DUOTONE - DUKE SLS 2025

Duotone Duke SLS 2025

The comeback of DUKE as a 5-batten Jump N’ Ride sail 2 years ago was a major success. It instantly became the most used and popular sail in the ION CLUB and DUOTONE PRO CENTERS worldwide.Now with the DUKE SLS we take this concept to the extreme! But instead of just swapping the materials, we have developed this sail from scratch to utilize the full potential of the materials and to give this sail an additional character. Because depending on the board, the DUKE SLS behaves like a chameleon:On lower drag single-fin boards (e.g. Freewave or small Freeride boards) the DUKE SLS has a slight forward pull (similar to the Original DUKE). On higher drag multi-fin wave boards, however, the pull is evenly distributed over both hands. On such boards, the new DUKE SLS has a very similar feel to the SUPER_HERO D/LAB making it really suitable even for proper wave sailing conditions.But how was this made possible?Well, it is a combination of an extremely sophisticated sail concept (3d-shaping, twist pattern and profile distribution) and the use of CARBON XPLY batten pockets. The DUKE SLS features a slightly forward draft position, but with a defined flexibility. Normally, this is a no-go for sails with “soft” epoxy battens, as any draft movement reduces the wind range. But this is where the CARBON XPLY batten pockets come into play: as Carbon has virtually no stretch, it locks the battens thus draft in its defined position - actually pretty similar to a Carbon batten.Believe it or not, in this way we virtually merged the advantages of the Original DUKE with those of the SUPER HERO D/LAB creating the ultimate 5-batten Wave

STRONG-LIGHT-SUPERIOR:400-500g lighter than the Original DUKE

BATTEN FREE CENTER:Larger gap between the foot batten and the batten above the boom >> better inflation (= planing power) in the boom area and improved stability in the upper sail area

VTS TAIL outhaul specs:Each sail carries individually defined visual indications for the correct outhaul extension (requires VTS TAIL boom).

iROCKET 2.0:Factory calibrated individual batten tensions using a torque wrench

SUPER-LIGHT BUMPER incl. VTS slot:The lightest protector on the market. The integrated vinyl viewing window allows to spot the lower edge of the mast. Once the perfect trim has been found, the optional Velcro patch can be used to “save” this position – saving time and ensuring maximum performance.
