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.

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.
