F-One Furtive v.1 kite
In 2014, Alex CAIZERGUES asked us for some custom kites to beat his own speed record of 56.62 kts. The design brief was to reach a maximum speed by riding over-powered with a 6.5m² on the speed run with an average wind of 50 kts…
F-one have therefore worked on a kite with more aspect ratio and 5 struts. But during the development, two things happened:
First we were surprised by the enjoyment we had when riding with this kite. This is due to the thrills it provides thanks to its performance (who doesn’t like speed and acceleration…?) but also thanks to its hang-time.
Then the foil riders in search for a long distance weapon became interested in this kite and immediately wanted to use it. After two years of development, the FURTIVE is ideal for long-distance racing, speed riding and hang-time sessions.
DESIGN
The FURTIVE features a high aspect ratio for high performance and 5 struts to control the profile. The leading edge arc is reduced to develop the maximum of power for a given area.
Its profile has been developed to ensure maximum traction at the edge of the window. Its W5 bridle is totally innovative and brings together the function of a bridle and a 5th line! We have called it W5 due to its W pattern which includes a central line to control the leading edge arc, like a 5th line. It provides perfect distortion control and the central line further helps with the depower of the kite.
On the WATER or in the AIR:
The FURTIVE provides a variety of sensations.
Twin-tip riding:
The kite is stable and the motion is fully under control. Bar feedback is super clear which makes you want to go faster all the time. Get ready, you are going to be willing to over-take anything else on the water!
Performance usually comes with jumping abilities. To improve this aspect, we have worked on the bar feeling, its manoeuvrability when sending the kite to the zenith and its boost during the jumps. The kite tows you way up and glides very well afterwards. Hang-times records are up for grabs!!
Long distance racing – gun or twin-tip:
Comfortable and fast, this kite is made for long distance courses and provides you with enough control to regulate your efforts during the long runs. Its flying range provides great tolerance to wind variations, especially in the high range.
Going hard upwind feels quite exceptional as the kite gives you the feel of being on an open reach. Its traction is really oriented towards the edge of the window with good support which saves you from pushing too much on the legs or on the back.
When reaching or going downwind, this kite will let you ride at full speed, helping the board to wipe away the sea state.
Foil riding:
To foil at high speed requires a lot of control and avoiding parasitic movements in the kite, especially wingtip flutter. If the kite moves, then you move too and so does your foil which inevitably results in losing control of your direction and balance.
Controlling the distortion of the kite during all flying phases has been the hardest goal to achieve during the development for foil riding but it has clearly benefitted all other disciplines.
Technology
| W5 BRIDLE The W5 bridle system acts as both a 5th line and a standard bridle, this is a genuine innovation! |  | We have called it W5 due to its W shaped layout with its central bridle which controls and totally secures the arc of the leading edge, just as a 5th line would do. It enables the kite to de-power uniformly to ensure perfect control of the power. |
|---|---|---|
| FORCE FRAME Kites with extended de-power ranges sustain more pressure across the canopy as they experience an increased frequency of use over a wider wind range. | Consequently F-ONE has developed a completely new structure for the Bandit, offering optimized durability with no additional weight gain. | The FORCE FRAME is a solid Dacron structure consisting of the leading edge, the trailing edge and the struts. This high strength skeleton structure is then covered with lightweight Spy material in the least vulnerable areas. |
| TECHNOFORCE TECHNOFORCE™ of TEIJIN is a high density Polyester fabric with a tear stopping structure using thin and high tension yarn. |  |
