F.A.Q. (Frequently Asked Questions)

Updated the Friday 10 May 2013

These are some of the most commonly asked questions...
and their answers !

 How should I attach the risers to the Kortel harness? Blocks to the outer or inner side?

The pullies must face outwards, so as to avoid the speed lines rubbing on the harness. This will also orientate the risers in the most aerodynamic way.

 The SaK looks cool, but it’s a little bit difficult to attach it to the harness with gloves, in windy and cold conditions. Couldn’t you make a more simple system?

Mmm, but why attach it at take off, when you can do it in the warmth and comfort of your living room? The SaK is a reversible bag/airbag. So, you don’t have to remove it each time you land to pack your kit. Just pack your glider, and reverse the SaK to enclose it.

 What exactly are the differences between Karma and Kamasutra II?

Although the harnesses have a different look, the design is really quite similar. But there are two major differences:

  • The Karma has a 17cm foam back protector, while the Kamasutra II has a 14cm protector.
  • The Karma does not have the Karve System© which allows you to change your position in flight, from reclined to more upright, without having to alter your harness settings.
    With the Karma, you set up one comfortable position which cannot be changed without altering the trimming. As a result, this harness is best suited to pilots having shorter flights, while the Kamasutra II is aimed at pilots who regularly do longer flights. Indeed, the ability to change position during a long XC flight is a great advantage in terms of comfort.
    Both harness have the same stabilisation system, the V-Stab System. Thanks to this, the Kamasutra II can be set up to be as stable as the Karma. On the other hand, we decided that the Karma can’t be as free as the Kamasutra II in the roll axis, even with all the adjustments of the V-Stab System fully open.

 What is the Karve System©?

The Karve System© is an exclusive Kortel Design, that allows pilots to switch from an upright to a supine position quite naturally, without touching any trimming. Lean back sliding your hips forward in the seat whilst pushing out on the stirrup to recline. If you encounter some resistance, then lengthen the stirrup straps a little. The shoulders straps should slide freely through the chest strap. If they don’t, then slacken the shoulder straps a little.
To return to an upright position, just relax and sit upright pushing yourself/hips back into your harness.
The Karve System© is based on a system of sliding webbing. The shoulder strap has an action on the lumbar part of the harness. The friction present in this system is high enough to make all the intermediate positions stable.

Because of this rubbing, the sliding webbing can wear out, and it must be inspected regularly (annually). If the protective fabric is damaged, it has to be changed. Otherwise, the main webbing itself will need replacement.
Both Kamasutra II et Kanibal II take advantage of the Karve System©.

 What is the V-Stab System©?

The V-Stab System© is an exclusive Kortel Design, which allows you to trim the stability of the harness without changing the width of the chest strap. The V-Stab System© works in the opposite way to the classical ABS system.
With the ABS, you have to shorten the chest strap in order to increase the stability of your harness. Consequently, you increase the risk of a twist in the event of big collapse. The V-Stab System© solves this problem and is even more efficient than the ABS.
Furthermore, the V-Stab System© is easily accessible in flight.

Both Karma and Kamasutra II have the V-Stab System©.

  What’s the difference between the Kamasutra II and Kanibal II?

The main difference is the stabilisation system. The Kamasutra II has the V-Stab System© (see above), while the Kanibal II has conventional leg and chest straps.

Consequently, the Kanibal II is made for pilots who don’t need a great deal of roll damping.
Furthermore, the Kanibal II is more rigid than the Kamasutra II. The back support is better and it gives more precise feedback. The range of positions from the Karve System© for the Kamasutra II is slightly wider than those for the Kanibal II.

 What about the accessibility of the Kanibal Race? I have heard that it’s only for top comp pilots?

And many other similar questions :

  • Am I able to fly the Race?
  • Is it so extreme?

There are many questions and often many wrong ideas concerning this name “Race”.
The fact that the Kanibal Race doesn’t get the Karve System©, together with the change of geometry of the main webbing and the increase in rigidity, makes the Kanibal Race the most precise harness in our range. People sometimes use the analogy of a car seat: the Kanibal Race is the rally seat, while the Kanibal II is the seat of a comfortable saloon. But that doesn’t mean that the Kanibal Race isn’t comfortable! The Kanibal Race remains an extremely comfortable harness, with arguably the best back support in the whole range.
Many people think that it is a very unstable harness. But in its original configuration, the Kanibal Race is fairly stable. Indeed the modern competition wings, because of their high arc and/or big aspect ratio, are sensitive in the roll axis. As a result, a harness which is too unstable, amplifies every little movement in the roll axis, which penalises straight line performance. But thanks to its numerous adjustments (see Kanibal Race: setting up the harness), especially the ability to adjust the height of the hangpoints, it is possible to change this behavior radically.
This is why the Kanibal Race is a pure race harness: the pilot has total control over his equipment.
