Our four carbon masts cover all the needs of customers using the deep tuttle box system. These foil masts beat everything currently available on the market in terms of drag, flex stiffness and twist block. The technical advantages result in better control over your foil, a more relaxed ride in choppy conditions, easier jibing, more topspeed and less breakage. Experience a whole new level of control.

  • 95 DIM-S: This is our no-compromise comp slalom mast and not only the thinnest and narrowest but also the stiffest flex/twist currently used on the worldcup scene.

  • 95 DIM-M: Same outline as DIM-XL. Slightly thicker and wider for a more comfortable ride than the DIM-S. Your budget-friendly alternative to the 95 DIM-S mast.

  • 100 DIM-L: More narrow outline than Dim-M and Dim-XL. Made for the ultimate Course Racing competition performance without compromise. 

  • 100 DIM-XL: Same outline than DIM-M but 50mm longer at the head. Slightly thicker and wider than the DIM-L. Your budget alternative to the DIM-L.

Wide at the base with an extended front "nose" for added stiffness and less twist. With this design trick we're able to move the leading edge forward (to compensate for extensive mast rake that is actually moving the foil position backwards) which results in a more balanced and more effective fuselage position on the mast.
Narrow chord and thin profile at the fuselage too minimise drag and turbulences. Extra narrow chord for the DIM-S PWA slalom mast.

(Cutline given to adjust the AEON foil head to any boards using the "angled tuttle box system")


  • Compatible parts for all sports of windfoiling, winging, prone-foiling, sup-foiling and kite-foiling.

  • The measurably stiffest parts in flex and twist on the market.

  • The smartest, strongest and tightest part assembly and connections on the market.

  • The most advanced and precise low-tolerance production process on the market.


To protect the advantage of having the stiffest and thinnest parts we won’t name any construction secrets used for our masts.

As the only brand in the history of windsurfing being able to successfully produce hollow boards in more than 20 sizes (AirInside) our know-how in composite construction technology is literally miles ahead of competitor brands. With our own production run of “Fullcore” boards (EPS Core) we’ve set the industry’s bench mark for weight and tolerance quality of EPS production boards. With our AEON foil constructions we are leading the industry again by offering the thinnest and most high-aspect designs with the stiffest flex vs twist ratio.

All foil parts are using TX40 screw heads. The mast is using m6 screws to additionally secure the fuselage connection. The mast is designed with a Flat Head Deep Tuttle Box head with standard m6 inserts. A cutline is given to adapt the mast head to boards using the angled tuttle box system.

All AEON carbon parts have a "clear cote finish" to look optically appealing and perfect. This coating is sealing the carbon layers. Please note that sanding off this factory coating - partially or completely - will end the product warranty and any sanding will be fully at your own risk. Sanded AEON parts will change their look from glossy to matt finish. Always get some advise and guidance from experienced racers before sanding your foil parts. There is no general need to extensively sand the AEON carbon parts as we're using a very advanced production process. Only do so if you're 100% sure about what you're doing and why you're doing it.


Our target was to create high-performance foils with full compatibility for all foiling sports and disciplines.
We wanted this foil system to be commercially available at different price levels from the “whatever-it-takes world cup level” to the demanding needs of more price sensitive customers.
The AEON has been designed for maximum control – easing the fight of mastering 3-dimensional flight for both the skilled world cup rider fighting in the pack and the indermediate rider. Having one connection system for wind-, wing-, prone- and kite-foiling is a massive economic advantage for multi sport users and allows every rider to find his perfect personal setup easily. At the same time the multi-sport option opens a much bigger market to resell AEON foil parts. The AEON will be vailable in our retail network as a complete high-performance foil system that can fulfil any waterman's wishes and needs. One system can do it all!

The massive success of the AEON-Foil in both Windsurfing AND Wing-Foiling is the result of our PATRIK R&D crew’s precise and hard work. Our products are being developed in a unique hybrid process where the human brain (knowledge) and hands (feeling) are clearly leading the computer aided design – not the other way around. Like this we’re able to design perfect products that no “A.I.” (artificial intelligence) could ever create.
Fun-Fact: CFD (computational fluid dynamic) programs are created by humans, fed with data based on past practical tests, but will never be able to calculate completely new results outside their given data range. The PATRIK-Crew is practically developing and testing gear outside that software range and our results will be used later to feed and update currently available CFD programs.

After our R&D Team had found peak performance in individual outlines and shapes they had individual wishes for flex and twist resulting in different “magic” combinations of AEON parts. Offering all parts separately gives the top riders the freedom to find their magic setup while the indermediate riders can choose the best combo for their budget.
