Q-Power Line The Design Goal:

To produce the best line in the world specifically for traction flying.Up to this point in time all line used for KiteSurfing has been a compromise, utilizing line developed for other industries or dual-line stunt flying. KiteSurfing has specific needs and Q-POWERLINE is the first line that has been designed specifically to meet the needs of demanding KiteSurfers. Q-POWERLINE has been engineered specifically to address these needs. KiteSurfing Line Requirements: 1)Provide low to no stretch.-Line stretch is normally uneven due to differing pressures on top and bottom lines, this causes the boat kite to go “out of tune” and requires frequent “re-equalization of lines”.-Line stretch tends to inhibit “feel” when flying the kite-With braided line, the fibers try to return to their stable state (that of a linear or straight line), when tension is applied, from their normal braid angle. The continual tendency for the braid to tighten with time and for the fibers to assume a more linear orientation results in continual “stretch”over and above the actual stretch of the fiber. Q-POWERLINE utilizes an internal core consisting of a linear bundle of continuous Spectra fibers. All strength in the line is attributed to the core only, with the over-braid’s function limited to keeping the bundle together, keeping dirt out of the structure and stiffening the line. Since the internal fibers are linear from the start, there is no continuous ‘stretch’as found in traditional braided line, where the braid tightens with use. Any stretch in the line is therefore limited to the elongation of the actual fibers, which is minimal when compared to braided line. This miminized tendency to stretch and long term length stability. - dramatically increases the pilots ability to ‘feel’what the kite is doing - improves kite responsiveness - minimizes the need to ‘retune’the flying line lengths - reduces kite instability caused by unequal ‘stretching’of the leading and trailing edge flying lines 2)Make the cross-section round to minimize ribboning effect.-What is ribboning effect?-The tendency for normal hollow braided Spectra line to flatten and then act like a ribbon in the air, vibrating back and forth. Thereby having a much greater effective drag than the apparent static diameter would suggest. Q-POWERLINE ’sinternal core bundle of fibers resists the tendency to flatten out and when compared to traditional braided line Q-POWERLINE has a very round cross-section. This round cross-sectionminimizes the effective diameter and drag. Traditional braided line can have an effective diameter of up to 5X the lines static diameter, substantially increasing parasitic drag. Q-POWER LINE ’ sround cross-section minimizes any ribboning effect caused by flying linesflattening out and therefore effective line drag is minimized. Minimized drag equals maximized performance.
