OUR MOST SUCCESSFUL 5-BATTEN SAIL OF ALL TIME IS BACK! COMBINED WITH THE “LIGHT DONE RIGHT” Construction AND ALL THE OTHER DESIGN CONCEPTS DEVELOPED OVER THE LAST TEN YEARS, THE REBIRTH OF THE DUKE SETS A NEW STANDARD FOR WIND-RANGE-ORIENTED MANEUVERABLE SAILS.

Our most successful 5-batten sail of all time made a sensational comeback in 2023, and for 2025, we’ve given it a facelift!

The DUKE combines our LIGHT DONE RIGHT Construction with all the other design concepts we’ve developed over the past ten years to set a new standard for wind-range-oriented handling sails.

The development of the DUKE was a 1.5-year project in which the end user was always at the center. As a starting point, we involved “real” end users who regularly use this type of sail, as well as our surf centers, to define a bucket list for the DUKE’s reincarnation. Here’s the result and how it came about:

Maximum wind range, especially in shifting and/or very gusty conditions.

This is the most important factor and the biggest advantage when choosing a 5-batten sail. A simple rule of thumb is that more battens mean more control and a wider wind range. Normally, this has a negative effect on performance at the lower end of the wind range, since more battens make it harder for the wind to fill the sail and make it less efficient to pump. That’s why we’ve adopted the BATTEN FREE CENTER concept from the SUPER_HERO. Instead of the usual even batten distribution, the DUKE has a larger gap between the foot batten and the batten above the Boom. This makes the gaff area easier to inflate and increases stability at the top (due to the higher batten density in this area). The second drawback is that each batten adds to the sail’s weight. That’s why there’s been a trend toward fewer battens in wave sails in recent years.

It feels super light in your hands, without falling apart after 1–2 seasons.

The lower weight of 4-batten sails was the main reason for the disappearance of 5-batten sails over the past decade. Fortunately, we’ve made some important design improvements over the last 10 years. The result of this development was the LIGHT DONE RIGHT CONSTRUCTION, which was introduced in 2022. By replacing the usual multi-layer reinforcements with a single layer of high-quality fabric and also introducing the ONE PIECE SLEEVE—the one-piece mast sleeve—we were able to reduce the total weight by 300 g. We are the only brand to have achieved these significant weight savings without reducing the thickness of the film or the XPly panels. This is the only way we can continue to offer our unmatched 5-year warranty. Another issue with reducing the film thickness is that the sail becomes spongy, as energy is lost due to increased stretch. This makes the sail feel heavier in your hands. That’s why our sails aren’t just lighter on the scale—they also feel extremely light on the water when you’re using them. Because that’s what really matters! Early

Planing Performance Even Without Excessive Pumping

To achieve maximum planing performance, the DUKE features a high pressure point distribution combined with a deep profile that gets the board planing early.

Super neutral during maneuvers

To make tricks and turns as easy as possible, the sail should feel completely neutral in your hands during maneuvers. That’s why the DUKE is designed with a pressure point positioned further forward. The forward pull cuts the power and shifts completely to neutral as soon as you open the sail or shift. This leads to a much higher success rate.

Good lift and control when jumping

The higher pressure point position also increases your airtime by generating lift, while the more forward-oriented pressure point helps you maintain control at all times.

Maximum range of use

One of the DUKE’s biggest advantages is its versatility. In bump-and-jump conditions, the Duke delivers pure excitement on your freewave board or, in a smaller size, for tearing it up on your freeride board. Thanks to its forward and high pressure point, it’s also well-suited for classic and even New School freestyle tricks. Last but not least, it’s a great sail for moderate wave and/or jump conditions, especially in gusty or challenging wind conditions. The new DUKE is thus a true all-around high-performance sail that challenges any handling-oriented sail.

Quick to rig

With all the features, markings, and guidelines we’ve developed over the past 40 years, it’s safe to say that no other sail can be rigged faster or more precisely than a DUOTONE sail. Even if you’re not a pro who sets up and trims your sail every day, you’ll still achieve the same precise trim. Because only with the right trim can you get 100% out of the sail’s performance.

A similar feel to the larger freeride/performance sails

Another important factor is that all the sails in your quiver should have a similar feel or handling. This applies even to pros, because even they usually need a whole day to get used to a sail

that feels completely different. The main reason sails feel different is the position of the pressure point in the sail. Fortunately, the DUKE also has a pressure point very similar to that of most modern freeride sails.

So as you can see, we’ve poured all our know-how and experience into developing the most sophisticated high-performance Jump N’ Ride sail ever.
