1. Different Types Of Kiteboarding Kites
Any traction kite (large controllable kites that can generate pull while it is flying) can be used in kitesurfing. However, there are a couple of issues that make a certain type of kites more desirable for kitesurfing:
- Relauncheability: it is desirable to have a kite that the kitesurfer can relaunch from the water after a fall.
- High Performance: It is desirable to have a high-performance kite that could facilitate jumping and upwind sailing.
- Power control: It is desirable to be able to control the power of the kite dynamically on the water. The ability to control the power and the degree of control means a wider wind range for the kite and a safer kite.
There are a number of kites on the market for kitesurfing. All of them have a certain degree of water relaunch-ability. There are mainly three types of kitesurfing kites:
- Inflatable kites
- Flat Inflatable kites (Bow kites)
- Framed single skin kites
- Ram air foil kites
2005 KiteLoose Patriot.
The Legaignoux brothers, the original founders of Wipika are the inventor of the inflatable kites and has licensed the technology to many other manufacturers. All inflatable manufacturers continue to develop and market their own version of the kite. The patent was filed in 1984 so it has been expired. Due to the permanent “intrusive” shape of the kite (to facilitate water relaunching), the kite is always “powered up” even on the water. One needs a good working safety release system when using this kite.
There are generally two types of inflatable kites, 2 line, and 4 line inflatables. The advantages of 2 line are ease of use and stability. The advantage of a 4 line inflatable is higher performance and better power control (by changing the Angle Of Attack or AOA of the kite).
Due to many good characteristics, excellent wind range, ease of jump, and wide range of choices, inflatable kites have more or less dominated the kitesurfing market and made major in-road to the kite snowboarding and kite skiing market with the introduction of the 5th line to facilitate relaunching on snow.
Flat Inflatable Kites (Bow Kites)

A more detailed discussion of the flat inflatable kites can be found at Flat LEI Kites
The major advantages of a flat inflatable over the standard inflatable kites are:
- Flat inflatable kites can be fully depowered
- Flat inflatable kites have a larger wind range
- Flat inflatable kites can relaunch easier
With such advantages, flat inflatables replaced the standard inflatable kites as the dominant kitesurfing kite in 2006.
Framed Single Skin Kites
Framed Kiteski kite.
These types of kites have a leading edge made of fiberglass or graphite, one main batten in the center, and a number of thin battens along the chord to give the kites a permanent shape. Similar to windsurfing, it will take quite a bit of practice to learn how to water launch a 2 line skin kite (with the help of a 2 line reel bar).
Once one gets the hang of it, these kites are probably the most dependable kites for water relaunching. The only time one may not be able to relaunch these kites is when the wind is light (less than 8-10 knots). KiteSki was the inventor of the launchable 2 line skin kite system. KiteSki used to have Banshee manufactured the kites. Both KiteSki and Banshee developed and marketed their own version (which could be very different).
After a fall, a framed single-skin kite stays flat on the water; therefore, a safety release system may not be needed. However, it is wise to have a safety release system to easily retrieve the kite and the control bar (the kite and the control bar may fly a fairly long distance downwind before landing on the water).
For some reason, framed single kites got less and less popular among the kitesurfers, and rarely one see any kitesurfer using these kites anymore.
Ram Air Foil Kites
These kiteboarding kites have no rigid structure. The shape of the kite is formed while flying. It has shapes similar to airplane wings and therefore, probably, are the most aerodynamic kites. Ram air kites have been on the market for a long time and have been used by many.
In the early days of kitesurfing, Concept Air and F-One released the first water launchable ram air kites, the Concept Air EX’s Wave, and the FOne ATK kites. These kites normally have a limited number of air intakes and a valve system to prevent the air to escape after a fall. Due to these characteristics, these types of kites are also called closed cell foil kites.
Concept Air was the first company to introduce a foil kite incorporating a system allowing the kitesurfer to control the power of the kite by pulling on the third line to change the shape of the kite (therefore changing the camber/projected surface of the kite). Since then, many other companies (ConceptAir, Flysurfer, Boom Vector, Ozone, etc.) have introduced foils with systems that use AOA to control the power of the kite similar to the inflatable.
Peter Lynn has also introduced a new type of foil kite called the Arc. The Arc is mainly a closed cell ram-air with the sled shape of an inflatable. Similar to a 4 line, an Arc kite can also be depowered by pulling on its front lines to change the angle of attack.
Kite Wind Range
Different wind conditions require different kite sizes. Since different kites have different aerodynamic. Your kite vendor should be able to provide a table recommending the wind range for a certain kite size.
How much wind range is needed for a kite?
Due to the ability to depower the kite, kites’ wind ranges are very large (usually double the wind speed, for example: from 10 to 20 knots wind range). One normally only needs 2 or 3 kites to cover most winds encountered at any location.
Kite Size Chart (Flat And Inflatable LEI)
- A flat-surface 12m2 LEI (or from 10m2 to 14 m2 LEI) is a “standard” size that almost everyone should have. This is the size that would accommodate all riders with the average win range we have on this planet. So get a 12m2 LEI and ride with it for while then you will know which size you will need next for lighter wind and stronger wind (a rider normally needs 2 or 3 kites).
- The difference between your two consecutive LEI kites should be around 3 m2 or 4 m2. For example, 9 m2, 12 m2 and 16 m2 LEI would form a very good kite quiver
- A 10 m2 Flat LEI is roughly equivalent to a 12 m2 LEI (so use this 5/6 factor when comparing a Flat LEI to a traditional LEI.)
- The difference between your 2 consecutive Flat LEI kites should be around 4 m2 or 5m2. For example, a 11m and 16m would form a very good kite quiver.
- A 8 m2 foil is roughly equivalent to a 12 m2 flat surface area inflatable (so use this 8/12 or 2/3 factor when compare foil to inflatable)
- The kite sizes are normally the flat-surface size of the kite (watch out for some vendors who still use some old arcane size indication methods)
- Most foil kite projected surface is normally 90% to 100% of the indicated size.
2. Kite Lines
Line Types For Kiteboarders
- Use either Spectra (Dyneema in Europe) or Kevlar lines. These types of line may stretch only 4% which is much lower compare to the others
- If possible, use floatable lines.
- Use 400 – 500 lb. lines for the main lines (the lines in a 2-line kite or the 2 front lines in a 4-line foil) and 200 lb. for the brake lines (the 2 back lines in a 4-line foil). Please note that there is no brake lines in a 4 line inflatable so use 400 – 500 lb. lines for all the 4 lines.
Kite Line Strength
Line strength used is actually a function of your weight. The lines in a 2-line kite should have a minimum strength equals 2.5 times your weight. For a 4-line foil, the main lines should have a minimum strength equal to 2.5 times your weight while the brake lines should have a minimum strength equal to your weight.
For example, if you weigh 200 lb., you should use at least 500 lb. lines for your 2 line kites and 500 lb. main lines, 200 lb. brake lines for your 4 line foils. For the 4 line inflatable kites, the two back lines should have the same strength as the two front lines.
Appropriate Knots, Sleeves & Splice For Kitesurfers
The knots (2 overhand or figure 8 knots) are tied in that section. These knots will reduce around 30 – 40 % the strength of the lines (this has been tested by Dave Culp, a pioneer kite sailor). If you use knots, just multiply the line strength figures above by a factor of 3/2.
- Put a 30 cm sleeve at the end of a line
- Fold the sleeved portion to form a 15 cm loop.
- Using the very small zigzag pattern, sew the two sleeved lines together (the needle should go through both the sleeve and the line). Only sew 12 cm such that you end up having a small 3 cm loop at the end.
Lines get stretched, so open the wove pushing with your hands.
Thread the end of the line into its own core for about 5 inches.
Milk the line to make it even.
Thread more than 5 inches inside the core once more. Milk again.
Steps 4 and 5 to finish the job (to make a finer job you could slip in the loop some Dacron sleeve before splicing).
To repair a broken kite line
Push one end inside the core of the other end of the line, starting from 10/15 inches below. Repeat the operation with those extra 15 inches you left on the other line. Milk the line to make it even, if the job is done carefully you will hardly notice the repair
Accurate Line Length For Good Kitesurfing
Shorter lines will restrict the wind window (the flight path of a kite) therefore reduce the risk of the kite picking up extreme speed that can generate uncontrollable power. Longer lines will extend the wind window, therefore, increase the kite flight path to enable the kite to gather more speed for more power.
Most use 25m – 30m lines as that will give the most versatile range for starting, going upwind and for jumping; however, be adventurous and try different line length as you may find a length that suit you better than the “standard” 25m – 30m.
3. Kitesurf Control Devices
Control devices allow you to control the kites. Many use a 4 line control bar for a 4 line inflatable and a pair of handles or a 4 line control bar for a 4-line foil. Using the control device, you can pilot the kite to fly anywhere within the wind window. For all its practical purposes, the wind window is basically the area you can see with your eyes (85 degrees to the left, 85 degrees to the right, 85 degrees upward) when you are facing straight downwind.
Inflatable Kite Control Devices
Using a kite control bar that is inflatable (normally with 4 lines, two front lines, and two rear lines), you can turn the kite to the left by pulling the left end of the bar and turn the kite to the right by pulling the right end of the bar. If the bar is in a neutral position, the kite will continue on its current flight path and fly to the edge of the wind window (left, right, upward, or downward edges).
The two rear lines (control lines) of the kites are tied to the leader lines at the ends of the bar and the front lines (power lines) are tied to a central leader line. There is some adjustable strap and/or “chicken loop” set up on the centerline allowing you to shorten it to adjust the length of the front lines .vs. back lines to adjust the angle of attack of the kite (adjust the power of the kite).

Inflatable Depowering System
A 4 line inflatable can be depowered by shorten the front leader line (reduce the AOA) and empowered by lengthening the front leader line (increase the AOA). This shortening and lengthening of the front leader line can be done via a chicken loop or a trim strap. Some even tie the front leader line to their harness (can be released via a quick-release mechanism).
For classic inflatable, some kiters even use a 5th line to help to relaunch the kite and also to be used as a safety system line.
Flat LEI Bar For Depowering

Kite Foil Control Devices
You can turn the kite to the left by pulling on the left brake line and turn the kite to the right by pulling on the right brake line. If both the handles are in a neutral position, the kite will continue on its flight path and fly to the edge of the wind window. You can slow the kite down by pulling slightly on both of the brake lines; stop the kite by pulling harder on both of the brake lines, or make the kite moving backward by pulling very hard on both of the brake lines.
4 line bar & 3 line setup
You can use a 4-line bar to control your foil. The front lines are connected to the center of the bar (or about 20 cm from each other) and the brake lines are connected to both ends of the bar.
If you have a power steering bridle (a line connecting the front bridle to the trailing bridle), you can rig a 3-line set up by connecting your front lines to both ends of the bar and a centerline to the trailing bridle.
Foil Depowering Systems
Foils have a rich set of kite depowering systems:
- Depowering by changing camber: This system allows a kitesurfer to shorten/lengthen the trailing line to increase/decrease the trailing camber of the kite to increase/decrease its power. This system was used by Concept Air New Wave.
- Depowering by neutralizing a section of foil: This system allows a kitesurfer to flatten the middle section of the kite by pulling on a line to decrease the power of the kite. The system was used by Jojo Rage and Windtools Mosquito.
- Depowering by changing AOA: Similar to an inflatable, this system allows a kitesurfer to change the AOA of the foil. This system was used by Arc, Boom Vector, ConceptAir, and Flysurfer.
- Depowering by changing foil/sled shape: This system allows a kitesurfer to change the shape of the kite from a flat foil to a sled and vice and versa.
Kiteboarding Reel Control Bars
There was some other 4 line reel bar that can be used with 4 line inflatable kites. For some reason, reel bars never became popular among kitesurfers.
Safety Systems For Kitesurfers
Regardless of whichever control device you use, make sure that it has a dependable safety release system (especially if you use inflatable kites). This system should be able to disable the kite completely. Once activated, the system should also allow you to retrieve the kite and the control device (so you do not lose your kite).
Make sure you test the safety release system incorporated with your control device in light wind condition before using it (the best place to try this is in shallow water as some kites may crash and break when you activate the safety release system on land).
NEVER USE ANY CONTROL DEVICE WITHOUT A SAFETY RELEASE SYSTEM
You can use a 4 line bar to control your foil. The front lines are connected to the center of the bar (or about 20 cm from each other) and the brake lines are connected to both ends of the bar.
4. Kitesurfing Boards (homemade?)
A beautiful homemade board.
You can use almost anything as a board: skim-board, water skis, wakeboard, windsurfing board, and of course, kiteboard. Generally, it is best to use a kiteboard that is specially made for kitesurfing. A number of years of R&D and experience have been put into designing those kiteboards. You can also make your own kiteboards as specified in the Board Building section.
Bidirectional Kiteboards (twin-tip)
There are mainly two schools of thought in kiteboard design. The first school of thought comes from people with a wakeboarding/snowboarding background. These types of boards are called bidirectional, or twin-tip boards, normally very thin, barely floatable by itself and use straps or bindings attaching the kitesurfers’ feet to the board.
Best Kitesurf Boards For Jumping
These boards are great for jumping and exotic moves in high wind. They are less than ideal for light wind conditions (less than 10 knots) unless the kitesurfer uses a bigger kite. These types of boards are normally 110 cm to 170 cm long and 33 cm to 45 cm wide. Kitesurfers do not change feet when they jibe on these boards. They simply reverse the direction (similar to wakeboarding) or go from a heel-down to a toe-down position when jibing.
Directional Surf Boards
Directional boards from Stonker.
The second school of thought comes from kitesurfers with a surfing or windsurfing background. These directional kiteboards are normally slightly thinner than a regular surfboard, sharper edges, and having 2 or 3-foot straps (similar to a windsurfing board). These types of boards are normally 140 cm to 230 cm long and 35 cm to 50 cm wide.
Best Boards For High Speed
These boards are great for speed and light wind conditions. While they would do well in jumping and exotic moves, they are normally larger and therefore harder to control in extremely high wind conditions. Kitesurfers change feet similar to windsurfing when they jibe on these boards.
Fins and Other Kiteboarding Accessories
All types of boards may have fins or be without it. Even though fins may help to make the board go upwind, all fins are mainly used to keep the board going straight. It is the upwind edge of the board that acts as the real fin providing lift to keep the board going upwind.
2007 Hyperlite Roam, a new finless wakeboard.
Similar to a surfboard, a kiteboard may have a leash attaching the board to one of your feet (or harness). Normally, a high-quality, surfboard-type leash around 6′ long is used as a leash. Since there are a number of board leash-related accidents in the past, most modern kitesurfers abandon board leashes and learn “body drag upwind” to retrieve the board instead. Furthermore, with the new Flat LEI, a kitesurfer can fully depower the kite and swim back to retrieve the kite (body drag upwind is not really needed).
To further discourage the use of a board leash, Ocean Rodeo markets a device called the “Go Joe” which makes a board flow downwind faster therefore easier to be retrieved.
How To Find The Best Kiteboard
|High wind area||Bidirectional (for most riders)||Directional (for special reasons)|
|Most Kitesurfers||40cm shorter than your height|
|Special Cases (wave, etc.)||30cm shorter than your height|
|For Learning||20cm shorter than your height||30 cm longer than your height|
Use the following guidelines for board selection in light wind areas (5 – 15 knots of wind most of the time).
|Light wind area||Bidirectional||Directional|
|1 board||30cm shorter than your height||20cm shorter than your height|
|2 boards||Your height for light wind|
40 cm shorter than your height for stronger wind
|30cm longer than your height for light wind|
30cm shorter than your height for stronger wind
|For Learning||Your height||30cm longer than your height|
Instead of dependent on height, another rule-of-thumb for board selection is that board surface should be proportional to the square root of rider weight (a rider twice as heavy as another should use a board 1.4 times the planning surface).
Best Kiteboard Length and Width
The newer generation of boards is wider and shorter than the traditional boards. To select the appropriate wide board, just make sure that the newer wide board has the same planning surface as the traditional boards (up to certain limits, boards with the same planning surface should accommodate the same wind range).
Best Chubby school/light wind board is around 140cm long.
Going Upwind when Kitesurfing
To go upwind on a free sail system such as a windsurfer, the sailor moves the sail backward to move the center of force behind the center of resistance of the board, fins, and keel.
- Move the center of force backward by transferring his weight more to the back foot.
- More important, move the center of resistance forward by pressing the windward edge to put the board from 15 to 45 degrees to the water.
5. More Kitesurfing Equipment
Compare to other sports such as windsurfing, a kitesurfer has a much more active role when surfing. While a windsurfer only has to trim the sail and steer the board in the desired direction, a kitesurfer has to do the following:
- Constantly move the kite and put it in the proper locations in the wind window to generate power (“trim” the kite).
- Edge the upwind rail of the board to provide lateral resistance to go upwind.
- Act as a “universal join” to transfer the power of the kite to the board to make the board move.
- Steer the board in the desired direction.
This is why going upwind in kitesurfing is much harder than in windsurfing. Any less-than-perfect move in any one of those 4 actions will result in the board moving downwind. For example, if the kite is flying too high in the wind window, it tends to lift the surfer up, therefore, makes it harder to edge the windward rail of the board properly.
Harness And Lifejacket For Kiteboarding
You normally use a harness system (or something equivalent) to attach the control devices directly to your body (to temporarily release the tension on the arms). Any related harness system can be used. In general, normal kitesurfing or windsurfing harness system is also sufficient (a chest, waist, or seat harness).
Since the board cannot float with you sitting on it, a life jacket is always recommended.
Water Shoes, Helmet And Hook Knife
If you surf in moderate or strong wind (15+ knots), you may want to wear a helmet to protect your head. A hockey helmet is sufficient.
You may want to have a hook knife. They are often available at your local skydiving or paragliding store or in some cases, a dicing shop. They are helpful in case of the line tangles with your body. (Photo from Art Dervaes).
