50 years of making fins - A family owned business


Rainbow Fin Company – known to most as RFC 


     In 1968, a group of young Santa Cruz surfers started building fins to supply the needs of the surfing industry. For five decades, Rainbow Fin Company has been a leading manufacturer of performance fins. Nothing like celebrating the 50th anniversary to bring back memories of how far RFC has come. 

     Most people think of RFC as a longboard fin company. But the truth is that RFC has been making shortboard fins when twin fins were introduced in the late 60’s early 70’s. Not stopping there, they have been producing fins for many other sports like: windsurfing, kiteboarding, wakeboarding, kayaking and SUP. RFC has also had the opportunity to make products for sailboats and research submarines.

     “It has been a great ride for 50 years of fun projects.” says Glen De Witt, “can’t wait for the next 50.”

     Rainbow Fin Co is still located in Santa Cruz, California where Glen and Kathy De Witt, along with their daughter, Sarah Broome, continue to manufacturer, test and design the product line.

     “I am so lucky to be a part of this family business” says Sarah Broome.

     The Rainbow family thanks you for your continued support in doing what we love.
