FINS DEVELOPED BY RACERS FOR RACERS

F4 Fins was started by avid formula windsurfing racers in the San Francisco Bay because good racing fins had become either too expensive or unobtainable. The wind and water conditions, as well as the experienced racing fleet in the San Francisco Bay, provide the ideal proving grounds for developing the next generation racing fins. With help from Boogie of C3 on the design and manufacturing, combined with daily testing in the Bay waters, refinements can be quickly incorporated, resulting in an improved and constantly evolving product. After nearly a three years of effort, F4 fins are proving to be the winner's choice.

Our goal is to make the worlds best fins for racing and ensure that they are available at reasonable cost and in a reasonable time frame. Its important to us to encourage new and junior racers to participate in formula and slalom racing.

WHY WE ARE DIFFERENT

We are racers just like you who simply want the best fins at a reasonable price in a reasonable time. The key to our success is the local racers who are sailing and testing EVERY day during our season, from early March to late October. This allows us to deliver a fin that is build with  the combined knowledge and feedback from one of the most competitive fleets in the world.

WHY OUR FINS ARE DIFFERENT

An F4 Fin utilizes an advanced composite layup that provides a softer feel, enabling greater control in a wider range of conditions. Our advanced composite design produces a consistent, responsive and longer-lasting fin with soft lateral and stiff torsional flex as compared to other formula fins. We have found that this softer feel, combined with a bullet-proof layup, gives you a fin with the optimal speed and control which makes the rest of your kit work more effortlessly. Call us prejudiced, but we've seen it all too often: racers spend too much on boards and sails, and treat the fin as an afterthought, when the fin can be the single most important component in a racer's arsenal. It's why some professional racers hold onto and baby "special" fins even as they move from one board or sail sponsor to another.

OUR MISSION

Our goal is to make the worlds best fins for racing and ensure that they are available at reasonable cost and in a reasonable time frame. We believe that this is important for the the sport and for the enjoyment of all competitors. One of our primary goals to to support junior racers. We believe that making the right fins and equipment available to juniors will help toincrease the total level of participation and overall interest in our sport.
