Sustainability is the most important and pressing challenge of todays mankind to secure a livable mother earth for future generations to come!
Over the last 50 years Windsurfing has developed into a super high tech sport. But let's face it despite what others might tell you with the exception of aluminium booms and extensions Windsurfing products are a "mixture of petrol-based plastic trash". And most times up to 100% of this plastic trash are non-recycled (means "freshly produced") plastics.
At least as of today there are no eco-friendly substitutes existing offering the minimum requirements necessary to design modern Windsurfing products. Or why do you think no one wants to sail with wooden booms, aluminium masts or stretchy sails made of woven fabrics anymore?
There is only one sustainable way out of this dilemma:
MAKING LONGER LASTING PRODUCTS (LONGEVITY = SUSTAINABILITY)
A high performance product that lasts longer and best case can even be put into additional use on the second hand market is the best and only way to conserve the resources of our earth.
Of course light components have a massive impact on the performance and handling of your rig. That's why light weight is always on our briefing list when designing and engineering new products. And DUOTONE products are among or in many cases are the lightest on the market.
But durability and longevity were and will ALWAYS be on top of our priority list. Our industry leading warranty extensions bear witness to this philosophy:
- 2 year unconditional warranty on almost every hardware product (masts, booms and extensions+bases).
- 5 year warranty on 80% of our sails.
On sails we cannot emphasize enough that especially reducing the thickness of the monofilm and the XPly laminate has a radical influence on the longevity/sustainability. Reducing the film thickness by 50% reduces the UV-stability by 70%. Just to shortterm impress magazine testers or customers some brands use up to 70% thinner laminates/films than we do. This is not our understanding of sustainability.
However, since we are fully aware of the importance of sustainability, we cannot simply stop here.
>> Only we have stopped using any plastic for packaging our sails. This saves approx. 5 sqm of plastic film and foam per sail.
>> Only our aluminium products (booms and extensions+bases) are manufactured in a CO2 neutral production facility.
>> Only our aluminium products (booms and extensions+bases) are produced in Germany using 100% European raw materials in order to keep shipping distances (to our manufacture and then to our central warehouse) at a minimum.
>> Only our sail bags are made out of 100% recycled plastic.
>> Only we compensate all carbon emissions caused by our sails during manufacture and transport by supporting a hydropower carbon offset project in Sri Lanka, the country where our sails are produced.
SUPER HERO is THE ultimate wave sail which always performs optimally in all wave conditions around the globe. The perfectly balanced sail is the personal favourite of PWA Wave double world champion Victor Fernandez and is a real World Cup asset that is designed specifically for wave usage. Thanks to the absolutely neutral and perfectly balanced handling, its calm handling characteristics are unrivalled and it remains stable and highly controlled in every situation. The SUPER HERO feels like a three-batten design combined with the stability of a five-batten one. The specially developed profile blows out very efficiently and produces high propulsion even when underpowered, which is why it’s suitable for almost all riders, regardless of weight.
The SUPER HERO’s consistent evolution makes it an even better World Cup sail with an extremely wide range of use in the wave. It continues to give a top-end performance even under the brutal conditions of locations such as the Canary Islands or South Africa, remaining under perfect control with high winds and during extremely overpowered jumps. And yet it also boasts powerful acceleration capabilities at the lower wind limit, alongside an excellent on/off response, which would come in handy when participating in down-the-line surfing on Maui or Mauritius.
To achieve this extraordinary overall package, designer Kai Hopf is tasked with combining numerous individual designs into a single concept. This includes the BATTEN-FREE CENTRE, additional MINI BATTENS, the HOLLOW LOWER LEECH and RADIAL LOAD STRIPES running from the clew. Only then can this four-batten wave sail offer a wind range whose breadth is without rival. An optimised panel layout provides increased stability and control for all sizes 5.0 and up.
In terms of handling, the superiority of the SUPER HERO is beyond doubt thanks to its low weight. The batten rotation is beautifully soft, even with minimal outhaul tension. The top has a highly active role to play as well, thus supporting the forward pull. For this reason you can confidently choose a smaller sail size than with many other wave sails. Note: The SUPER HERO has been designed as a true wave sail and is only partially suitable as a flat-water, high-wind sail, for which we recommend the SUPER SESSION instead.
SUPER HERO HD
Although generally sharing the same structure, the SUPER HERO HD dispenses with monofilm even in the window panel.
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:
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).
Basically there are 2 different kind of wave sails:
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:
|PLATINUM / GOLD>SILVER||PLATINUM / GOLD>SILVER||PLATINUM / GOLD>SILVER||PLATINUM / GOLD>SILVER||PLATINUM / GOLD>SILVER||PLATINUM / GOLD>SILVER||PLATINUM / GOLD>SILVER||PLATINUM / GOLD>SILVER||PLATINUM / GOLD>SILVER||PLATINUM / GOLD>SILVER|
On modern wave sails you want to have a certain elasticity. The easiest way to „inject“ elasticity into a sail is by using Dacron for the luff panel.
Dacron has 2 disadvantages though:
Therefore Kai designs his wave sails with non-stretchy XPly luff panels. Instead he tries to implement elasticity into the sail through other design features. For example on the Super Hero which is the softest of our wave sails Kai implemented the FREE BOOM CONCEPT. Instead of the usual even batten distribution the Super Hero features a very big gap between the foot batten and the batten above the boom. This gap gives the sail "room to breath" but without becoming spongy. We call this PRECISE ELASTICITY.
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:
Our motto is clear: light is right but only if it doesn't go to costs of durability.
Our hardware products (booms, masts and extensions) are proven to be the lightest in the industry.
With our sails though we are not the lightest on the market (with the exception of the Super Hero M.Plus). The major reason for this is that we are using (much) thicker XPly laminates than some other brands.
The factors of puncture resistance, UV weathering resistance and stretch evidently depend ONLY on the thickness of the film used.
Puncture resistance and stretch have a linear relation to the thickness of the film. Means twice the thickness results in twice the strength against punctures with half the stretch.
Even more critical is UV resistance since here the relation to the thickness is overproportional. Means half the thickness reduces the UV-longevity by nearly 70%!
Some brands use XPly laminates which are 2/3rd thinner than ours in the upper sail area. Yes in the top you have less puncture issues and you can even get away with the increased strech. Unfortunately though the UV-exposure is the same all over the entire sail.
That's one of the reasons why the majority of Windsurf centres around the globe trust in DUOTONE products.
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.
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.
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.
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. We calibrate each individual batten at the factory according to development specifications. And we don’t just leave it up to blind intuition either – all battens are adjusted to 100% accuracy using torque wrenches. We also apply soluble screw adhesive to the locknuts so that the tension cannot be altered. This means that the batten tension remains absolutely correct and will never have to be adjusted again. The batten key included with the sail is therefore only needed for fine tuning or in the unlikely event of a batten breakage.
These prevent unwanted leech flutter.
Short and highly effective mini-battens which provide support for the areas between the battens and prevent undesirable flutter.
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, we 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.
What would you prefer? Maximum puncture resistance and UV weathering resistance with minimal stretch? Or (theoretically) improved ripstop properties?
We went with option A and developed the most durable laminate on the market. Because the factors of puncture resistance, durability and stretch evidently depend only on the thickness of the film used, we use only 150 or 100 micron thick films for our exclusive XPLY PLUS. In an extensive series of tests, we 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. This is also acknowledged by all the big surfing centres and rental equipment providers around the world, who place their trust in the unbeatable quality and longevity of our sails.
Double the durability with half as much stretch. DUOTONE manufactures products of unmatched quality which gives our sails a significantly longer lifetime. A key feature which helps to achieve this is the triple-stitch zig-zag seams. Unlike other products with their single-seam design, these are double-seam. They cover all exposed crash areas, which increases tear resistance and reduces bending-elongation by up to 50%, boosting profile stability and performance.
Guaranteed quality – no other brand offers anything close to it.
Keeping weight to a minimum is a great idea. But if necessary reinforcements are reduced too much, the product’s service life will automatically get shorter. DUOTONE has struck the perfect balance between weight and durability. To prove our dedication to ensuring durability and unique quality, almost all of our sails come with a 2+3 year warranty (excluding monofilm). To secure warranty claims fully, please remember to register at www.duotonesports.com straight after your purchase. Otherwise, only statutory warranty claims will be accepted. This is valid only for original owners.
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.
Extremely stable luff reinforcement. The area around the boom cutout is exposed to extreme wear and tear as the luff panel gets folded when inserting and pulling out the mast. This “accordion effect” can lead to tears in the monofilm after a while. The flexible DURA LUFF PATCH reinforces this area making for a soft transition into the monofilm to avoid film breakage.
A real innovation that offers additional value is the new iBUMPER 2.0, since in addition to its function as a lightweight and reliable mast protector it is also useful as a trimming tool. After stretching on a new sail, the best indicator for optimum trim is the position of the mast end at the height of the protector. For this reason, the new iBUMPER 2.0 now has a vinyl viewing window so that the lower edge of the mast can be identified. Once the perfect trim has been found, the optional Velcro patch can be used to “save” this position – saving time and ensuring maximum performance.
Eliminating stretch and loss of tension. If it’s good enough for safety harnesses, 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.
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.
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.
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.
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.
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.
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 centre 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.
Find the perfect trim with minimal effort.
The integrated, nickel-plated brass triple roller minimizes the downhaul forces tremendously.
30% higher ripstop strength in the critical foot area. We have developed the TRI PLY PLUS 150 specifically for highly stressed foot areas used by intermediate riders and also in wave and Bump&Jump sails. It consists of two layers of thicker monofilm and a third thread, which together form an extremely durable polyester film/thread construction.
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).
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).
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).
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).
Wanna know more details or looking for DUOTONE sail spare parts - here you go
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.
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.
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.
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.
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.
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
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
