Luderitz · 55 · 60 · 63 · 67 · 73 · 77 · 83 · 85




This year we continue the introduction of the new iSonic concept design in 4 new sizes : 60, 63, 77 and 83. Our new iSonics fly over the water with unprecedented control and confidence. Calm and composed in rougher conditions, they accelerate relentlessly and freely without sticking, while enhanced jibe capability ensures even more competitive overtaking potential at critical jibe marks. The revised outlines are significantly wider at 20cm off the tail, while maintaining original tuck line on the cut-outs. Extra leverage off the fin improves light wind range, while behind the fin, we added Arrow cut-aways and moved the rear footstraps further back. Finally, we optimised mast track positions further back. Those changes deliver a significant difference on the water, especially when racing fully powered up.

Arrow Cut Aways

Our new Arrow Cut Away design is featured on the 67, 73 and 85. It’s a diagonal cut away behind the fin that gives you a super loose ride. Do you remember how a board loads up when hitting a gust? That feeling is history.

Wider Tails

The new shapes got a wider tail while keeping the tuck line of the cut away unchanged. The result: More power for light wind and critical overtaking maneuvers. More control in tricky conditions.

Back Footstraps

The rear foot straps are further towards the back. This allows for less surface in the water and thus increases top end speed.

Mast track further back

Along with the back footstraps, we moved the mast track, further back which makes the board ride even more free.

Double Step Cutaways

Double Step Cutaways for added release and increased speed.

Drake Slick Footstraps

The Drake Slick footstraps are made with FSC-certified, sustainably sourced and plant-based Yulex foam. With 85% natural rubber content, CO² emitted during the manufacturing process is reduced by 80%. The remaining 15% of synthetic neoprene is kept to improve UV resistance. Carefully sourced with the smoothest fabric for a comfortable feel.



The iSonic Carbon Reflex is our flagship range. The light weight allows you to get going easier, plane through wind holes and get the best top speed. Carbon Reflex is our stiffest construction, giving you the best control when hitting chop and waves. Decks are built with the lightest grade of biaxial and uni-directional carbon fibre orientated between 45, 30 and 0 degrees for optimized flex and reflex characteristics. The bottom of the boards use an even lighter grade of uni-directional carbon fibre from nose to tail, with an extra 45 degree biaxial carbon layer in the tail area for added torsional stiffness.

Ultralight Weight Combined With New Materials

Ultralight weight, premium value and using more environmentally friendly materials. The bottom is built in full T700 uni-directional flat-woven carbon for maximum stiffness while the deck is 60% carbon, alternating between uni-directional and bi-axial carbon layers for optimized flex. The composite sandwich layers include the use of ultra-high density PET and PVC foam.

Versatile Vmax. Proven performance. In a practical, powerful package. This board was developed to live beyond the 50 knots barrier in Luderitz. In 2013 Juergen Van Der Noord achieved this windsurfing milestone on this board. Developed together with Ian Fox, this is the only speed board on the market with cut outs. Thanks to this feature it’s the only 44 wide board to go past 50 knots.
An ultra compact speed slalom board with a length of only 225cm. Light riders will appreciate the ability to keep the board on the water in high winds and open ocean speed sailors the top end speed. Developed with Matteo Iachino and Tristan Algret in extremely choppy water in Vietnam, this board was developed for ultimate high wind control and speed.
Flying at high speed, the tail of the board becomes the only surface touching the water. Our 2023 development focused on refining this area, with the clear goal to increase control, while decreasing resistance. The new wider forward outline provides balance and maintains a perfect, powered racing stance, while maximising confidence and control in strong winds. Behind the footstraps, a narrower outline optimises trim while reducing critical drag at maximum velocity. The combined outline improves glide, precision and planing speed though tight turns, ensuring better acceleration back to top speed. The iSonic 60 development involved extensive rough water testing in Tarifa by Matteo Iachino, Blanca Alabau, and Nico Prien. The result is an absolute open water high speed DefiWind weapon. Ideally matched with performance carbon fins around 32cm.
Development of the new iSonic 63, already renowned for an incredibly powerful low end, targeted extending the high end wind range with a more confident, locked in feel. The 2023 evolution delivers a more locked, secure feel, while extending all-important high end. Wider outline and volume at the back footstraps, while maintaining the tuck line, help engage the more powerful leeward rail when hitting the normal limits of control, keeping the iSonic 63 level, trimmed and comfortably controlled at full power, even in overpower conditions. Together with iSonic60, the new 63 was proven in the rough chop of Tarifa by Matteo Iachino, Blanca Alabau, and Nico Prien. Ideal with a 33cm carbon fin.
Our best ever. This is hands down the best slalom board we have ever made. Adding 1.5cm wider outline in the tail we drastically improved efficiency and speed in lighter winds. The new tail cut-aways changed in line with the 73 and 85, allowing you to fly the board freely over the chop. The most exciting feature about this board is the incredible control. No matter how windy or how choppy it is, the nose will never fly away. You just have to try it to experience how good it is. It’s the perfect medium size board for light riders and women.
Versatilty meets speed. A breakthrough 2022 design, with increased width to 73cm at the widest point and a massive 2cm added at the rear foot straps, while leaving the tuck line untouched. With this change, you have demonstrably more power in lighter winds and in critical situations; jibing or overtaking your friends. Or competitors. As the wind picks up, even more release - thanks to our new Arrow cut-away design at the very end of the tail - means less surface in the water and higher top end speeds. To top it off, we moved the rear foot straps and the mast track further back. You will be blown away by how much control you can have while flying this new board design over any water surface.
Developed in the lighter winds of Thailand together with the 83, the new iSonic 77 optimises rider stance and mast track rearwards, freeing the ride while improving fin leverage and easier control. Everyone was faster on this version. The hip outline combination ensures more performance in light winds, where the windward side of the board is more in play, while also improving competitive jibing. iSonic 77 adds confidence in stronger winds; most especially when harsh chop starts to challenge speed.
Developing the new iSonic 83 allowed us to ensure the new evolution improvements now benefit all sizes of the 2023 iSonic range. Improving both peak and average speeds, the versatility of the new outline designs was positive at every test. And through every turn. Consistency in ride and feel across all sizes allows riders to change board sizes without any need to adjust style, technique, or rider confidence, an important advantage in the heat of professional PWA competition. Or your local beach.
With foils becoming a true challenger to the big slalom boards, our most notable change in the new iSonic 85 was the increased tail width, giving you so much more low end power. This revised tail section gave significant control improvement; as the board starts to fly away in strong gusts, the tail section becomes activated and the nose trim stays lower, ensuring optimal control. And performance. The tuck lines remain unchanged, while tail cutaways in line with the smaller iSonics make this large board feel super loose under your feet.
