Wavegrinder surfboard fins use NASA, aerospace, and sailing-proven winglet science to create high-performance, low-drag surfboard fins for quick turns and high speed for longboards and shortboards. Wavegrinder now has symmetrical thrusters in black, red, and blue (12.9 sq. inch surface, 5.6 inches long), along with the longboard fin (30.5 sq. inch surface, 9.25-inches long). So unique, the fins are patented.
