Amidst his wind generators, blue ocean boats, and camera housings, George Greenough had enough energy to revolutionize fin design with the True Ames Fins Greenough 4A Fin. The full base coupled with the tapering, moderately flexible tip creates a balance that transcends and complements so many aspects of surfing. Of course a unique understanding of his aquatic fish friends is the foundation here. Install the 4-A on any performance surf vehicle and you will find instant bliss.
