Who hasn't been down to a beach and noticed board-riders being drawn along by large surfing kites? Now, it's not just seagulls and swimmers that are a common sight at beaches. A large proportion of the explosion in extreme sports after the year 2000 is the kite-surfing crowd!
This is just a very quick introduction to the kites used by these surfer dudes. This is, after all, a Kite Site, so I'm choosing to focus on the engine of this sport rather than the sport itself.
My family saw quite a bit of kite surfing action in a short space of time in 2007, at the Adelaide International Kite Festival. The breeze was howling, and the surfers were loving it! Whitecaps on the ocean, and board riders getting airborne all over the place. We watched from the jetty in Semaphore.
Are you curious about these big made-for-water traction kites? If so, and if you haven't had the chance to chat about them with a kite-surfer, here's an introduction to the 4 main categories being flown today.
Also, a special focus on one of the most popular surfing kites within each category. For the popularity info, I relied on some enthusiastic members of a big Australian water-sports forum. That's not a world-wide survey, but I'm hoping their opinions aren't radically different from the rest of the kite surfing world!
It's obvious isn't it? A big 'C' shape on the end of those long lines! These were the first surfing kites, and they were designed to float if they came down in water. A pretty essential feature for a kite used in the ocean, and achieved by means of an inflatable spar running along the leading edge. That's the front edge of the kite. Hence these kites are also known as Leading Edge Inflatables, or LEIs which is less of a mouthful. These kites were also designed to be easily re-launched from the water if necessary. On some designs, there are shorter vertical spars which are inflatable too. Actually, it seems surfers talk about 'struts' rather than 'spars', so we'll use that word from here on!
Why are LEI surfing kites still being used when at least 3 other types have since been developed? One reason is that they respond in a quick and direct way to control inputs from the board rider. Perhaps the biggest reason is just that they are fairly simple! Everyone likes a kite that just keeps on going with a minimum of wear, tear and other failures.
I asked around in the forum about which kites appeared to be the most popular. Overwhelmingly, in the C Kite category, the choice was...The Slingshot Fuel.
Now for some basic facts on this design.
On that last point, the size is selected according the combination of surfer weight plus the expected wind strengths. Big surfers need bigger kites, and riding in lighter winds requires bigger kites too. To cover the full range of weather conditions, a keen rider might have a 'quiver' of 3 surfing kites. The Naish Torch also got some mentions in this category.
A training kite like the HQ Hydra Series 300 from Amazon is the way to go for those just starting out. With more experience, the higher-end kites provide more performance and satisfaction.
The Bows were the next generation to come out, and their big selling point was the fact they could handle much bigger wind ranges than the LEIs. They were de-powerable, meaning that the rider could alter the kite's angle of attack to the wind, to a large degree. Never mind the aerodynamics, the bottom line is that the pull generated by the kite can be easily reduced, while keeping the kite in the same area of sky. One thing that made this possible was the flatter curve of these kites, compared to the deeper C shape of the LEI. Another practical result of this was that you didn't need 2 or more surfing kites to cover all wind conditions!
However, there were a few downsides to the early Bow kites. They tended to be a bit harder to fly than the LEI, and pulled more heavily on the rider's arms as well. Hence they could be fairly tiring to fly, particularly in strong wind. Finally, if a Bow hit the water it could be trickier to re-launch than the equivalent LEI.
And which one was our forum kite surfers' favorite?
The Cabrinha Crossbow. Again, here's a few basic facts...
The BEST Waroo also got plenty of votes, followed by the Ozone Instinct.
By 2006, kite designers really excelled in striving for the best of both worlds. They managed to combine the easy re-launching characteristics and moderate bar pressures of the original C kites with the 100% de-power ability and higher performance of the early flat LEI kites. Hence the term Hybrid, which just refers to the combining of 2 things together. Kite design in this case.
A noticeable feature of these Hybrid surfing kites is the Supported Leading Edge or SLE, where a series of bridle lines attach to various points across the kite's leading edge. Hence many riders refer to these kites as SLEs. The handling of these kites has been developed to the point where even beginners can soon master the required flying skills.
Apparently there's a lot of these SLEs around now, but in March 2008 the forum poll showed up a clear favorite...The Slingshot REV.
A few facts about this one...
Other Hybrids that got a few mentions were the Flexifoil Atom and North Rebel designs.
It's worth mentioning here that a typical new inflatable kite of any type comes with the following items:
The parafoil kite, or just foil as many abbreviate it, is much different to the other 3 types already mentioned. This type is much like a parachute, in that it is completely flexible and relies on many bridle lines to hold its C shape in the air. Like most land-based kites these days, rip-stop nylon is the usual sail fabric. These surfing kites have upper and lower surfaces, with ribs sewn in between to form cells. When in flight, air pressure inflates the cells, giving the kite a wing-like shape that generates lift. Just like an aircraft wing.
What about when one of these kites hits the water? The designers have taken care of kite-surfers here by providing an extra feature. Inlet valves! Air can force its way in while the kite is flying, but otherwise the valves stay shut, keeping the kite inflated. Hence, it doesn't sink once it hits the water, and can be re-launched fairly easily. Parafoils designed for water in this way are known as closed cell foils.
Since you don't need a pump to inflate a foil, these are also known as self-inflatable kites. The latest surfing kites of this type have wide de-power ranges, just like Bows or SLEs. Hence they can be flown in a wide range of wind conditions.
It seems that not all the guys in the forum like parafoils, but among those who don't mind them, one design stands out....The Flysurfer Pulse 2.
A few basic facts about this kite...
Honorable mentions must also go to the Peter Lynn Venom, Flexifoil Blade III and the Flysurfer Speed in this category!
This has been just a glimpse into the world of surfing kites, from the perspective of a non-surfer. It's a snapshot of the surfing kites being used by Australian riders in 2008. If you knew nothing when you arrived on this page, I hope you now have at least some appreciation for these specialized power kites!
