Agile maneuvering, effortless acceleration, tighter turns and plenty of stability in the tube.
The Orcas have a concave foil similar to the Megalodons, with a twist added to the fin towards the tip, which helps you reach higher speeds and allows for tighter cuts during aggressive turns. The foil itself was developed at MIT for their human-powered airplanes!
These fins are very agile, feel great in normal surf but also hold strong in full on heavy conditions. This setup can be used as a twin, but it works best as part of a thruster or quad setup.
