True Ames Greenough 4A Surfboard Fin

Some fins are built for one board. The 4A is not. It is the one you reach for when you want drive and response on almost anything, in almost any surf.

This is the True Ames Greenough 4A, the high-aspect template George Greenough's geometry gave the world. Solid fiberglass with a flat matte finish, a medium profile, a full base, and a tapering, moderately flexible tip that balances drive against responsiveness. Single fin box, screw and plate.
