Performance Range

High-performance fin range

This category of fin designs contains all of the templates we consider high-performance for next-level surfing.

All the templates in this category are CNC-machined from solid fiberglass and come in a MANGO color only, except for the BLACK center fins.

The supported fin bases are GEARBOX, DUAL TAB (only available on request), and FUTURES.

BW Series

This is the latest series to join our range of CNC fins. It is a new design that has been under development for the past year. Features our BLENDED-WING profile.

This brand-new design utilizes our BLENDED-WING tech to deliver a fin with remarkable performance.

This new design is a high-performance fin that handles various conditions. It features our PHAT FOILS and HOLOFOILS, with the FLIPTWO allowing for more efficient HOLOFOILS. In addition, extending the tip gives the fin a lot more feel later into the turn while also providing a better pivot point.

The main body of the fin is more wing-like than the typical fin, which allows it to generate lift efficiently and, thus, create forward momentum.

Due to how the FLIPTWO is implemented, the fin profile features a distinctive taper from the base to the transition to the flip. The FLIPTWO is, in turn, a lot thinner than our first-generation flips. We are minimizing the risks of cavitation. There is also a slight hollowing of the inside face of the flip to give it a little more bite during a turn.

A dedicated center fin design features even more prominent tips to provide greater holding power and feel in the water. In addition, the center fin has very distinctive foils that differentiate between the throat and blade of the fin.

Initially, the following templates will make up this series—BW-400, BW-500, BW-525, and BW-550. The remaining templates will be added later in the year.

F8 Series

This is the latest series to join our range of CNC fins. It is loosely based on the DV9 design but with an added tip extension. Most of the designs in this series also feature a slight flip in the tip, called the FLIPTWO.

XT2 Series

This is the next-generation version of our XTC RTM fins. These new designs build on those excellent fins by adding improved foils and the FLIPTWO tips.

The primary driving force behind these fins is to deliver a design that behaves more like a wing than your typical "dolphin fin" style surfboard fin. The goal of this design was to modernize and enhance the original XTC.

The templates have been slightly modified at the base of the trailing edge in order to facilitate CNC machining the fins.

Like many modern wings, this design features a tip extension to enhance the fin's performance. This extension is flipped 12º to the outside and has a slight hollow foil on the inside face. The body of the fin also features a strong hollow foil. These fins are very efficient and fast, with a ton of drive. These improved flip tips are called the FLIPTWO. They also have the uncanny ability to help the board move through dead spots on the wave.

Due to their upright nature, they turn exceptionally well without losing speed through the turns. The tips play a crucial role in turning as they allow for the fin's transition during a turn. As the board is placed further on its rail, the tip of the fin becomes more vertical in the water, allowing it to create a pivot point. It's hard to describe but can be easily felt when using the fins.

Two combinations can be created for thrusters: the XT2-425 / F8-438C for a smaller, looser setup and the XT2-500 / F8-438C combo for much more drive and hold. Due to the shape of the center fin, it has a lot of hold when positioned further forward while still providing excellent turning ability due to the more upright nature of the fin's body.

These fins have been ridden on boards ranging from small fish and kneeboards to guns and towboards. They have successfully surfed in everything from 3' slop to 40' faces. They work!

A4C Series

The A4C series has undergone extensive testing before being put into production. This testing process resulted in many refinements and improvements to the series, easily making them the most versatile fins in our CNC range.

This series also has a wide range of sizes. These sizes cover a broad spectrum of fin combos, from twinzers to thrusters.

The A4C is a combination of our original A3 and XPD2 designs. We combined the best characteristics of the two into a fresh design that would eventually replace these older designs. We added several different sizes to make this series as versatile as possible.

The shape of this series features a strong cutaway at the base and a reverse curve in the upper portion of the tip, adding more tip area. The trailing edge of the fin is shaped like an "S" in profile to control better the water flow off the trailing edge of the fin. This aspect is similar to the XPD2; all these features have been enhanced. Coupled with the PHAT FOILS, it further enhances the water flow on and off the fin.

The consensus is that these fins are total winners for the general consumer as they are easy to get your head around and don’t have a lot of visually unusual shapes. Of course, once you start looking closer, there is much more going on than your typical dolphin fin, but the more conventional shape makes them much more approachable for the average surfer. This is a good thing in our minds as it will attract more people to try something different, and once they do, they will be blown away.

Two of the primary fins in this series recently received a redesign. The A4C-500 and A4C-550 have been modified to use the new BLENDED-WING profile for a more significant performance boost. This type of foiling bends the fin's profile just over halfway up. It allows the tip to be thinned out, improving flex and enhancing the inside foils. After extensive testing, we are convinced these are an improvement over the originals.

The addition of the A4C-500CK KAHI center fin has also enhanced the versatility of this series. These center fins are a game-changer in a thruster setup, allowing it to feel and behave much more like a quad. They maintain speed through turns and add looseness without losing holding power!

This new series' fins feature our PHAT FOILS and HOLOFOILS and are available with GEARBOX, DUAL TAB (on request), and FUTURES bases.

The A4C-500 and A4C-550 will be replaced by the newer A4C-500BW and A4C-550BW designs, incorporating our BLENDED-WING foiling technology. In the interim, both options remain available.

A4C BW Series

The A4C BLENDED-WING fins are replacement designs for the A4C-500 and A4C-550.

These new designs refine the existing templates by slightly adjusting the outlines at the cutaways.

The primary distinction lies in the incorporation of the BLENDED-WING feature. This feature introduces an outboard bend in the fin, positioned just above the midpoint from the base. This modification brings about several performance improvements.

Firstly, it reduces the fin’s tip thickness and enhances its flexibility. Secondly, it divides the fin into two distinct sections, with the lower half providing the initial drive into a turn, while the upper half provides the drive out of the turn. Lastly, it optimizes the HOLOFOILS on the inner faces, thereby augmenting efficiency and speed.

These two sizes are replacements for their equivalents in the A4C series. We highly recommend these over the originals; they are just way better.

New for 2025, we are adding a 6.00" version for the ultimate twin fin setup.

This series utilizes the same center fin as the A4C series, specifically the A4C-500CK.

WTF2 Series

The latest iteration of our classic WTF fin is now available for the first time as a CNC fin, with a slightly updated design.

One of the most unique fins in our range has been the WTF, which was only available as a molded fin. Now, we have updated the design so it can be custom-made.

The main changes from the original design were lengthening the blade slightly and narrowing the throat slightly to make it more wing-like. The original version had a double bend when viewed in profile. This revised design employs our BLENDED-WING concept to smooth out the fin, making it easier to produce.

Its improved flex allows it to spring back more in turns. As with the original, it features a narrow base for turning ability.

The WTF2-425 is the only size in this series. It is an excellent back fin for a quad setup and can be used with almost any of our larger front fins. It adds improved hold and extra drive to any quad setup. Some people like to use it as a canard fin in a twinzer or reverse quad setup, where it excels due to the BLENDED-WING.

It also makes for an excellent side fin in a 2PLUS1 setup.
