QUAD REARS Med-L FUTURES FINS (2) | ALPHA

The QD2 4.0 Alpha is a medium size Balanced quad rear with a Ride Number of 6.5. Alpha's C6 composite material is carbon and air infused making it lighter than Honeycomb. The responsive flex characteristics of C6 combine with the neutral QD2 template and symetrical foil make this set ideal for pairing with your favorite front fins, creating the ideal Quad option. All Alpha products are designed and manufactured exclusively in Huntington Beach, California.

SIZE: Medium-Large (145lbs - 195lbs) (65kg - 88kg)

REAR FINS:

HEIGHT:  4.05" 
BASE:  3.87" 
AREA:  11.67"

SYMMETRICAL FOIL

Symmetrical foil rear fins on quads give a fluid consistent feeling that is predictable in all conditions and is enhanced on quads when the rear fins are placed closely together.

  • ALPHA | made with a special composite designed with the help of 3M. It's carbon and air infused, and it's super lightweight.

  • RIDE NUMBER 6.5 = BALANCED (All Around)

ALPHA
Molded carbon fiber made in Huntington Beach, California that delivers every bit of performance you’d expect from an upgrade fin at a Balanced Ride Number. Incredibly lightweight & resilient, Alpha is the first of its kind; created using one-of-a-kind materials and new technologies developed by Futures.
COMPOUND 6
CARBON & AIR INFUSED

We have developed a brand new material blend that is lighter than Honeycomb and the next step in innovation for Futures. Infused with the resiliency of carbon fiber and the lightness of air, this is the most advanced injection fin material ever created. Working with the talented team at 3M, we were able to combine two key features that make our exclusive material so impressive

CARBON INFUSED

LIGHTWEIGHT & RESILIENT
First, we infused carbon fiber which has a higher strength to weight ratio than fiberglass. By replacing fiberglass with carbon fiber, the Alpha line is more lightweight & resilient than your standard fiberglass or plastic injection fins.

AIR INFUSED

LIGHTWEIGHT & STRONG
Second, we infused air. Yes, air! With our friends at 3M, we were able to develop a one-of-a-kind composite material that creates air pockets in the fin to reduce weight without sacrificing structural integrity.

FLOW TEXTURE

DECREASED DRAG & FIN HUM
After testing various surface geometries behind a jet-ski, we found a 3D flow texture that controls the separation pattern and influences the boundary layer to reduce the hydrodynamic turbulent wake drag. The result is a more predictable and efficient flow with a significant reduction in the audible whistle heard while surfing called “fin hum.”

RE-DESIGNED FLEX

STABLE BASE. SPRINGY TIP
With the added resiliency & strength of carbon fiber, we were able to go back to the drawing board and restructure the profile geometry of our Alpha line. The strength of the fibers allowed us to modify the flex pattern by removing material from tip for more spring and adding it to the base for more drive.

MADE IN USA

HUNTINGTON BEACH, CALIFORNIA
The first fin born from our Morpheus project is ALPHA! We are proud to announce that all materials, molds, dimensions, and manufacturing processes were thought up, developed and produced entirely in the USA.
