There is a reason this is the most iconic, functional and versatile single fin works on just about anything! The Greenough 4-A has been a True Ames bread and butter fin for close to 40 years now, and is still the most popular single fin design there is. A truly well-balanced fin...the full base coupled with the tapering, moderately flexible tip provides a solid amount of drive off the bottom, and an acute responsiveness through arcing turns. Designed for both speed generation and spending time surfing in the pocket, the 4-A is a fin that will hold when you need it to and release when the time is right. A fin that can do it all, throw one in your board and feel the success!

Product Features

  • Designed by George Greenough

Love this fin! Loosens up my 9'6 longboard, but still allows for a slower, smoother style of surfing. Works great at the small, beach break I usually surf.
