Choosing
Your Mast

Discipline Specific Design

The Evolution Cedrus series is designed from the ground up to cater to the different manifestations of our sport. What mast is right for you depends on how you ride, what you ride, and where you ride.

CHOOSE BY RIDING STYLE

Evolution Surf

If you are riding "surfier" foils, typically at lower speeds, looking for maximum glide, Evolution Surf is made for you. Many wing foilers may go this route, especially if you like to de-power and ride swell.  Evolution Surf will reward riders for staying high, keeping the shorter chord length region at the water piercing zone.

Evolution Wind

If you like to sail close-hauled (upwind) in choppy/rough conditions or heavy seas and winds, you may want the added ventilation resistance and pointing ability of Evolution Wind. Due to the higher and longer water-piercing region, Evolution Wind will feel more forgiving and progressive as you move up and down the water column on the mast.

CHOOSE BY LENGTH

If you ride between 65 and 80cm, Evolution Surf is your mast, with industry-leading performance in the lower speed range (10-20kts) of prone foiling and the stiffness that Cedrus is known for.

If you ride longer than 85cm, you’ll need to go with Evolution Wind, which is optimized for the higher speeds associated with longer length masts.

Model Length Overlap

Between 80 and 85cm is a model overlap region, and both masts have comparable stiffness and strength. If you're ordering a mast in this region, consider your riding style when selecting the best mast for you.

What Length Should You Order?

A common question we get, with a very personal answer.

Cedrus masts are custom made to the inch/2.5cm. The optimum length is rider and location specific. Some prefer shorter masts for lower drag starts and a more responsive ride. Others like or need the additional length for big swell or high speeds. We suggest talking to the foilers at your local beach if you're having a hard time choosing. It could come down to typical surf sizes or depths at your local spot. If you're still unsure, you can contact us.

Ordering the Correct Length

Every brand measures mast length differently. Some measure to the top of the fuselage, some to the bottom of the mast, and others somewhere in between. It's best to measure your current setup before ordering a Cedrus mast if you're looking for a specific length. Otherwise, note that the total assembled length of a Cedrus is about 4-5cm more than the length we manufacture, and you order, due to the modular architecture.

FAQs

The Evolution masts are the result of engineering-based design. Just as a low-aspect surf foil looks different from a kite foil race wing, masts too can be optimized for different speeds and styles.

No. We have designed Evolution Cedrus to manage the loads from the biggest riders and foils. This being said: large foils are slow. The unanimous feedback we received before designing Evolution masts was a desire for better performance at speed. Evolution masts are designed for performance. They will work fine with larger foils, which are typically used for dock-starting or very light wind foiling at low speeds. But many of the masts designed and optimized for these forms of foiling are very thick, heavy, slow, and shorter length. Please understand that pairing a longer Evolution mast designed for high speeds with big foils designed to go slow may not yield the best performance. Please contact us to discuss your desired use case if you have concerns.

Ventilation occurs when air trapped between the water and the mast gets sucked down to the foils and causes loss of lift and subsequent crashing. It is typically associated with higher speeds, more aggressive angles of attack relative to the wind, and when the rider is more healed over. To prevent ventilation, Evolution Wind features a patented, longer chord length section to keep flow attached where the mast pierces the water. This longer chord length does result in a slight drag increase, but is the most effective way to make a ventilation-proof mast. Making the mast thinner only reduces ventilation resistance slightly, with minimal reduction in drag. Chord length is the best way to prevent ventilation, and is the technique used by all modern America's Cup and Sail GP foils, even at the expense of drag.

While Evolution Wind is the first foil mast to feature a patented ventilation-resistant water piercing region, we have not had any reports of ventilation with Evolution Surf either. We can't guarantee that it won't ever ventilate, because based on first principles of fluid dynamics, the shorter chord length (lower drag) region will experience flow separation before Evolution Wind's longer chord length. This sport is moving extremely fast, with riders constantly pushing boundaries, but for 99% of riders we can't imagine ventilation being an issue with Evolution Surf.

We're all beginners in this sport, but in all seriousness, the benefits of a stiffer, stronger, lower-drag mast will be appreciated more by beginners than advanced riders. It seems counter-intuitive but it's the truth: Experts in their field can rip anything, while beginners need the stability and performance of better-designed equipment to progress.

The marine environment is very tough on equipment, especially in places like Hawaii. We strongly recommend no matter where you live and ride to rinse and dry your mast after use, and to not leave adapters connected for extended periods of time. This being said, the mast is based on an 8 year-old design, the materials of which have been validated and proven under the most abusive customers without a single failure. See our owner's info page for more detailed care and use instructions.

Contrary to popular belief, mast thickness is far less important than other brands or riders will claim. In fact, chord length has twice the relative impact on drag due to it's influence on wetted area. Cedrus masts feature a 16mm thick profile throughout the majority of the length, but the performance of a mast is dependent on so much more than a single number. Evolution masts are the result of extensive multidisciplinary optimization efforts among engineers with 20-40+ years of experience in fields ranging from aerospace to automotive to America's Cup. Cedrus is faster, stiffer, and stronger than OEM masts through engineering and design, and the proof is in the riding.

Aluminum is a more efficient material at managing the complex loads of the board mount. Carbon suffers from a state of stress called "interlaminar tension" when the fibers are bent and curved at the interface to the board. This is why other brands' carbon masts get so big at the top. By machining aluminum instead, we can make the mount stronger, lighter, and cheaper than if it were molded directly into the mast. The aluminum mount is also removable, which is great for travel. It is shimmed at our facility for a tight fit to your mast, so you don't need to worry about screws loosening.

We use intermediate modulus fiber in a toughened epoxy prepreg form sourced from local aerospace suppliers and manufacturers. This material is stronger than high modulus grades of carbon fiber, and more consistent, stiffer, and stronger than wet-layups. It is also in-line with our core values of responsible manufacturing. Cedrus achieves industry-leading stiffness through proprietary design and engineering of the mast, not by relying on the material modulus.

No, the length of the mast is set at the time of assembly using our patented process. This allows us to manufacture nearly infinite lengths and achieve our industry-leading strength.

Most likely, yes! We have repaired many masts due to impact with the bottom or unsuspecting sea-life. Another benefit to our patented architecture is the easy repairability of rubber edges, or replacement or broken/bent adapters. If needed, the bottom of the mast can be machined flat again after impact-induced damaged. All masts feature stainless-steel threads that can be repaired or replaced in the event of damage.
