The Duotone Foil Wing has been in development for a couple of years, and the design team have tested countless prototypes in order to create the perfect shape. During this process, it quickly became apparent that there were numerous advantages to using battens in the wing. They help to keep it rigid, reduce flutter and consequently drag, making it much more efficient. By utilising a boom, you also get unlimited choices of hand placements and a much more rigid connection to the wing itself. This helps with control and power development. The boom is also adjustable so it can be used with all of our foil wings. Particular attention was paid to the leech tension and shape; this area of the wing not only helps with upwind ability but also aids power control when pumping the wing and the foil. The Duotone Foil Wing has been fine-tuned to offer excellent responsiveness to rider input, and it is also incredibly light, giving you plenty of control on the water. The Duotone Foil Wing is taking foiling in a new direction where the only boundaries are your own imagination. All that is left for you is to take flight and enjoy the ride!
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 sheeted in a bit or a lot, so the rider can always get better stability 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.
• Windows, of course. Alan Cadiz (HST), who was an early adopter,
an early master of the sport, and is the master instructor,
insisted on big windows. They‘re super helpful whether
you‘re cruising around in traffic or surfing swells downwind.
FOIL BOOM SILVER SERIES
• High end 7075 aluminum -> Duotone Windsurfing Silver series standard
• Length adjustable 115cm to 175cm -> Fits all wing sizes
• Easy to assemble
• 4” coiled leash
• Stainless steel swivels
• 7mm underneath cord
• Adding battens improves wind range. A batten-less canopy that flaps a lot is a canopy that has a lot of drag. This drag makes the wing harder to handle in high wind and thus reduces the wing‘s wind range.
• Adding stability to the canopy and reducing flutter to a minimum
• Providing better upwind ability and therefore better for safety and versatility and increase top-end
MOST VERSATILE SETUP
Works for most adults
• 6‘11 SUP foil board, foil mast in middle of tracks (6‘3 and 6‘7 for advanced wing foilers)
• 75cm mast
• Aero Surf Foil 2000 long fuselage
• Aero Surf Foil 2000 (Aero Surf Foil 1500 for advanced wing foilers)
• For more speed or smaller rider, go with Aero Surf Foil 1500.
• For more lift or bigger rider, go with Aero Surf Foil 2500.
• Small riders (30 to 40kg) can use Duotone Spirit Surf 1250.
• Expert riders can go to smaller SUP and prone foil surf boards.
• Provides the best ease of use and highest level of performance.
• 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.
