- The 4A is THE most iconic fin in the true Ames Greenough collection; it's functional and endlessly versatile and works on just about anything with a longboard fin box! The 4A is all about balance; the full base teamed with the tapering and moderately flexible tip delivers plenty of drive off the bottom and just the right amount of hold and responsiveness through expansive arcing turns on the open face. The perfect combination of speed generation and performance in the pocket, the 4A longboard fin has hold when you need it and the ability to release when the time is right." The Greenough 4-A has been our bread and butter for close to 40 years now, and is still the most popular single fin design there is" - True Ames.
