FEEL THE DIFFERENCE

Slingshot Sports

Slingshot Sports

Every foiler knows the feeling.

You connect a hard turn. Touch down for a split second. The board sticks. The rail grabs. Speed disappears. The glide is gone before you can recover.

That’s a result of drag.

Not just hydrodynamic drag but also system drag. The small inefficiencies between rider, board, mast, and foil that slowly disconnect you from the feeling you are chasing.

Project Drag was built to remove them.

Ken Adgate and Kyle Touhey shaped the boards around the hardest moments of a session: high speed turns, messy touchdowns, open ocean bumps, and recovering glide when conditions stop cooperating. Michael McKinley engineered the Adjustable Tuttle system to eliminate the movement and flex that traditional connections accept as normal. Bobby Johnston, with Edo Tanas and Trent Carter testing in real conditions, developed the UHM mast around one goal: a direct and predictable connection that stays composed under real load in real water.

The result is not a collection of products. It is a complete riding system designed to feel clean, precise, and connected when you are pushing hardest.

This is Project Drag.

Q&A Q: What problem were you trying to solve with Project Drag?

Ken: For me, winging was always about the high-speed touchdowns and deflections. I also wanted a board that felt seamless when making contact with the water during the most critical maneuvers, especially when fully railed over in turns. I wasn’t as worried about getting up on foil.

Then parawing was introduced to the sport, and we found it was much easier to learn and progress with a board that could peel off the surface at lower speeds. So Kyle and I went back to the drawing board and started thinking about a bottom shape that would work well at both low and high speeds.

After building so many different bottom shapes over the years, we had a pretty good understanding of what works and what doesn’t. A full rounded bottom works really well at low speed, but it can feel very tippy, while a V hull works great at speed and during touchdowns. So we decided to combine the two with our rocker line, and we found it created a pretty magic setup.

After a lot of builds with different dimensions, outlines, and rockers, we found something that worked extremely well and just needed to be fine-tuned. Once we perfected it, we realized the new shape worked so well that we both wing, parawing, and prone the same board.

Q&A Q: What problem were you trying to solve with Project Drag?

Kyle: So much focus and design work has gone into getting up on foil and maximizing early lift, but that often comes with compromises once you’re actually flying, whether it’s balance, unnecessary volume, swing weight, or poor touchdown performance. A lot of those designs can get in the way of a more physical pumping style, especially with parawing, and leave you constantly thinking about keeping the board out of the water, which limits how hard you can lean into turns or angle the board. I wanted something with the fewest possible compromises once I’m up on foil. I need all the help I can get, and I don’t want my board letting me down in the most critical and most fun moments.

Q&A Q: What does the Adjustable Tuttle system change for the rider?

Michael: The Adjustable Tuttle system keeps the stiffness, and zero drag of a traditional Tuttle box, but adds the ability to tune foil position and rake.

For the rider, that means you can precisely tune lift balance, front foot pressure, for different foil brands, conditions, and riding styles.

In practice, riders can: Adapt one board to multiple foil systems more easily. Move the foil slightly forward or back to tune balance. Adjust rake to change lift characteristics and front foot pressure The goal was not to replace the Tuttle standard, but to preserve the advantages of the Tuttle box while adding a practical tuning range for modern foil setups.

Q&A Q: What was the design brief for the Project Drag mast?

Bobby: To make the fastest possible mast while keeping equal or greater stiffness to our current masts.

We chose 80cm as the best length to keep the mast short for stiffness but still long enough to ride comfortably. We used the stiffest carbon fiber and put a steel collar in the mast to make the mast as stiff as possible. To reduce drag we tapered the mast down to 11.8mm thickness and a chord of 102mm to reduce the size of the profile as much as possible and went back to the drawing board on our mast profiles to find a faster profile.

Some boards are designed.

Some boards are shaped.

Ken Adgate shapes boards.

Decades of custom work for some of the best riders in the world, built one at a time by hand. The kind of boards riders spend years hoping to get access to.

Ken and Kyle Touhey were already refining shapes focused on high speed control, efficient recovery, and composure in difficult conditions. Michael McKinley was already solving the connection problem through the Adjustable Tuttle system.

Slingshot brought the platform together with Bobby Johnston and the design team and scaled it without losing what made it special.

Edo Tanas and Trent Carter took the final system into real ocean conditions and immediately understood what made it different.

Not a collection of parts.

One integrated system.

Ken and Kyles shaping.

Q&A Q: What was the first thing you noticed when you got on the Project Drag setup?

Edo: The first thing I noticed was the stiffness and responsiveness of the entire system. I couldn’t believe that the standard board connection I had always thought was solid enough was actually dampening so much of the power I was putting into the foil. As soon as I tried the Tuttle connection, everything felt more direct and precise. The energy transfer was immediate, and the foil responded exactly the way I wanted it to. I honestly didn’t realize changing the connection system alone could create such a big performance difference.

Q: How did the system change the way you ride?

Edo: It allows me to push the foil to its absolute limit in carving and turning because I have so much more control with significantly less flex through the mast and connection. I can pump longer and ride more efficiently because the energy is transferred directly from my feet into the mast, instead of being absorbed through a thick board construction and connection system. It’s also been incredibly fun for winging, where I feel another huge jump in performance. I can hold higher upwind angles, carry more speed through maneuvers, and my tacks and jibes feel much smoother and more controlled at high speeds.

Q: How would you describe the difference between the Project Drag mast and what you were riding before?

Edo: It honestly surprised me from the first session. I never expected a mast and connection system to make such a noticeable difference in overall performance. The biggest thing I feel is the increased stiffness throughout the entire setup, which gives me more control, confidence, and responsiveness. The mast itself is also extremely thin, which helps generate higher speeds with less drag. At the same time, the chord narrows closer to the foil, making the setup feel incredibly nimble and maneuverable while still staying stable. The board design also stands out. When it touches the water, it releases instantly instead of sticking, so touchdowns recover really smoothly. Overall, it feels like I can push so much harder in every aspect of riding while still staying fully in control.

Q&A Q: What was the first thing you noticed when you got on the Project Drag setup?

Trent: The first thing I noticed was the connection I felt when riding. The connectivity to the foil and instantaneous response was mind blowing. The thinner mast gave the existing foil I was using much more glide and a ton more top end.

Q: How did the system change the way you ride?

Trent: The system allows for much more speed while riding due to the mast and forgiving rail shape.

This allowed me to push harder, ride more efficiently, and bash sections that I would have been worried about getting bucked off before. During downwinders I glide further and pump through sections more efficiently. In the waves I can turn with much more precision and power in the pocket. When I’m winging I can reach much harder upwind with the finely tuned race DNA of the board.

Q: How would you describe the difference between the Project Drag mast and what you were riding before?

Trent: It is fundamentally a different sport riding the project drag mast compared to riding the plate mast I was riding before. Every single aspect of foiling is elevated. Turning is sharper and more direct. I can roll the foil over into turns with less effort and then come right out of it on demand. I can glide on swells that would have previously required me to pump my heart out. Mind you, this is all on the same foils below, just with the mast change. I have never had one change of my equipment make such a difference in my riding.
