ShortText:

It’s simply the biggest evolution on a wave sail in the Duotone history, deservedly carrying the D/LAB label. Because for us, D/LAB represents the maximum technically achievable, giving a glimpse into the future.

3 things set the SUPER_HERO D/LAB apart from any other sail out there:

Unseen wind range

Unbelievable but true, the wind range is extended in both directions means it gets planning earlier while offering more high-end control. To give you a better idea on the Original SUPER_HERO a typical quiver is 5.3 – 4.7 – 4.2. With the SUPER_HERO D/LAB though you can go 5.0 – 4.2 and cover the same range!

 

Ultra-light on the water

A responsive/dynamic sail feels lighter in your hands. On the other hand a spongy sail feels heavier in your hands “eating up” much of the physical weight advantage.

Technora/Dyneema and Kevlar have a high tear strength, but are not very stiff (only similar stiffness than the Polyester monofilm). Therefore, if being reduced in thickness to save weight (membrane and laminated or composite sails), these sails tend to become quite spongy and dull to ride. This sponginess results in a less efficient sail with a reduced wind range (especially when overpowered).

Carbon, on the other hand, is approx. 3-4 times stiffer than Technora/Dyneema and Kevlar. Using our INTELLIGENT CARBON XPLY CONSTRUCTION, the Duotone has found the ideal balance. The CARBON XPLY in the high load clew, top and tack areas guarantee unsurpassed low stretch and power transmission. However, the slightly more (re)flexing regular XPly in the body avoids the power from becoming uncontrollable. This makes the SUPER_HERO D/LAB extremely responsive and dynamic. There is no sail that feels lighter in your hands than the SUPER_HERO D/LAB!

Ultra-light without any sacrifice on durability

The easy and usual way to bring down the weight is by reducing the film/laminate thickness. Unfortunately reducing the film thickness has an over-proportional effect on the wear resistance and longevity in general. This is the reasons why reducing the weight the easy way by just reducing the skin thickness has never been an option for us - because all our products are designed and engineered according to our motto “LIGHT DONE RIGHT”.

For the SUPER_HERO D/LAB Duotone use the same film/laminate thickness as with our bomb-proof Original SUPER_HERO. The fusion bonding joining the panels are much stronger than traditional sewing (actually, the fusion bonding is even stronger than the materials itself). Hard to believe, but experience has shown that the SUPER_HERO D/LAB is even stronger than the Original SUPER_HERO. The Duoton back this up with our industry-leading 5-YEAR WARRANTY, something no other brand is able to offer.

Please note: after intensive uv radiation, the fusion bonding may take on a yellowish tint. Extensive lab and water tests confirm that this is purely aesthetic and has no influence on the mechanical properties/strength. That's why this is excluded from the warranty.

Lowest Sailing Weight

There is no sail that feels lighter in your hands than the SUPER_HERO D/LAB! Further details please find below under sailing weight



Inteligent Carbon XPLY Construction

CARBON XPLY in the high load clew and top area guarantees unsurpassed low stretch and power transmission. However, the slightly more (re)flexing regular XPLY in the body avoids the power from becoming uncontrollable


XPLY Plus

Laminate (100/150 micron) with the lowest stretch and best UV- and puncture resistance on the market



Features

3D Top Cap

Optimised pull. On regular top caps and pin systems, the webbing is connected in a “one-dimensional” way with the sail body (either side to side or front to back), which transfers the downhaul tension only in certain points. The 3D TOP CAP allows a “three-dimensional” and very widespread transition of the downhaul forces into the sail body. This eliminates top fluttering and ensures a progressive loose leech, extending the wind range. The integrated abrasion ribs eliminate the need for heavy, bulky reinforcements at the end of the luff sleeve


Set & Go Vario Top

No more trial and error when trying to find the best vario top setting. Even when first rigging up, the correct length of the vario top is found straight away. Clear length indicators mark out the perfect setting with reference to the mast length used, eliminating any need for testing or re-adjustments


Polyester Webbing Only

Eliminating stretch and loss of tension. If it’s good enough for safety harnesses, it’s good enough for windsurfers! Duotone is the only manufacturer to use only polyester webbing for the (vario) top and the tack roller. This advantage of this compared to conventional polypropylene is the negligible amount of stretch. As a result, even brand-new sails will retain full luff tension and will not need subsequent trimming


Double D Buckle

Inspired by high-strength climbing harnesses and Formula 1 helmets. The exclusive, two-part metal double-D buckle on the vario top, which replaces traditional solutions. This design guarantees the best trimming characteristics and eliminates all webbing slippage


TT Top

Improved sail control at higher winds. Designer Kai Hopf originally designed the TT TOP for the WARP. The reduced, concave shape improves tension conditions for a more effective, three-dimensional top twist. This means the top twists not only horizontally, but also vertically under strong winds. By completely neutralising gusts of wind, the rig is kept steady in the rider’s hands, and thus works in a much larger range of winds


Carbon XPly

Based on exclusive XPLY PLUS, the Duoton has added unidirectional carbon strings. This has virtually eliminated the stretch in the load direction, while retaining a certain give/elasticity in the other direction. They use CARBON XPLY in the high tension/stretch areas (top and clew). Especially in the clew area, this helps transfer the load from the clew into the sail body in the most efficient and direct way. This is exactly why all SLS sails feel even more direct compared to Duotone regular sails. Unlike membrane or laminated sails where the sail becomes softer/spongier due to the extremely thin film


VTS - Visual Trim System

Perfect trim and a huge range of use. You won’t find a quicker or more accurate way of trimming your sail. Even beginners can trim the sail in a matter of seconds to 100% accuracy. All you need to do is pull the luff until the top of the loose leech reaches the “lower wind limit” or “upper wind limit”. The VTS acts as a power boost, ensuring maximum performance and broader range of use


IRocket 2.0

Super-lightweight and aerodynamic. An inconspicuous detail with a massive impact. iROCKET 2.0 batten tensioners are super-lightweight, aerodynamic and highly stable, consisting of high-quality components such as a self-lubricating, salt-water-resistant brass nut with stainless-steel screw which can withstand all batten tensions. Furthermore, the iROCKET 2.0 is an essential component for a true windsurfing revolution. 100% correct batten tension, correctly adjusted when purchased and forever after


Epoxy Batten

Extremely stable, extremely break-resistant. Depending on the range of use, positioning in the sail and the necessary tension, the batten stress is enormous. In order to prevent breakages, the Duotone only fit into all solid battens extremely durable epoxy laminates which really can withstand anything and can live up to DUOTONE’s promises in terms of longevity


Mini Batten

These prevent unwanted leech flutter. Short and highly effective mini-battens which provide support for the areas between the battens and prevent undesirable flutter


XPly Plus

The Duotone use only 150 or 100 micron thick films for their exclusive XPLY PLUS. In an extensive series of tests, they have developed the ideal combination of necessary film thickness and number of threads. The X.PLY PLUS in particular, at 150 microns in thickness, boasts durability characteristics far in excess of previous laminates at minimal weight


Sleeve Opener

Frictionless insertion of the mast into the luff sleeve. An ingenious solution does away with the tedium of inserting the mast. The DUOTONE logo above the boom cutout gently opens the sleeve so that the mast can be threaded with one hand into the luff friction-free, without having to constantly make adjustments to the luff


Triple Tack Roller 3.0

Find the perfect trim with minimal effort. The integrated, nickel-plated brass triple roller minimizes the downhaul forces tremendously


Individual Boom Length Indication

The correct boom length without the need for trial and error. Because the boom is attached to the mast at different heights depending on body size, and because this creates a different angle to the mast, the boom length will vary. Specific recommendations for the correct length are printed directly on the luff sleeve at the boom level


HTS 2.0 Harnessline Trim System

Never position your harness lines incorrectly again. Do away with the tedium of adjusting to the optimum rope position, as well as the numb forearms and the endless fiddling around. The patented print on the sail shows exactly where the center of the harness line has to be. All you need to do is position the two ends symmetrically at the left and right of the print


VTS Tail Outhaul Specs

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


Duratech Foot

Long-term guarantee for the sail foot. When starting off on the water or catching up, the foot of the sail is constantly dragged over the nonslip coating, particularly for wide boards. With the exclusive DURATECH FOOT, the seams are completely protected within a large plastic channel so that the surface cannot chafe against seams and material


Twin Strap

This keeps the sail rolled up and holds the protector to the mast. A brilliantly simple fastening system which keeps the sail compact and closed after being rolled up and, when on the water, holds the mast protector closely to the mast
