Designed for Maximum Efficiency and Performance

High Aspect Ratio Front Wing

At the heart of the Flow Lower Plane is the Flow Front Wing, Slingshots most efficient and high-aspect design to date. Featuring an aspect ratio of 11 across all sizes, this wing delivers maximum glide, low drag, and a broad speed rangegiving riders the ability to connect multiple waves, pump with ease, and carve powerful lines with minimal effort.

Flow Size Options

Each size is tailored to different riding styles:

• 600 Ideal for high-speed, tight turns, smaller riders, and high wind.

• 800 Balanced all-around performance with agility and glide.

• 1000 Ultimate pumping efficiency and downwind flow.

Performance-Driven Front Wing Features

The Flow Front Wing is more than just efficientit’s engineered for next-level control and power transfer.

Medium-High Camber Profile

Generates early lift and sustained flight, even at lower speeds, making the Flow versatile across wave size and energy.

Wing Tip Twist & Anhedral Shape

Reduces tip breaching while enhancing carving stability and roll control. The slight downward curve of the anhedral design provides extra grip during turns.

Tapered and Blended Profile

Smooth transitions and low drag at all speeds. The subtle tapering increases reactivity and complements the closer mast placement, giving riders a more direct feel underfoot.

Flare Stabilizer Low Drag, Maximum Response

Paired with the Flow front wing is the Slingshot Flare Stabilizera precision-tuned rear wing optimized for acceleration and control. With a high camber, high angle of attack, and short fuselage length, the Flare is Slingshots most reactive and efficient tail design to date.

Flare Tail Key Features:

• Aspect Ratio: 11 for ultra-low drag

• Camber Profile: High lift-to-drag ratio

• Angle of Attack:

  • Flare 145: -4.25 for max reactivity

  • Flare 175: -3.5 for more stability

Why It Matters:

• Shorter Fuselage = Tighter Turns The compact length brings the front and rear wings closer together, dramatically improving pitch sensitivity and carve response.

• Increased Pump Return The Flare tail provides a more elastic, springy feelideal for linking bumps and boosting acceleration during low-speed transitions.

• Less Drag = More Speed The narrow profile and swept-back design cut drag to a minimum, making it perfect for race, freestyle, and surf foiling.

One-Lock System Simplicity Meets Strength

The One-Lock latch system is Slingshots signature quick-connect technology that revolutionizes how riders assemble and break down their foils.

• Tool-free Installation

• Stronger Wing-to-Fuselage Connection

• Preinstalled for Ready-to-Ride Setup

Whether you’re switching out foils on the beach or tuning your setup for the session ahead, One-Lock gives you modular freedom without the hassle.

Built to Fly in All Conditions

Prone Foiling

The Flow/Flare combo is a dream for prone surfers. With long glide and efficient pumping, youll easily connect wave after wave, while the short tail fuselage gives you unmatched carve control.

Wing Foiling

Glide upwind, rip into turns, or pop airs with total control. The Flows speed range handles light breezes and overpowered gusts with equal ease, while the Flares acceleration helps you snap back into position after every maneuver.

Wake Foiling

Accelerate effortlessly behind the boat and enjoy tight, energetic turns without overpowering your legs. The low drag of the Flow front wing plus the instant feedback from the Flare stabilizer make wake sessions longer and more dynamic.

Downwind Foiling

When its time to chase open-ocean bumps, the Flow wings glide efficiency and lightweight carbon construction keep you flying farther with less effort. Paired with the Flare stabilizer, youll enjoy better pitch stability and smoother transitions across long distances.
