True Ames Surfboard Fins are renowned in the surfing world for their quality, design, and history. Founded in 1979, True Ames began by crafting fins to enhance performance. The company’s first fins were made for a small group of surfers in California. Over the years, True Ames expanded its reach, making fins for top athletes.

Their early designs were influenced by the growing interest in performance surfing during the 1970s. True Ames quickly became a leader in the fin-making industry. The fins' designs focused on improving speed, control, and turning ability. Each fin was handcrafted with meticulous attention to detail and functionality. As the sport evolved, True Ames fins adapted to new trends and technologies.

The brand has always been known for using high-quality materials in its fins. True Ames has also collaborated with legendary surfers to create custom fins. One of their iconic fins was the "Greenough" model, inspired by George Greenough's surfboard designs. The company’s innovations helped shape the modern surfboard fin as we know it today. True Ames continues to be an essential part of surfboard fin and board design, offering fins for all types of surfing.

The company’s fins are used in both competitive and recreational surfing worldwide. With decades of expertise, True Ames remains a trusted name in the surf industry. Their fins are a testament to the sport’s history and continual innovation.

A "trailer" fin is a smaller, rear-mounted fin often used in conjunction with a twin fin setup on a surfboard. Twin fins typically consist of two larger fins positioned at the back of the board. The trailer fin, however, sits slightly behind these fins, acting as a stabilizer. 

The addition of a trailer fin helps improve control and maneuverability, particularly in larger or more powerful waves. By adding extra grip to the tail of the board, it stabilizes the ride without drastically altering the board’s overall feel. This setup allows the surfer to maintain a lively, responsive board while also benefiting from the increased stability the trailer fin provides.

One key benefit of using a trailer fin is that it can enhance the board’s speed and flow. The twin fin setup naturally encourages a more free-flowing, loose style of surfing. The trailer fin adds a touch of control, which is useful for bigger turns and carving. Surfers can still enjoy the fluidity of twin fins but with a bit more security in the tail.

Additionally, a trailer fin can help maintain the board's balance during high-speed maneuvers. It reduces the risk of the tail sliding out, which is especially important when surfing fast, powerful waves. While the trailer fin doesn’t drastically change the dynamics of the twin fin setup, it fine-tunes the performance for more controlled, consistent rides.

In short, a trailer fin adds subtle control and stability, enhancing the performance of a twin fin setup for a smoother and more confident ride.
