Duotone claims the following:
„The WARP 20.20 is the most competitive slalom sail we’ve ever built. More than 3 years of development went into the profile and design concept of the WARP 20.20: no compromise design, enormous propulsion, more acceleration at the start and after the jibe. The forward pull is much more controlled and effortless than at any other power slalom sail.“
At this point we have to mention that the sizes from 7.0m up to 9.0m are unchanged for this year. In recent years Marco Lang has mainly worked on the large sail sizes. Over the past year, the development team has worked intensively on the smaller sizes (5.0, 5.5 and 6.2). The testing was carried out in Tenerife, southern France and on Lake Garda. For the 5.5 alone, 16 prototypes were manufactured by Kai Hopf. “With the new loft in Tenerife we made a very good progress in the sizes 5.0, 5.5 and 6.2. Additional X-ply in the top area and the changes at batten 3 and 4 brought additional control. And a special 380cm mast for 5.0 and 5.5 helps, too,” says Marco Lang.
The 2020 WARP, the racing machine from Duotone, comes in 7 sizes in 2020. In 2019 there were still 8 sizes. The 9.4 got cancelled, the 5.4m becomes the 5.5m and the 4.7m is the 5.0m now. The 7.7m, our test size, is a core size, which works in many wind conditions and for many weight classes. A 7.7m also fits on a lot of boards from 67 to 80 cm board width and with fins from 36 to 44 cm, depending on skill level, weight, conditions and range of use. We rigged it on the Platinum SDM 460 mast with PowerXT and the Platinum 190 -250 boom.
But without Marco Lang nothing worked at first. Rigged out of the bag, our 7.7. lacks a bit of depth and the cambers did not rotate as promised. Only when test chief Marco came to the beach and tuned the sail – the final tuning on the Hyper Cam brought the decisive change – the sail opened in the upper area and got depth in the boom area and below.
We tested the 7.7 on the Jag LTD limited in 125 and 135 with the fin, which comes with the board. Of course, a high-end Slalom fin or high-end slalom board might have had a positive impact on the overall impression and speed.
Camber Rotation Test – Warp
Hyper Cam 2.0
Raoul Joa: “Every 10 years you make big steps in sail development. One big step was the change from 8 to 7 battens in all sizes of the WARP. The 4 cambers remained. Absolutely brand new is the new camber, the Hyper Cam 2.0. We invested 40.000 € for the new molds, 8 molds in total. From 2020 onwards the WARP doesn’t need spacer anymore. The times of spacers are over. If you want to increase the tension, you only turn with a Torx-key on the camber clockwise. The only downside: the new camber does not work on older sail models.”
As already mentioned Duotone invested a lot of budget and brain power from the development department of Ulrich “Uli” Bitterolf. In the end a real innovation in slalom gear tuning got developed! With the help of a Torx-key the new camber can be extended by turning the key clockwise. The profile increases. But in return the rotation can become worse. To reduce the profile and the tension you simply turn the camber counterclockwise with the Torx key. For example, if you reduce the pressure of the lower two cambers too much, the rotation will improve, but you will lose performance, stability, forward pull, acceleration and top speed.
So, with the Hyper Cam 2.0, a good compromise between tension, profile depth and camber rotation can be found very quickly, without having to de-rigg the sail. In addition, the tension on the luff and at the clew can of course be changed according to personal preference.
Time will tell if the new camber will also improve the performance on the water. The Duotone World Cup racers will compete with the fastest racers of the other sail manufacturers in 2020 and the results will show how efficient the function of the Hyper Cam 2.0 is.
