Kitesurfing kiteboarding equipment

In order to kitesurf, several pieces of basic kiteboarding equipment (or called kitesurfing equipment) are needed. These are detailed in the following sections.
 
Power kites
 
A power kite is available in two major forms: leading edge inflatables and foil kites.
 
Leading edge inflatables
 
Leading edge inflatable kites, known also as inflatables, LEI kites or C-shaped kites, are typically made from ripstop nylon with inflatable plastic bladders.The inflated bladders give the kite its shape and also keep the kite floating once dropped in the water. LEIs are the most popular choice among most kitesurfers thanks to their quicker and more direct response to the rider's inputs, easy relaunchability once crashed into the water, and resillient nature. If an LEI kite hits the water/ground too hard or is subjected on water to substantial wave activity, bladders can burst or it can be torn apart.
 
In 2005 Bow kites (also known as flat LEI kites) were developed with features including a concave trailing edge, a shallower arc in planform, and frequently a bridle along the leading edge. These features allow the kite's angle of attack to be altered more and thus adjust the amount and range of power being generated to a much greater degree than previous LEIs. These kites can be fully depowered, which is a significant safety feature. The ability to adjust the angle of attack also makes them easier to relaunch when lying front first on the water. Bow kites are popular with riders from beginner to advanced. Most LEI kite manufacturers developed a variation of the bow kite by 2006.
 
However, early bow kites have the following disadvantages compared to classic LEI kites:
They can get inverted and not fly properly
They are a bit twitchy and not as stable
Heavier bar pressure makes them more tiring to fly
More difficult to relaunch
Lack of "sled boosting" effect when jumping
In 2006 second generation flat LEI kites were developed which combine 100% depower and easy, safe relaunch with higher performance, no performance penalties and reduced bar pressure. These kites are suitable for both beginners and experts.
 
Foil kites
 
Foil kites are also mostly fabric (ripstop nylon) with air pockets (air cells) to provide it with lift and a fixed bridle to maintain the kite's arc-shape, similar to a paraglider. Foil kites are designed with either an open or closed cell configuration; open cell foils rely on a constant airflow against the inlet valves to stay inflated, but are generally impossible to relaunch if they hit the water, since they have no means of avoiding deflation, and quickly become soaked.
 
Closed cell foils are almost identical to open cell foils except they are equipped with inlet valves to hold air in the chambers, thus keeping the kite inflated (or, at least, making the deflation extremely slow) even once in the water. Water relaunches with closed cell foil kites are simpler; a steady tug on the power lines typically allows them to take off again.
 
Foil kites are more popular for land or snow, where getting the kite wet is not a factor. A depowerable foil kite can cover about the same wind range as two traditional C-shape LEI kite sizes, so the rider can use a smaller kite, giving a wider depower range, although the new LEI "bow" kites have a comparable wide range. Foil kites have the advantage of not needing to have bladders manually inflated, a process which, with a LEI, can take up to ten minutes.
 
Kite sizes
 
Kites come in various sizes ranging from .7 square meters to 21 square meters, or even larger. In general, the larger the surface area, the more power the kite has, although kite power is also directly linked to speed, and smaller kites can be flown faster; a tapering curve results, where going to a larger kite to reach lower wind ranges becomes futile at a wind speed of around eight knots. Kites come in a variety of designs. Some kites are more rectangular in shape; others have more tapered ends; each design determines the kites flying characteristics. 'Aspect ratio' is the ratio of span to length. Wider shorter (ribbon-like) kites have less drag because the wing-tip vortices are smaller. High aspect ratios (ribbon-like kites) develop more power in lower wind speeds.
 
Seasoned kiteboarders will likely have 3 or more kite sizes which are needed to accommodate various wind levels, although bow kites may change this, as they present an enormous wind range; some advanced kiters use only one bow kite. Smaller kites are used by light riders, or in strong wind conditions; larger kites are used by heavier riders or in light wind conditions. Larger and smaller kiteboards have the same effect: with more available power a given rider can ride a smaller board. In general, however, most kiteboarders only need one board and one to three kites.
Kite prices range from $100 (for small kites) to $1700+ USD. Prices generally increase relative to the kite size.
 
Other equipment
 
Flying lines are made of a very strong, technologically advanced material, frequently Dyneema, in order to handle the dynamic load of various riders in unpredictable wind while maintaining a small cross-sectional profile to minimize drag. They come in many different sizes, generally between seven and thirty-three meters, although shorter and longer lines are not unheard of; experimentation with different line lengths is common in kiteboarding. The lines attach the rider's control bar to the kite at its edges or through the bridle. Most power kites use a 3, 4 or 5-line configuration. The 5th line is used to aid in water re-launching or adjusting the kite's angle of attack.
 
The control bar is a solid metal or composite bar which attaches to the kite via the lines. The rider holds on to this bar and controls the kite by pulling at its ends, causing the kite to rotate clockwise or counter-clockwise like a bicycle. Typically a chicken loop from the control bar is attached to a latch or hook on a spreader bar on the rider's harness. Most bars also provide a quick-release safety-system and a control strap to adjust the kite's angle of attack. While kite control bars are made intentionally light, they must also be very strong, and so are usually heavier than water; "bar floats" made of foam are generally fixed to the lines right above the harness to keep the bar from sinking if lost in the water.
 
A kite harness comes in seat (with leg loops), waist or vest types. The harness together with a spreader bar attaches the rider to the control bar. By hooking in, the harness takes most of the strain of the kite's pull off of the rider's arms, and spreads it across a portion of his body. This allows the rider to do jumps and other tricks while remaining attached to the kite via the control bar. Waist harnesses are by far the most popular harnesses among advanced riders, although seat harnesses make it possible to kitesurf with less effort from the rider and vest harnesses provide both flotation and impact protection. Kite harnesses look very, very similar to windsurfing or sailboarding harnesses, but are actually much different; usually a windsurfing harness used for kiteboarding will break very quickly, leading to unpredictable results including possible injury or gear loss.
 
Kiteboard, a small composite, wooden, or foam board. There are now several types of kiteboards: directional surf-style boards, wakeboard-style boards, hybrids which can go in either direction but are built to operate better in one of them, and skim-type boards. Some riders also use standard surfboards, or even longboards, although without footstraps much of the high-jump capability of a kite is lost. Twintip boards are the easiest to learn on and are by far the most popular. The boards generally come with sandle-type footstraps that allow the rider to attach and detach from the board easily; this is required for doing board-off tricks and jumps. Kiteboards come in various shapes and sizes to suit the rider's skill level, riding style, wind and water conditions.
A wetsuit is often worn by kitesurfers, except in very warm conditions with light winds. When kitesurfing in strong winds, body heat loss is reduced by wearing a wetsuit appropriate for the conditions. A "shortie" is worn to protect the torso only, and a full suit is used for protection against cool conditions, from marine life such as jellyfish, and also from abrasions if the rider is dragged by the kite. Dry suits are also used to kitesurf in cold conditions in winter.
A safety hook knife is widely considered required equipment. The corrosion resistant stainless-steel blade is partially protected by a curved plastic hook. It can be used to cut entangled or snagged kite lines, or to release the kite if the safety release system fails. Some kitesurfing harnesses are equipped with a small pocket for the knife.
 
A helmet is often worn by kitesurfers to protect the head from blunt trauma(the same kind of wakeboarding gear). Helmets prevent head lacerations, and can also reduce the severity of impact injuries to the head, as well as compression injuries to the neck and spine. Maintaining consciousness after a head injury can also reduce exposure further injury.
A personal flotation device or PFD may be required if the kitesurfer is using a boat or personal water craft for support. It is also recommended for kitesurfing in deep water in case the kitesurfer becomes disabled and must wait for rescue.
 
A board leash that attaches the board to the kitesurfer's leg or harness is used by some riders. However, many kitesurfing schools discourage the use of board leashes due to the risk of recoil, where the leash can yank the board to impact the rider, which can result in serious injury or even death. Generally, kitesurfers that use a board leash will also wear a helmet to help protect against this.
 
Signaling devices are useful if the kitesurfer needs to be rescued. This may be as simple as a whistle attached to the knife, or retro-reflective tape applied to the helmet. Some kitesurfers carry a mobile phone or two-way radio in a waterproof pouch to use in an emergency.
 
A buddy is important to help with launching and retrieving the kite, and to assist in an emergency.
 
A GPS can be used to measure distance travelled, tracks and speed during a session.
