Twin Fin Fish Surfing: A Comprehensive Guide to the Retro Ride

The twin fin fish surfboard, a design born from the shortboard revolution, has enjoyed a resurgence in popularity. Embraced by surfers of all levels, from seasoned pros to weekend warriors, the twin fin fish offers a unique blend of speed, maneuverability, and retro cool. This article delves into the history, design, performance characteristics, and considerations for choosing the right twin fin fish for your surfing needs.

A Brief History of the Twin Fin Fish

The twin fin fish owes its existence to Steve Lis, a San Diego surfer and kneeboarder who pioneered the design in the early 1970s. Frustrated with the limitations of single-fin boards in smaller waves, Lis experimented with various fin configurations, eventually landing on the iconic twin-fin setup. His initial designs featured a wide tail with a deep swallow, providing increased surface area and bite in the water. The twin fin fish quickly gained traction among local surfers, who appreciated its speed and responsiveness.

During the late 1970s and early 1980s, the twin fin fish became a staple in many surfers’ quivers. However, with the rise of thruster (three-fin) boards in the early-to-mid 1980s, the twin fin fish gradually faded from the spotlight. The thruster offered a more stable and predictable ride, particularly in larger waves, leading many surfers to abandon the twin fin fish.

In recent years, the twin fin fish has experienced a significant comeback. Surfers seeking a more playful and engaging experience in smaller waves have rediscovered the joys of riding a twin fin fish. Modern shapers have refined Lis’s original design, incorporating contemporary rocker profiles, rail shapes, and fin placements to enhance performance.

Understanding the Design of a Twin Fin Fish

Several key design elements contribute to the unique performance characteristics of a twin fin fish:

Wide Tail and Swallow

The wide tail provides ample surface area for planing, allowing the board to generate speed easily in smaller waves. The swallowtail enhances maneuverability by creating two distinct points of pivot, making it easier to initiate turns. This combination of width and swallowtail gives the twin fin fish its distinctive look and feel.

Flat Rocker

Compared to high-performance shortboards, twin fin fish typically feature a flatter rocker profile. This flatter rocker further enhances planing speed and allows the board to glide effortlessly across flat sections of the wave. However, the flatter rocker can make the board feel less responsive in steeper or more critical waves.

Twin Fin Placement

The placement of the fins is crucial to the performance of a twin fin fish. Typically, the fins are positioned further forward on the board than on a thruster, and they are often canted outwards. This fin placement provides a loose and skatey feel, allowing the surfer to generate speed and perform radical turns with ease. Experimentation with fin size, shape, and placement can significantly alter the board’s performance characteristics.

Rails

The rails of a twin fin fish are typically full and forgiving, providing ample buoyancy and stability. This makes the board easy to paddle and catch waves on. However, some shapers are now experimenting with more refined rail shapes to improve the board’s performance in more powerful conditions. [See also: Surfboard Rail Design: A Comprehensive Guide]

The Performance Characteristics of a Twin Fin Fish

The twin fin fish offers a unique surfing experience that differs significantly from riding a thruster or single-fin board. Here are some of the key performance characteristics:

Speed

The twin fin fish is renowned for its speed. The wide tail, flat rocker, and efficient fin setup allow the board to generate incredible speed, even in weak or mushy waves. This makes it an ideal choice for surfers who want to maximize their wave count and have fun in less-than-ideal conditions.

Maneuverability

Despite its speed, the twin fin fish is also surprisingly maneuverable. The swallowtail and twin-fin setup allow the surfer to initiate turns quickly and easily. The board feels loose and skatey underfoot, making it easy to perform radical turns and carve across the face of the wave. This maneuverability makes the twin fin fish a popular choice for surfers who enjoy experimenting with different lines and styles.

Loose and Forgiving

The twin fin fish is generally considered to be a very forgiving board. The wide tail and full rails provide ample stability, making it easy to paddle and catch waves on. The board’s loose feel allows the surfer to recover from mistakes easily. This makes the twin fin fish a great option for beginner and intermediate surfers who are looking to improve their skills.

Not Ideal for Large Waves

While the twin fin fish excels in small to medium-sized waves, it is not generally recommended for larger or more powerful conditions. The board’s loose feel and lack of drive can make it difficult to control in steep or hollow waves. In these conditions, a thruster or quad fin setup would be a more appropriate choice.

Choosing the Right Twin Fin Fish

Selecting the right twin fin fish depends on several factors, including your skill level, weight, and the type of waves you typically surf. Here are some considerations to keep in mind:

Size

As a general rule, you should ride a twin fin fish that is shorter and wider than your standard shortboard. This will provide ample volume for paddling and catching waves. A good starting point is to choose a board that is 2-4 inches shorter than your shortboard and 1-2 inches wider. However, it’s always best to consult with a knowledgeable shaper or surf shop employee to determine the optimal size for your needs.

Volume

Volume is an important consideration when choosing any surfboard, and the twin fin fish is no exception. More volume will make the board easier to paddle and catch waves on, while less volume will make the board more responsive. If you are a beginner or intermediate surfer, you should opt for a board with more volume. If you are an experienced surfer, you may prefer a board with less volume.

Fin Setup

While all twin fin fish feature a twin-fin setup, there are variations in fin size, shape, and placement. Experimenting with different fin setups can significantly alter the board’s performance characteristics. Larger fins will provide more drive and control, while smaller fins will make the board feel looser and more skatey. It’s worth trying out different fin setups to find what works best for your surfing style.

Construction

Twin fin fish are available in a variety of constructions, including polyurethane (PU), epoxy, and various composite materials. PU boards are the traditional choice and offer a classic feel. Epoxy boards are lighter and more durable, but they can feel more buoyant. Composite boards offer a blend of performance characteristics. The best construction for you will depend on your budget and personal preferences.

Conclusion

The twin fin fish is a versatile and enjoyable surfboard that offers a unique surfing experience. Its speed, maneuverability, and forgiving nature make it a great choice for surfers of all levels, particularly in small to medium-sized waves. Whether you are a seasoned pro looking to add some retro flair to your quiver or a beginner surfer looking for an easy-to-ride board, the twin fin fish is definitely worth considering. So, embrace the retro ride and experience the joy of twin fin fish surfing!
