The True Ames Greenough 4-A Volan Single Fin has earned its place as the most versatile single fin ever designed. Created by George Greenough, this fin features a full base with a tapering, moderately flexible tip for a balance of drive, stability, and responsive turns. Its design, inspired by the tail fins of tuna, allows surfers to generate speed, stay in the pocket, and maneuver with precision. Handcrafted in Santa Barbara from solid fiberglass Volan panels, each fin is built with precision foils and tuned flex for superior performance. Available in multiple sizes, the 4-A works well on single fin longboards, mid-lengths, performance singles, and 2+1 setups.
The Smaller sizes (6.5" - 8") are phenomenal for 2 + 1 setups.
The larger sizes (8.5" - 10.5") are great to use for Single Fin setups.

Cleanline Staff Sammy Says:
"This is the perfect fin to liven up any performance single fin egg. I notice the flex you get from volan is more powerful out of your turns than normal glass. That flex combined with this particular fins long base projects you fast down the line for some high-speed trimming and carves. In my opinion, this fin by True Ames is the perfect single fin template for any mid-length."

Additional Info
The Greenough 4-A is not only the bread and butter of True Ames collection, but it’s also been the most popular single fin worldwide for decades–and for good reason–its incredible functionality and versatility means it’ll work on just about anything.
The man behind this revolutionary fin is George Greenough, whom the surf world is forever indebted to for his wave-riding performance innovations beginning in the '60s. Greenough ultimately paved the way from traditional logging to more progressive surfing in the pocket through the development of his Velo-Spoon kneeboard designs. To complement his kneeboards, Greenough found inspiration from mother nature for his fin templates through studying the tail fins of tuna–one of the fastest and most maneuverable fish in the ocean. The subsequent high-aspect ratio design he created allowed surfers to place themselves in more critical parts of the wave, execute more radical turns, and truly ushered in a new era of high performance capability.
History lesson aside, the Greenough 4-A is a truly well-balanced fin. Its full base coupled with a 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.
The True Ames Volan fins are fine-tuned with precision foils as well as proper flex. Crafted with a labor of love at their factory in Santa Barbara, CA, these fins undergo the strictest quality control. The True Ames Volan panels are meticulously hand-laid and templated ensuring optimal weave orientation and superior strength, with flex coming more from the body rather than just the tip. This enhances speed and projection off the bottom and through turns, making their Volan fins a pinnacle of the highest performance flex characteristics.
