s. Using big kites to pull you along isn't a new idea!
Check out the big purple kite weaving around in the video below - pulling it's skillful pilot across the sand in a buggy...
Before you can emulate that buggy pilot, you need to get some skills together. This dual-line power kite is a good start. Get the smaller 220 size if you have a smaller build or want to fly in fresh wind. These things pull!
