Duotone Mag 2024

03 02 Where and by whom are the Duotone foils developed? Our foil designer Jerome Bonieux (picture on the right) lives in Mauritius . Finn and Jeffrey Spencer are testing on Maui. Klaas Voget, Division Manager Product & Marketing Wing Foiling, tests on the Baltic Sea, in Denmark, Tenerife and wherever else he happens to be. Craig Gertenbach, Division Manager Sales Wing Foiling, provides his input from Lake Garda, the Bavarian lakes or Cape Town. Leopold Fricke, Foil Developer at Duotone partner iXent, prefers to ride on Lake Chiemsee and Lake Garda. Alexander Held, Product Manager Foil, is where all the threads come together at the Duotone headquarters. It is precisely this diversity that makes us so strong, that we test in so many different places with very different rider profiles and don’t just develop our foils in one place, with a certain salt content in the water and always the same water temperature. A foil with a lot of lift in the water of Maui feels completely different in the fresh water of a Bavarian lake where it perhaps requires more angle in the foil or a larger stabilizer. The warm lagoon of Mauritius differs from the cold Kieler Förde with its lower salt content. The steep small wave of Lake Garda differs from the flat water of Langebaan near Cape Town. What influences the foil system in which conditions? Sensing these subtleties is the strength of our diverse team. After all, our customers are similarly scattered all over the world at different spots. 04 What is the ideal trim for a Duotone foil? The mast of a Duotone foil should always be positioned in the middle of a track of a Duotone board. Then the basic trim fits. A different foil for a different area of use, or smaller or larger foils all work with the identical, centered mast position. From this position, you can then adjust it forwards (earlier lift, more pop for jumps) or backwards (takes pressure off the front foot in gusts) depending on your personal preferences. F o i l m a n i a What makes the Duotone foils so special? Our foils have that certain feel-good character, that special Duotone riding experience. Even on first contact with our foils, it feels as if you’ve always ridden them. A Duotone foil is easy to ride, but still feels lively, you don’t have to think much about settings. Achieving this is a very fine line in development. Even our specialized foils for certain skill levels and areas of use are easily accessible. You can enjoy any of our foils without feeling overwhelmed. Nevertheless, the smaller sizes are suitable for radical riding. However, the riding characteristics do not change and remain homogeneous within a range, e.g. from the 1305 down to the 725. A small foil should not feel any different from a large one, even though it provides more speed and maneuverability, the basic character remains the same. And a large wing can also feel as radical as a small one. We achieve this balance through very precise calculations and the coordination of flex, profile, roll stability and pitching moment. Of course, our foils have different areas of use. But when switching from Free to Carve 2.0, for example, you don’t feel like you’re in a different world, you know certain characteristics. You don’t have to get used to it for a long time and you can immediately develop further. You never feel unfamiliar with Duotone foils, even if you switch to a different foil line.
