Best Twin Fin Sets of 2023

Best Twin Fin Sets of 2023

Initially designed for the swallow-tailed fish surfboard, twin fins give surfers the feeling of freedom without the predictability of a center fin. With no trailing fins to hold it back, the two extra-large fins give a surfboard just enough stability, allowing you to draw completely different lines than a thruster, quad, or single fin. Currently, twin fins are often paired with a plethora of different shapes from the classic fish, twin pins, mid-lengths, and even high-performance shortboards.

Today, nearly every surfboard shaper offers a twin fin design. At Cleanline Surf, we have a twin fin for every board and every ability. The fins are grouped based on the available types and the best pairing for your board. Let’s dive into the best twin fin sets of 2023!

Tom’s Twin Fin History Lesson

Variety of different twin fin sets: twin + 1, performance twin fins, and keel twin fins.

Years ago, our former in-house surf historian, Tom, wrote a piece about the history of twin fins. In short, twin fins have been around in some capacity since the 1940’s where Californian surf legend Bob Simmons experimented with double-keel fins on his signature Mini Simmons shapes. Shortly after, creative geniuses such as George Greenough from Santa Barbara and Steve Lis from San Diego began discovering twin fins' limitless potential on their kneeboards.

Throughout the 70’s twin fins were the preferred configuration of professional surfers. No one embodied this revolution like Mark Richards, who won four consecutive world titles (‘79-’82) riding his signature MR Twins. However, it was short-lived. In 1980 MR’s fellow Australian Simon Anderson developed the “Thruster,” and twin fins quickly became an afterthought and were thrust into surfing obscurity.

Since the 80’s there have been brief resurgences of the twin fin. Lost’s 1997 movie “5’5” 19 ¼” centered around San Clemente shaper Matt Biolos’ Round Nosed Fish design that was a performance-infused homage to twin fin designs of yesteryears. More recently, surfers such as Dave Rastovich and Asher Pacey have sparked a two fin renaissance redefining what is possible on a twin fin. Many professionals and amateurs alike have been inspired by this movement.

Today retired professional tour surfers such as Josh Kerr, Joel Parkinson, and 3X world champion Mick Fanning choose twin fins over thrusters. It all comes back to the freedom to draw unique lines that don’t necessarily fit the professional judging criteria.


Keel Fins

Keel fins are the original twin fin with roots tracing back to Steve Lis’ San Diego Fish revolution of the 60’s. Best paired with a traditional wide fish outline, keel fins have a longer base and are often shallower in depth than some of the other twin fins on this list. The template gives the board insane down-the-line speed and carving ability on open faces. If you are a traditionalist looking for a pure twin fin feeling, then a keel fin set is the way to go. However, it’s important to note that these fins tend to “slide out” more on steep waves, especially when trying to surf more vertically.


Jeff McCallum Keel Twin Fin Set

"Traditional Style"

McCallum’s fin set is what I would call a modern keel. It keeps the old-school outline of a traditional keel but is more upright than other keels featured. The slightly upright design gives it a more high-performance feel.

The Machado Keel is Rob’s take on the classic keel design. This fin was originally designed for his popular Firewire Go Fish model and is excellent for down-the-line speed and long-drawn-out carves. The fiberglass construction combined with the flat foil makes these fins feel as close to “glass on” fins as possible.

"Twin Pin Master"

Performance Twins

Performance twin fins tend to have a shorter base, are taller, and usually are more upright. The design allows the board to surf more vertically and gives it more hold in better conditions. You still get the down-the-line speed but can have more confidence that the board will hold when bottom turning aggressively. These fins are perfect for performance fishes with a narrower outline and tail versus a traditional fish.


Akila Aipa Twin Fin Set

"Great For More Drive"

Akila Aipa Twin Fin Set

The Akila Aipa is a true high-performance twin. The template still has a wide base and extra height, giving the fin maximum drive. The fin also incorporates a thinner tip which offers release through turns and carries speed through maneuvers.

Twin + 1

Though technically not a twin fin, the Twin + 1 setup deserves a spot on this list for its popularity and versatility. The setup is almost a subgenre for performance twins since there aren’t many keel Twin + 1’s. With the addition of the small center fin, it gives all the benefits of the performance twin with even more stability. It’s almost like putting training wheels on your twin and offers the ability to get the feeling of a twin fin on boards you wouldn’t usually be able to. Because of its versatility, the twin + 1 works on various boards, from fishes to performance shortboards.

T1 Honeycomb Twin + 1

The Futures Fins T1 Honeycomb Twin + 1 is a twin-fin design for down-the-line speed, drive, and easy rail-to-rail transitions synonymous with modern twin-fin surfing. The honeycomb construction creates a medium flex pattern, providing a softer feel than fins made from solid fiberglass. This helps to create lift and drive even when the waves lack power and steepness. The T1's are also available in Alpha and Thermotech construction for surfers on a budget.
