Outselling many other brands, the dynamic concept of the Duotone Echo features a boom, window and battens offering a superior experience.
For 2020, Duotone's design team has worked hard to enhance your feelings on the water and above it! A huge advantage of the Echo compared to softer wings, is its super stiff profile, achieved by the boom, battens and the new draft control rope.
• Easy handling • You choose the position of your grab on the boom, even if it is just a few milimeters - Easily sliding hands to the correct position allows the rider to more easily balance load on arms perfectly. • Stable/stiff feeling of the wing, no flexing - More solid connection to the wing and thus more effective pumping • Compatibility with every wing size due to length adjustment - One size boom fits all sizes of Duotone Foil Wings - Saves weight, bulk and cost • Our first prototypes had (like the Duotone iRig) an inflatable strut (or struts) and webbing handles. We quickly evolved to a version in which the inflatable center strut was enhanced with a pvc tube (boom) that attached to the strut.
DIHEDRAL - WING (UP) GEOMETRY • of roll stability, which is helpful for keeping the lower wingtip out of the water (the most common difficulty for beginners) and for stabilizing the wing during both straight-line riding and transitions
• This roll stability is most obvious when the Foil Wing is shee- ted in a bit or a lot, so the rider can always get better sta- bility by pulling in with the back hand. If the wind is strong,
just put the Foil Wing overhead (it will never just lift you up the way a kite will) and sheet in a bit for great automatic stability. • Balanced dihedral angle opted for a good blend of power and stability. WINDOW
• Windows, of course. Alan Cadiz (HST), who was an early ad- opter, an early master of the sport, and is the master instruc- tor, insisted on big windows. They‘re super helpful whether
you‘re cruising around in traffic or surfing swells downwind.
