Brand Story

Founded in 2008 by friends Al Mirel and Chris Radkowski, F4 was born from a shared passion for water sports and adventure. Inspired by the thrill of the America’s Cup and the rise of hydrofoiling in 2013, we quickly became pioneers in this exciting arena, innovating across wind winging, windsurf foiling, and more.

Starting in Silicon Valley, we crafted our first prototypes in garages. Today, our dedicated team engages with the community on the beaches of San Francisco and the Black Sea, celebrating our love for the sport. With multiple PWA race victories and speed records, we remain committed to enhancing your experience on the water.

By harnessing cutting-edge technology and feedback from our riders, we create premium, race-proven products for every foiling enthusiast. Come ride the wave of innovation with us and discover what’s possible on the water!

At F4, we are driven by an unrelenting passion for speed, racing, and the exhilarating world of water sports. Our mission is to design and manufacture the fastest, most stable, and versatile foils on the market. Achieving this requires constant research, innovative thinking, and countless hours of rigorous testing. Our hydrofoils are crafted from a unique blend of 3D design, fluid dynamics, and advanced composite materials, ensuring peak performance on the water.
