Best Twin Fin Sets of 2025

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. 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 in this review are grouped based on the available types and the best pairing for your board. Let’s dive into the best twin fin sets of 2025!

Tom’s Twin Fin History Lesson

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. This movement has inspired many professionals and amateurs alike. 

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.

Best Keel Twin Fin Sets

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, 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.

Rob Machado Too Fish Keel Twin Fin Set - $125

“Classic keel template that’s built to cruise” 

Our Take: The Machado Too Fish Keel is Rob’s new take on the classic keel design. This fin was designed with Firewire’s Too Fish model in mind 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. These are very similar to the old Machado Keel fins but have slightly less surface area, more height, and more curve out the back. These factors help the Too Keel fins work in a wider variety of fishes and twin fins surfboards.

FCS II Christenson PG Keel Fin Set - $120

“Retro template with performance attributes” 

Our Take: The FCS II Christenson PG Keel Fin Set is a high-performance twin-fin setup designed in collaboration with shaper Chris Christenson. Crafted from Performance Glass (PG), these fins are tailored for surfers seeking a balance between traditional feel and modern performance. They are best used on wider-tailed boards with little to no rocker.

Futures Fins Al Merrick Fiberglass Keel Twin Fins - $125

“A traditional keel shape with a modern rake and graduated tip to add performance”

Our Take: The Al Merrick Keel is Channel Islands' modern take on a classic design. The AMK boasts more rake than a traditional keel, which helps with drawn-out turns on the open face. The fiberglass construction gives the feeling of glass on fins. However, the graduated tip flex allows for modern surfing. Whether you want to rip or cruise, these are the perfect keels for you!

Futures Fins Rasta Keel Honeycomb Twin Fin Set - $140

“It’s like putting a fighter jet engine into a classic car” 

Our Take:  The Rasta Keel Honeycomb Twin Fin is the brainchild of the Twin Lord himself, Dave Rastovich. The wide base and shallow height make the outline of this fin very similar to traditional keels of yesteryears. However, that is where the similarities end. The Rasta keels combine a V2 foil and flexible honeycomb construction, allowing you to take your classic twin fin to places you never imagined possible.

Futures Fins Mikey February Keel Fin Set - $130

“Signature fin of one of the most aesthetically pleasing surfers on the planet” 

Our Take: The Futures Fins Mikey February Keel Fin is brand new for 2025 and is a standout choice for surfers seeking to enhance the performance of their fish-style boards. Designed in collaboration with professional surfer Mikey February, this fin set offers a modern take on the traditional keel fin, combining classic characteristics with contemporary responsiveness.

Best Performance Twin Fin Sets

Performance twin fins tend to have a shorter base, are taller, and are usually 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.

NVS Album Apex Series Futures Compatible Twin Fin Set - $100

“Album Surfboards are renowned as some of the best high-performance twins out there. This fin was developed with that in mind”

Our Take: Designed by Matt Parker of Album Surfboard, the Album Apex is made for the radical twin fin surfing of Album team riders Josh Kerr and Asher Pacey. The large template offers ample hold in steeper waves with enough rake to generate speed and glide in smaller surf.

FCS II Power PG Twin Fin Set - $105

“Upright Twin that allows you to push harder of the bottom than most twins out there” 

Our Take: The FCS II Power Twin is a performance twin fin with a very high surface area. It is perfect for performance fishes that need to push hard through turns. The upright template, combined with the unique beak tips, allows this fin to perform at a high level.

Futures Fins Akila Aipa Twin Fin Set - $110

“A Twin Fin designed in Hawaii so you know it will work in some juice” 

Our Take: 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.

Futures Fins Britt Merrick BMT Twin Fin Set - $125

“Combines the best attributes of a traditional Keel and a performance Twin giving you endless possibilities on a wave”

Our Take: The BMT Twin Fin was developed and hand foiled by Britt Merrick of Channel Islands surfboards for their popular Twin Pin surfboards. The BMT is the most balanced twin fin as it sits somewhere right in the middle of a traditional keel and modern upright twin. You can expect loads of hold, drive, and release from these fins. This makes them ideal for not only fishes but narrow-tailed boards as well.

Best Twin + 1 Fin Sets

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.

Endorfins KS Futures Compatible Twin + 2 Fin Set - $140 “

“High Performance Twin Fin with multiple trailer options to allow you to expand the boundaries of what a Twin fin is capable of”

Our Take: The Twin + 2 is the latest addition to Endorfin's line of fins designed and tested by the goat himself, Kelly Slater. The twin fins are upright and support progressive surfing on any type of fish or shortboard in a variety of different conditions. What really sets this set of fins apart is the versatility of including two different trailer fins. The larger “stabilizer” trailer provides more drive and hold, while the smaller “guitar pick” trailer gives the board a more traditional twin fin feel while still providing a bit of stability. As with all Endorfins, these fins float!

FCS II Mark Richards PC Twin + 1 Fin Set - $125

“The Original Performance Twin Fin with an added trailer for stability” 

Our Take: Created by the master of the twin, four-time World Champion Mark Richard, the MR 2+1 is the perfect performance fin for any fish, hybrid, or shortboard. The fins are more uptight, allowing them to snap off the top easier than other twin fins on this list. These fins have a great balance of release and drive, while the added center fin ensures stability off the bottom. Go get radical!

Futures Fins Rasta Honeycomb Twin + 1 Fin Set - $145

“High Performance signature fin of one of the leaders in the Twin Fin Revolution” 

Our Take: Loosely based on the ever-popular T1 Twin Fin, the Rasta Honey Comb Twin + 1 has been tweaked to fit Dave Rastovich’s silky smooth style. The main difference is that the Rasta fins have a unique leading edge, which lends itself to smoother rail-to-rail transitions. Furthermore, these fins are infused with carbon fiber and jute in the honeycomb composition, creating more flex and durability.

Futures Fins T1 Alpha Twin + 1 Fin Set - $65

“Tried and true twin fin template at an affordable price” 

Our Take: The Futures Fins T1 Alpha Twin+1 Fin Set is a versatile and eco-friendly choice for surfers seeking a responsive, all-around twin-fin experience. The T1 Alpha features a neutral template with flat-foiled side fins and a symmetrical trailer fin, offering a lively feel and smooth rail-to-rail transitions.
