• Recommended for all board types. Best suited to performance and hybrid shortboards.

Fin Family

• Carver: Find Power. Powerful, drawn-out turns with added hold.

We haven't a chance to try this fin ourselves yet - but we had to get one in to check out. In the flesh, these fins don't disappoint. Featuring unique templates each fin is a piece of engineering beauty.

What they say:

'The H4 looks and surfs different from any other fin. Precision Swiss engineering matched with a highly evolved template provides an unprecedented level of control and predictability at high speeds.'

UNIQUE TEMPLATE

Radically different side & centre fin templates create a powerful fin set with ultimate speed & drive.

SIDE FIN PROFILE: Lower section produces maximum acceleration, while hatchet like tip creates stability & control.

CENTRE FIN PROFILE: Highly raked elliptical outline reduces drag, and offers feeling of predictability when releasing through turns.

FIN FOILS TEMPLATE: Thicker base with tapered tip optimises flex & regulates the release of energy during rail to rial transitions.

Ideal Conditions

A wide range of conditions, particularly good in critical overhead waves.

Board Types

Designed to fit the FCS II Fin System.

Recommended for performance shortboards with moderate-to-low rocker.

The Akila Twin fin redefines the classic theory of the twin-fin design and shapes it into a more high-performance model. The Akila twin’s fibreglass material combined with a wide base and extra tall height gives this fin maximum drive, while the thinner tip offers release and spring off the top.

There is a reason this is the most iconic, functional and versatile single fin available...it works on just about anything! The Greenough 4-A has been our bread and butter for close to 40 years now, and is still the most popular single fin design there is.

A truly well-balanced fin...the full base coupled with the tapering, moderately flexible tip provides a solid amount of drive off the bottom, and an acute responsiveness through arcing turns. Designed for both speed generation and spending time surfing in the pocket, the 4-A is a fin that will hold when you need it to and release when the time is right.

As the predecessor to the 4A, this template is important. It was conceived in the early ‘70s, and is a direct descendent from the original Stage 4 that swept the surfing world. We offer this fin to be used as you see fit. Positive reports have come in from a wide range of applications.

We'll just say this is one of the most classic, fundamental designs of a single fin for longboards… ever!!

One of our timeless shapes. This design is mostly delegated to the 2+1 set up. There is no other fin combination that makes longboarding seem so easy. You will be making turns when and wherever you want. We recommend this fin for anyone that may want to start surfing on a longboard.

The Power Blade, another original George Greenough design, was created with the intention of pushing the boundaries of the modern-day single fin surfboard. Through meticulous material selection, endless hours of testing, design revisions, and a uniquely constructed flex pattern, the Power Blade now has the potential of rivaling the performance characteristics of the thruster.

Here, Marc Andreini summarizes the Power Blade's function... "Although the thruster took surfing to a higher performance level (following single fins) with more speed and quicker responsiveness, we lost a lot of flow, trim, deep bottom turning and down the line style that went with single fin style surfing.  Now we can take that style, and up the performance to match the speed and virility of the postmodern board without sacrificing the flow."

The most important design aspect of the Power Blade lies within its ability to flex and ‘twist-off’ at the ‘head’ of the fin. This attribute provides variable-tow, similar to how a thruster works, which allows the tail of the board to follow the nose and in turn produces drive. In some ways it acts like a fish tail, flexing and twisting back and forth creating propulsion based on direction and angle of attack. The narrow base permits for an extremely minimal amount of water pressure resistance, allowing for a significant amount of response, speed, and maneuverability within a single fin.    

The main challenge in successfully producing this design, came through the need to retain a very stiff and extremely strong ‘leg’ in order to support all the load on the 'head.' Through extensive research and testing we finally landed on an extremely unique lay-up combination of high-density epoxy and fiberglass materials that met the qualifications without suffering fatigue. Our Power Blade fins meet 3 different demanding requirements within a singular fin… stiffness where needed, flex, and the ability to twist.
