DETAILS

SUPER HERO M.PLUS

Pour les plus passionnés des spécialistes, il existe la SUPER HERO de Viktor Fernandez en édition limitée M.PLUS, dotée d’une construction membranaire high tech extrêmement légère. Le corps membranaire est fabriqué par un producteur de voiles de yachting hautement spécialisé à partir d'installations de production guidées par ordinateur. L'objectif, outre une économie de poids maximale, était également d’obtenir une durabilité accrue par rapport aux voiles membranaires disponibles jusqu’ici. Dans ce cadre, nous nous fions à nos expériences en matière de yachting et utilisons un monofilm spécial 20 % plus épais ainsi qu’une quantité plus importante de colle. La première couche de film est recouverte de fibres Dyneema par un traceur qui suit exactement la direction des forces. Le parcours exact de ces fibres a été défini au préalable par simulation par ordinateur par le designer et le producteur. Ensuite, la couche supérieure est posée et étanchéifiée par procédé sous vide avant l’activation de la colle grâce à un apport thermique. Deux des quatre goussets de lattes sont laminés directement lors de ce processus. Le fourreau ainsi que sa protection, les deux autres goussets de lattes ainsi que les cosses sont achevés grâce au processus classique.
Le résultat est la SUPER HERO de haute qualité plus légère de 20 % (= 600 g), dont le poids plus limité se ressent particulièrement lors des manœuvres et lors de la manipulation. Jamais une voile de vague n’a été aussi légère et souple dans la main ni ne s’est comportée de manière aussi neutre lors de la navigation, surtout en raison de la sensation agréable d’élasticité que la membrane donne à la voile, ce qui permet, dans les situations de sous-voilé, d’obtenir une performance accrue. Sinon, la plage d’utilisation et le caractère global de la voile ne se distinguent pas fondamentalement de la SUPER HERO normale. Lors de la coupe du monde, Viktor Fernandez n'utilise plus que l’édition M.PLUS parce que ses avantages en termes de poids sont tout simplement imbattables.
Une technologie de pointe et des processus de production extrêmement coûteux font qu'il n’est possible de produire la SUPER HERO M.PLUS qu’en quantité très limitée pour un prix nettement au-dessus de la version normale.
Remarque importante : La SUPER HERO M.PLUS est une voile professionnelle high-tech qui jouit d’un poids minimal malgré un film membranaire optimisé. Sans surprise, cela se répercute sur la durabilité de la voile, c’est pourquoi l’édition M.PLUS est exclue de la garantie de 5 ans.

Brand Compatibility

Wanna know how other brands masts work with Duotone sails? Or how you should setup your personal sail quiver?

Sail><Mast Brand Compatibility

At DUOTONE we use a Medium Constant Curve for our masts (our bend percentages range between 61-63 bottom and 75-77 top depending on model and length). As this curve sits right in the middle within Constant Curve masts it offers the biggest compatibility of any bend curve. This makes our masts and sails the most compatible on the market.

HERE IS HOW GOOD OTHER BRAND MASTS WORK WITH OUR SAILS AND VICE VERSA:

  1. Challenger Sails, Ezzy, GA (2017 on), Goya, Gun Sails, KA Sails, Loft Sails, Naish Sails, NeilPryde (RDM masts), RRD, S2Maui, Sailloft, Sailworks, Severne (2014 on)
    >> 80-90% (depending on model and size)
     
  2. Hot Sails, NeilPryde (SDM masts), Point7, Simmer Style
    >> 70-80% (depending on model and size)
     
  3. Avanti, Gaastra (until 2016), Maui Sails, Severne (until 2013), Vandal
    >> Not compatible
Sail-Quiver Brand Compatibility

Most customers change their individual sail and mast sizes according to demand and therefore end up owning a quiver with different brands. When building up your personal sail quiver, you should try to combine sails that have a similar feel and behavior. The one decisive factor defining how similar or different one sail feels/behaves to another is the position of the draft, in both levels, vertical (high><low) and horizontal (forward><back). 

  • Freeride and slalom sails from the different brands nowadays feel quite similar since at least the horizontal draft position is forward oriented on nearly every sail today.
     
  • The biggest difference though you find with wave sails.

Basically there are 2 different kind of wave sails:

  1. Draft centered (= balanced pull on both hands) and low (to keep the sail controllable)
    These sails are the ideal companion for multi-fin boards. Since the balanced pull on both hands makes them super neutral in your hands they shine especially in real down the line conditions. On the other hand they feel very different to modern freeride and slalom sails (which are very forward pulling). So if you are using such draft back/low wave sails only very occasionally as your high wind flat water sail you might be better off with the second type of wave sails. 
     
  2. Draft forward and up (to still generate enough low end power)
    These sails work on both single- and multi-fin boards. With the forward pulling feeling they are more exiting/direct to sail and have a very similar feeling to modern freeride and slalom sails. In addition they are the ideal choice for side-onshore jumping conditions as the higher and forward oriented draft helps/accelerates rotations in the air (especially forward loops).

So when mixing your quiver with different sails/brands you should try to combine sails which have a similar draft position and thus feeling and behavior.

Just follow these guidelines:

  1. You are looking for a direct feeling wave sail especially for jumping. Or you need a smaller sail to complete your freeride or slalom sails.  Try to get draft forward/up wave sails. Typical examples are:
    Duotone Super Session / NP Zone / NP Combat / NP Atlas / Point7 Salt / Point7 Spy / Severne S1 / Severne Blade
     
  2. You are looking for a wave sail which is super neutral for down the line riding and very forgiving in nuking gusty conditions. Try to get draft centered/low wave sails. Typical examples are:
    Duotone Super Hero / GA IQ / GA Manic / Goya Fringe / Goya Banzai / Simmer Tricera / Simmer Blacktip / Simmer Icon
     
  3. Try to avoid combining draft forward/up- with draft centered/low sails in your quiver as these feel and behave extremely different.

Duotone design philosophies

Think different

Products have to be intuitive and as fast as possible to setup

With the information overkill nowadays no one has the time to read manuals anymore. Therefore we try hard to design our products as intuitive as possilbe to get you onto the water faster than with any other product. No wonder DUOTONE is called the feature world champ.
Here are some examples:

  • VTS 2.0
    The first "guess-free" visual trimming guide to clearly show the correct downhaul tension. Version 2.0 comes with a window in the protector to mark your individual trim once you have found your ideal setting. 
     
  • HTS 2.0
    By marking the draft position on the sail you immediately know where to position your harness lines. 
     
  • INDIVIDUAL BOOM LENGTH INDICATION
    The length of the boom changes with the angle to the mast. Therefore if you move your boom up or down you need to change the length of your boom. As the only brand we take that in consideration by printing 3 different boom lengths onto the clew and boom cutout so that you always know the correct length according to your body/boom height. 
     
  • iROCKET 2.0
    Every batten in a sail requires a different tension. That's why as the only brand we calibrate every single batten at the factory to the correct individual tension using a torque wrench. Since the screws are locked with screw glue you never have to touch them. Just rest asured to always have prefect batten tensions. 
Polyester webbing only

Eliminating stretch and loss of tension. If it’s good enough for safety belts, it’s good enough for windsurfers! We are 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.

TÊTIÈRE TT TOP
TÊTIÈRE TT TOPTÊTIÈRE TT TOP

Contrôle accru de la voile lorsque le vent souffle. À l’origine, le designer Kai Hopf avait conçu la TT TOP pour la WARP. La forme réduite, concave, améliore les rapports de tension, ce qui aboutit à une torsion tridimensionnelle plus efficace du haut de la voile. Cela signifie que lorsque la voie est soumise à un vent fort le haut se tort non seulement horizontalement mais également verticalement. Les rafales sont vraiment neutralisées et la prise en main du gréement facilitée, ce qui le rend utilisable sur une plus grande plage d’utilisation.

iRocket 2.0
iRocket 2.0iRocket 2.0

Ultra-léger et aérodynamique.

Un détail discret d’une efficacité incroyable. Les iROCKET 2.0 sont des étarqueurs de lattes ultra-légers, aérodynamiques et extrêmement stables. Ils sont constitués de composants de qualité, tel l’écrou en laiton auto-lubrifiant et résistant à l'eau salée avec vis en acier inoxydable, qui s’adapte à toutes les tensions de latte. L’iROCKET 2.0 est aussi à l’origine d'une véritable révolution :

Une tension de latte correcte à 100 % en sortie d’usine, un réglage qui dure toute une vie.

Nous effectuons déjà le calibrage de chaque latte en usine selon les indications du centre de développement. Pas au hasard mais avec une clé dynamométrique, pour une précision totale. De plus, le contre écrou est équipé de vis collées démontables qui préviennent le dérèglement de la tension. Cela signifie que la tension des lattes est parfaitement correcte et le restera, sans aucun réajustement nécessaire, pour toujours ! La clé fournie avec les lattes ne servira donc qu’à d’éventuels micro-réglages individuels ou dans le cas très rare où une latte se briserait.

Double Seam Technology

Deux fois plus de longévité, deux fois moins d’étirement. La fabrication DUOTONE est d’une qualité sans pareille qui confère à nos voiles une durée de vie nettement supérieure. Les coutures triple point zig-zag y contribuent énormément. Et il ne s’agit pas des coutures simples habituelles mais de coutures doubles ! Elle s’étirent sur toutes les zones exposées en cas de chute, ce qui augmente la résistance aux déchirures et réduit la variation de déformation de 50 % maximum au profit de la stabilité de profil et des performances.

Pas d’étirement, pas de perte de tension. Les matériaux qui ont fait leurs preuves dans les harnais de sécurité sont parfaits pour le windsurf ! Nous somme le seul fabricant à utiliser exclusivement des sangles en polyester pour les têtières (vario) comme pour les poulies. Par rapport au polypropylène classique, le polyester présente l’avantage d’un étirement quasi inexistant. Ainsi, même les voiles flambant neuves conservent leur pleine tension au point d’amure, leur étarquage n’a pas besoin d’être corrigé.

TRUE QUOTES

SUPER HERO M.PLUS

VICTOR FERNÁNDEZ
“Le Super Hero M.Plus est la voile de vague la plus légère que j'ai jamais navigué. Contrairement aux autres voiles à membrane, il n’ya pas que le poids physique sur la plage. Par exemple, le 4.7 se sent comme le Super Hero 3.7 classique entre vos mains sur l’eau.”

Sail Basics

Design physics of modern Windsurf sails

Materials

Especially in the top and towards the clew weight is key cause due to the leverage-effect you feel every gram a multiple times in your hands. Because of the quite limited amount of materials available though the only way to reduce the sail weight is by reducing the thickness of the materials. The secret is finding the sweet spot of lowest possible weight but without sacrificing durability and longevity/sustainability.

Modern Windsurf sails consist of the following raw materials:

(1) MAST SLEEVE MATERIAL
Rough woven Polyester fabric. The rough structure gives it a maximum abrasion resistance against impact from the outside (e.g. board contact or contact during rigging) as well as from the inside (through the mast).

(2) MONOFILM
Plastic film made out of Polyester available in clear- or colored versions. This hard plastic film has a very low stretch (for maximum performance) and doesn‘t absorb any water (dry weight = wet weight). Attention: monofilm isn't very UV-resistant. Therefore keep your sail out of direct sun light when not sailing. Also monofilm isn't very abrasion resistant.

(3) XPLY LAMINATE
2 thin layers of monofilm and a pattern of threads (out of Polyester or Dyneema) are glued together creating a sandwich laminate. The additional threads are supposed to function as a rip stop in case the film gets punctured (e.g. falling into the sail with your harness hook first). When using the same total thickness as monofilm (= same low stretch, same UV- and puncture-resistance) XPly is 30% heavier due to the additional adhesive (and threads).

(4) DACRON
Before discovering monofilm original Windsurf sails were made entirely out of Dacron. This woven fabric offers a very good abrasion resistance but is very stretchy plus elongates (means it grows with each use). Therefore nowadays mainly used for reinforcement patches to protect the monofilm and XPly panels in the high abrasion areas of your sail (foot, clew, top and outside of batten pockets).

(5) INSIGNIA
Dacron material with a self-adhesive side. Therefore it doesn‘t require seams when put on top of the film plus prevents water from getting in-between the film and the abrasion patches (= lower wet weight).

Materials
Design Features

BATTENS
Made out of glass- or carbon fiber either as solid version with smaller diameter (= stronger) or tube version with larger diameter (= stiffer). For a better understanding the mast is like the backbone of your sail whereas the battens act like the ribs of your sail keeping the profile in place. Same as the mast also the battens have individual profiles (thinner tip, thicker tail) matching the profile of the sail.
Simple rule: the more battens the more stable (= faster + bigger wind range) the sail becomes. But also the heavier the sail becomes as battens account for approx. 40% of the sails total weight. Therefore handling/wave-oriented sails usually come with 4-5 battens whereas performance oriented sails usually come with 6-7 battens.
As a second guideline smaller sail sizes require fewer battens than larger sizes.

CAMBERS
Usually there is a certain gap between the batten tip and the mast. This is necessary so that the batten can shift from one side of the mast to the other when sailing back and forth. A camber can be seen as a kind of connection between the batten tip and the mast filling out this gap.
This leads to much better aerodynamics as the cam enables a smooth transition between the thick mast into the thin sail body. In addition since the cam is braced against the mast the batten stabilises the sails profile much more effectively (sail becomes more stable = faster).
The downside is that the rotation from one side to the other becomes much harder. Plus the cambers need a certain space which requires a wider mast sleeve. This makes (water)starting much harder as the wider mast sleeve absorbs more water. Therefore cambers are mainly used on performance Freeride or high-performance Slalom sails.

FOOT ROACH
A sail with a lot of foot roach reduces the gap between the sail and the board (close the gap) which makes it more efficient/performance-oriented.
On the other hand a high cut foot with less foot roach improves the handling especially for all kind of ducking moves. 

PROFILE DEPTH
A deeper sail profile gives you more power and performance in general.
A flatter profile on the other hand improves the handling as the distance of the flat profile is much shorter when shifting from one side to the other.

BOOM- AND LUFF LENGTH
Together with the sail size all dimensions increase. Means in general the larger the sail the longer the boom- and luff lengths become.

Design Features
Sail size vs. body weight

Simple rule: a heavier sailor needs to take a larger sail size to get planning in the same wind compared to a lightweight.
Rough indication for the biggest sail size: to get going in the same wind a 10 kg heavier guy requires a 1 sqm larger sail.

Guidelines for building up your personal sail quiver

First you should define the biggest and smallest sail size you will need to cover all wind speeds you wanna sail in. This mainly depends on your body weight (see above).
Let’s take an “average” 75 kg sailor and let’s assume this guy wants to sail in “any kind” of wind.
- The biggest sail size this guy would need is something like a 7.3. With a capable 100-120 litre Freeride board this size would get him planning in approx. 8-10 knots.
- His smallest size would then be a 3.7. On a 70-80 litre (Free)Wave board our guy should be fine up to approx. 40-45 knots.

Second thing is to define the sizes in-between. Important to know: the wind pressure (which you feel in your hands) raises in square in relation to the wind speed. Therefore the smaller the sail size the smaller the size increments need to become. For large sails, the gap can be up to 1.5 sqm, while for very small sails it can go down to 0.3 sqm.

Taking all of this into account a typical quiver for our 75 kg guy could look as following:
7.3 - 6.0 - 5.3 - 4.7 - 4.2 - 3.7

Taking the “10 kg = 1 sqm” rule (see previous point) in consideration a typical quiver for an 85 kg guy could then be:
8.3 - 7.0 - 6.0 - 5-0 - 4.5 - 4.0

Why not blindly rig according to the specs printed on the sail?

You have bought all parts from the same brand but if you rig according to the specs printed on the sail it still feels somehow ackward.
Unfortunately every product has tolerances in production. And the bigger a product becomes the bigger the tolerances become. Therefore tolerances on a smartphone are hardly visible whereas tolerances on Windsurf equipment are non-deniable.
- The tolerances on the mast length are approx. +-5 mm.
- The tolerances on mast extensions and booms are approx. +-3 mm.
Furthermore, there is unfortunately still no standard among brands on how to measure the length of booms and extensions.
- On a sail with all its panels the tolerances over the whole luff length can add up to another +-5-10 mm.
In addition, even with monofilm sails the luff stretches in the first 3 times you use the sail due to the massive downhaul tension.
Adding up all these tolerances you start realising why the absolute numbers printed on your sail (especially the luff length) can only be an indication to adjust your mast extension- and boom lengths.

To achieve the correct downhaul tension please make sure to only rely on the VTS (Visual Trim System) markers in the top of every DUOTONE sail.
Always keep in mind there are exactly 2 things either of them potentially killing at least 30% of your sails performance:
1. The wrong mast (see first point under MAST BASICS on every mast page)
2. Wrong/insufficient downhaul tension

Sail Care
  1. After use in salt water, rinse or spray down with fresh water. At the very least at the end of a vacation or trip.
     
  2. When possible only roll up the sail once it has dried. Never store a rolled up sail for any extended periods of time unless it is dry.
     
  3. To dry, release the tension from the sail; if possible do not set out to dry in direct sunlight, and do not dry it by letting it flutter in the wind.
     
  4. Always roll the sail from top or bottom, keeping all battens under full tension in their sleeves!
     
  5. Use only recommended mast components for your sail in order to attain optimum performance.
     
  6. Do not wash your sail with harsh detergents or chemicals. Water and a mild soap are fine.
     
  7. Repair tears and holes in monofilm sails immediately to prevent further tearing. If proper repair is impossible (and this includes using the DUOTONE monofilm repair kit), at least seal the tear with normal tape or a sticker.
     
  8. The sails durability is directly related to
    a. the frequency of use
    b. sail care and
    c. UV-radiation (especially in monofilm sails)
    In places with high UV-radiation, store the sail in the shade, otherwise de-rig it.
