True Ames Dual Tab Trailer Fin

A trailer fin is designed to add stability and drive to a quad or thruster setup without significantly increasing drag. By placing this smaller fin in the center, you can gain more control and hold through turns, especially in larger or faster surf.

Yes, this fin is specifically designed for the FCS dual-tab system. It is compatible with standard FCS fin boxes found on most performance surfboards.

The single-tab design offers more flexibility in positioning compared to fixed-base fins. By sliding the fin forward or backward within the box, you can fine-tune your board's pivot point, allowing you to prioritize either loose, snappy turns or more drawn-out, stable lines.

The ultra-thin foil is engineered to minimize drag as water flows over the fin. By reducing resistance, the fin helps maintain your board's speed through turns, making it a great choice for surfers looking to keep momentum in weaker or flatter sections of a wave.

Fiberglass (E-Glass) is generally preferred for its superior flex pattern and durability. Unlike molded plastic, fiberglass provides a more consistent, responsive feel that holds its shape under pressure, which is crucial for high-performance surfing.
