F4 FOILS Wing

F4 FOILS Wing We design high-performance foils for wing, surf and downwind, built through real testing on the water.

About us
The bug bit after the America’s Cup in San Francisco. F4 has become obsessed with hydrofoils and been designing some of the world’s best for Windsurf, Windwing, Surf and Kitesurfing. We design and manufacture foils for F4 as well as several other brands and have become known as the design leaders in many different segments. Our focus is simple – to design the best hydrofoils possible for

each application. You can meet our core team on the beaches of San Francisco every day all season long. Values
Customer Centric – Our customers are what we are here for. Listen – Delivering products from the highest level of racing to consumers requires careful collaboration with you our end-users and listening and incorporating your feedback and needs into our products. Make it happen – we know how valuable your time on the water is. And we promise you to do our best to make sure you have enjoyable time on the water with the most advanced product on the market. The Environment – Our sport bring us in physical contact with nature. Our commitment is to protect it and enrich it so we can leave it better than we found it and allow future generations to enjoy it just as much as we do today. History
In 2008 Al Mirel, Chris Radkowski, and Ben Bamer – windsurfing and kitesurfing friends started F4 as a windsurfing fin company. Together they brought decades of experience with the sport, racing pedigree, engineering knowledge, Phd level math skills and endless enthusiasm and passion for the water sports. As the sports evolved and hydrofoiling came to the scene in 2013 we were the pioneers that turned it from a dream into the fastest growing market and the phenomenon that brought life back into windsurfing and extended into many other water sports.

Morning prone sessions done right.

“Loving the Orca 600 for smaller prone waves. For bigger days and more aggressive turns, the Manta 635 is the go-to.” 🤙🏽
