1 – WARP TENSION LINE

Woven fabrics feature a longitudinal 0° yarn (Warp) and a transversal 90° yarn (Weft). Therefore, a fabric has great elongation resistance and strength capacities if you apply tension at 0° or 90° along the yarns. But it will deform and stretch when tension is applied at, let’s say, 45°.

2 – LOAD CONTROL PANELING

When engineering the load control paneling, we make sure that fabrics panels are warp/weft oriented, meaning that the load path runs through the yarns. Fabric and seams are then in the best position to receive tensions and maintain the original kite shape.

3 – STAGGERED SEAMS

Most of the kite’s back lines tension is distributed through the trailing-edge panels and seams. As seams are significantly stiffer than the fabric they join, they tend to strain under loads and therefore deform the profile. The staggered seams break that line of tension by balancing the stiffness between seams and cloth, which helps distribute the load over a wider area and maintain the original shape even under high loads.

4 – FABRIC WEIGHT MANAGEMENT

Our sails feature four different cloth weights, from 52 up to 155gr/m². Sail engineering allows us to control our shape and drive load tensions without using heavy fabrics or bulky designs, therefore we can reduce fabric’s weight and use. It results in a lighter, optimized kite.

DELTA C-SHAPE is a patented design used by F-ONE on all kites for the past 15 years.

This shape was the result of a design research towards maximum optimization of the aerodynamic performances of the kite and of its depower. It gives the possibility to fit more canopy area in the middle sections to create more projected area while the C Shape makes sure the kite remains responsive and fluid.

Original staggered seams have been implemented on critical parts of the kites. The seam’s tension line is broken offering a perfectly leveled canopy profile when the kite is fully powered.

The fabric is orientated towards tension. The perfectly even canopy profile brings a sensational stability without feeling disturbances in the bar.

SHEETED IN The back line is released and the forces go through the front connector. The bar pressure increases and the maneuvrability is less direct. It offers a very progressive bar with a feeling of a sheeted out back connector while we sheet in, therefore the pressure increases progressively.

SHEETED OUT The kite tilts and the back line stiffens. The tensions move to the trailing edge which has several effects: - less flapping - better start - maneuvrability with less pressure.

HIGH TENSION TUNING When the kite is sheeted out with the upper knot tuning (1): -kite’s maneuvrability increases -bar pressure reduces

LOW TENSION TUNING When the kite is sheeted in with the lower knot tuning (2): - kite’s maneuvrability reduces - bar pressure increases
