The downwind stand-up paddle (SUP) foiling scene has witnessed numerous innovations over the years, but few have made waves quite like Code’s R series foils. These cutting-edge hydrofoils are rapidly transforming how riders approach open-ocean downwinding, pushing the boundaries of what’s possible in this demanding discipline.
Breaking New Ground
“The R series represents a complete rethinking of downwind foil design,” explains veteran waterman and foil designer Mark Wilson. “We’re seeing riders achieve speeds and maintain glide in conditions that would have been impossible just a few years ago.”
The secret lies in Code’s innovative “Progressive Lift Technology” (PLT), a design philosophy that incorporates varying degrees of lift across different sections of the foil. This results in unprecedented stability at both low and high speeds, addressing one of the most significant challenges in downwind foiling.
Technical Innovation Meets Real-World Performance
The R series stands out with several key features:
- Optimized aspect ratio for maximum efficiency
- Variable thickness distribution for improved lift characteristics
- Proprietary carbon layup reducing weight while maintaining strength
- Novel wing tip design minimizing drag and increasing roll stability
These technical innovations translate directly into real-world benefits. Riders report longer glides, smoother transitions between bumps, and significantly reduced fatigue during extended sessions.
Performance Across the Spectrum
What truly sets the R series apart is its remarkable performance at both ends of the speed spectrum. At low speeds, the foil demonstrates exceptional lift and stability, making it easier for riders to maintain momentum through lulls and connect smaller bumps. “The low-end performance is game-changing,” notes professional rider Josh Ku. “You can maintain flight in conditions where you’d typically be slogging, which opens up more days for downwind sessions.”
At high speeds, the R series exhibits remarkable stability and control. World-champion rider James Casey, who has been instrumental in the foil’s development, explains: “The high-end performance is where you really see the R series shine. You can push these foils to speeds that would have been sketchy on traditional designs, but they remain predictable and controlled.”
Athletes Driving Innovation
What makes the R series particularly special is the direct involvement of elite athletes in its development. James Casey, Josh Ku, and Ben Tardrew aren’t just riders; they’re owners and key figures in driving the design progression. This unique arrangement has created a rapid feedback loop between real-world testing and design refinement.
“Being both owners and riders allows us to push the boundaries without compromise,” says Ben Tardrew. “When we discover something that could work better during a session, it goes straight into the development pipeline. There’s no corporate red tape or marketing decisions to wade through.”
Community Impact
The impact on the downwind foiling community has been profound. “These foils have opened up downwinding to a whole new group of riders,” notes Sarah Chen, a professional SUP athlete. “The learning curve isn’t as steep anymore, but they still offer plenty of performance for advanced riders.”
Local downwind groups from Hawaii to Australia report increased participation, with many citing the R series’ forgiving nature as a key factor in getting new riders hooked on the sport.
Looking Ahead
As the R series continues to evolve, many wonder what’s next for downwind foiling. With Casey, Ku, and Tardrew constantly pushing the boundaries in legendary downwind channels like Molokai and the Maliko run, the future looks promising. Their ongoing feedback and real-world testing continue to drive innovations in the design process.
“We’re just scratching the surface of what’s possible,” Casey hints. “The combination of owner-athlete input and cutting-edge design is going to keep pushing the sport forward.”
The verdict is clear: Code’s R series foils aren’t just another incremental improvement in foil design—they’re reshaping the future of downwind SUP foiling, one glide at a time.
