Futures Fin Alpha Vector 3/2: The #1 Fin for Explosive Surfing Power
Futures Fin 3/2 – Speed, Control & Innovation for Hawaiian Surf
Experience next-level rail control, speed, and maneuverability with the Futures Fin Vector 3/2 Alpha. Engineered for power surfers, technical turns, and high-speed lines, this fin is redefining modern surf performance in Hawaii and beyond.
Speed Generating – Unleashing Performance in Hawaii's Waves
The re-release of the Futures Vector Fin 3/2 in the Alpha construction brings serious excitement. Originally released in 2006, this advanced foil and tip configuration setup is purpose-built for surfers chasing down the perfect blend of flow, speed, and responsiveness.What is a Scimitar Tip – And Why It Matters
The Scimitar Tip design cuts the trailing edge flat, reducing the template's overall length. This tightens the turn arc and creates sharper release, especially useful when transitioning out of powerful carves.
This unique shape complements the 3/2 foil by allowing the fin to flex and recover in a way that feels springy, yet controlled — delivering extra boost during maneuvers.
What is the Vector Foil?
The Vector is a Futures-exclusive concave foil that increases water attachment. In the Vector 3/2 model, this foil runs the full height of the fin, from base to tip. This encourages laminar flow, improves lift, and reduces drag throughout turns.
What Does 3/2 Mean?
The "3/2" refers to an extra 3° cant and 2° toe-in in the upper section of the fin. At the base, you’ll find a standard 6.5° cant. But as you move toward the tip, this increases to 9.5°, creating a twisting effect that allows for better planing angles in turns. The result? More drive, deeper hold, and explosive exit speed.
Scimitar Tip Design:
The Scimitar Tip, characterized by its flattened trailing edge, reduces the fin's template length. This design tightens the turn arc, complements the 3/2 foil's lift and speed, and enhances the feeling of release from turns .
Real-World Performance in Hawaiian Waves
In steep reef setups and powerful beach breaks across Hawaii, the Scimitar 3/2 holds its own — and then some. Test riders report enhanced hold during deep bottom turns and a faster transition between carves. Whether threading barrels or laying down hacks, this fin responds instantly.
In smaller surf, the concave foil helps maintain speed, which is especially beneficial when waves lack push. That makes the Scimitar a versatile tool — not just for performance boards, but for grovelers and hybrids too.

Alpha Construction: Light, Tough & Eco-Conscious
Futures' Alpha construction uses a carbon-infused composite called NetPlus™ made from recycled fishing nets. This material is both eco-responsible and high-performance. It’s light enough for sensitive feel yet strong enough to last through heavy Hawaiian surf seasons.
Alpha fins are crafted using 3D-printed molds for accuracy and consistency. So every Scimitar 3/2 fin delivers performance exactly as designed.
How Does the Vector 3/2 Compare to Other Fins?
Compared to standard thruster setups, the Scimitar 3/2 offers more lift and less resistance. The concave foil behaves differently from traditional flat or inside-flat foils — creating drive by channeling water and reducing cavitation. This results in smoother arcs, less tail slip, and more consistent release under load.
Setup & Compatibility
Fits any surfboard with a Futures fin box. Installation is easy — simply slide in, tighten with a fin key, and you're ready to go. We recommend pairing with high-performance shortboards, step-ups, or hybrid grovelers.
Fin Maintenance Tips
- Rinse with freshwater after every session to prevent salt buildup.
- Check base and screw tightness regularly to avoid loss or damage.
- Store out of direct sun and extreme heat to avoid material fatigue.

Frequently Asked Questions (FAQs)
What makes the Futures Scimitar 3/2 fin different from other thruster fins?
The Scimitar 3/2 uses Futures’ Vector foil and an exclusive 3° cant + 2° toe-in configuration that adds speed through turns. The cut-off Scimitar tip improves release, while the concave foil boosts water attachment and lift for powerful maneuvers.
Is the Scimitar 3/2 good for small waves?
Yes, the Scimitar 3/2 generates speed even in softer conditions. The Vector foil increases water flow and projection, which helps surfers maintain momentum in weaker surf.
Does the Scimitar 3/2 work in bigger or punchier surf?
Absolutely. The deeper hold from the 3/2 foil design and Scimitar tip provides drive and control in steep faces and heavier surf, making it suitable for Hawaiian reef breaks and larger waves.
What boards are best for the Vector 3/2?
This fin performs best in performance shortboards, step-ups, and high-performance grovelers. It fits any surfboard with a Futures fin box system.
How do I install the Scimitar 3/2 fins?
Slide the fins into your Futures fin boxes and secure them using a fin key and set screws. Always double-check for tightness before paddling out.
What is the Scimitar Tip and why is it important?
The Scimitar Tip is a flat-cut trailing edge that tightens the turn arc and allows for faster fin release out of maneuvers. It makes the board feel looser and snappier without losing hold.
What materials are used in Alpha construction?
Alpha fins are made from a lightweight carbon-infused composite that includes NetPlus™ recycled fishing nets, offering eco-conscious durability and precision performance.
Will this fin work for beginners?
It’s more suitable for intermediate and advanced surfers. Beginners might not yet notice the subtle performance benefits of the Vector foil or Scimitar tip but can still ride them without issue.
How do I clean and care for my Scimitar 3/2 fins?
Rinse with freshwater after every session, store out of direct sunlight, and regularly inspect for cracks, looseness, or salt buildup at the base and screws.
