Crafting Quality Surfboard Fins Since 1979

True Ames is on a mission to provide the highest quality and best performing surfboard fins available. Through the commitment to our partnerships with some of surfing’s core craftsmen, we are dedicated to providing all of our customers with premium products, continued innovation, and production excellence. It is our ambition to celebrate surfing’s rich history through honoring designs of the past, while simultaneously progressing into the future with new fin concepts built upon lasting relationships.

Each True Ames fin is handcrafted in Santa Barbara.

A fin design is only as good as the materials used for construction. At True Ames we carefully select the most well-suited types of fabrics for producing the highest quality fins available.


The Resin Transfer Method (RTM) allows us to construct a composite fin, inside of which hexagonal pieces of lightweight coremat displace fiberglass and resin. The result: a fin that is 25% lighter than a normal solid fiberglass fin, without compromising performance. Our Hexcore fins have become the standard by which system fins are measured.


In order to achieve the performance characteristics that have become the standard of solid fiberglass surf fins, we use E-glass. It is the most common type of fiberglass used in surfboard construction, and its qualities translate with great success into fin construction. E-glass has excellent flex characteristics and performance longevity, while featuring the bonus of outstanding color vibrancy that allows for the variety of colors we offer.


Handmade by the True Ames team in Santa Barbara, CA, the appeal of the fins we offer with volan fiberglass construction goes much deeper than their distinctive coke-bottle-green color and raw finish. Each of our volan fins is cut from the highest quality fiberglass and perfectly aligned for optimal flex characteristics. These limited supply fins flex from the body of the fin thereby producing increased speed and projection off the bottom and through turns.
