True Ames Greenough 4-A Volan

This fin is designed specifically for single-fin longboards. Its versatile template pairs well with everything from traditional logs to mid-length displacement hulls, providing a stable, predictable feel regardless of the board's rocker profile.

Volan fiberglass is heavier and stiffer than standard glass, which adds a distinct sense of momentum and stability to your turns. It creates a smooth, dampened flex pattern that feels more connected to the wave face compared to lighter, more brittle materials.

It strikes a balance between both. The full base provides the drive you need to set up for turns, while the tapered tip allows for enough release to pivot through arcing carves. While not a dedicated noserider fin, it offers enough hold to keep you stable on the nose in clean conditions.

Unlike fins that only flex at the very end, the Greenough 4-A is foiled to distribute flex through the entire body of the fin. This results in a more consistent, predictable energy return that helps you maintain speed through the middle of your turn rather than just snapping back at the end.

Yes, this fin uses a standard US Box system, which is the industry standard for single-fin longboards. It includes a screw and plate, making it compatible with almost any modern longboard box.
