KT Arc Pro Carbon

Arc

The Arc is a parawing-focused board that also serves as a more stable midlength for wing and Foil Assist. Compared to the Super K2, it's slightly longer and wider, but noticeably thinner, making it much lighter and more responsive in the air. The recessed cockpit deck and concaves provide significant static stability, helping riders transition from kneeling to standing in light wind or choppy water. Once airborne, these subtle concaves offer more leverage on the foil, making surf-style carves more controlled, fluid, powerful, and pitch-stable.

Sizes: Available in 48 / 5'4″, 58 / 5'6″, 68 / 5'9″, 78 / 5'11″, 88 / 6'2″, 98 / 6'4″ (liters / feet).

Colors: Available in bright vivid red over marbled silver with black logos. Ultra-lightweight, high-durability enamel paint finish for reduced weight and better waterproofing.

The most balanced surf-style parawing and wing-oriented midlength board. With a slightly wider, more rockered recessed deck, narrower offset strap options, and a streamlined outline for smooth, arcing turns.

Feel

Balanced design in every respect for quick takeoff, stability, intuitive handling, and agility. The Arc is designed to deliver a stable feel when standing up on parawing, wing, or Foil Assist.

The recessed deck helps you settle in, lower your stance, and increases leverage — like the kicktail of a skateboard — allowing you to push harder into the foil.

The thinner profile keeps the Arc responsive in the air, while the wider platform makes balancing on the surface and in turns easier, compared to narrower downwind boards and midlengths.

Speed

Optimized aerodynamics, hydrodynamics, and volume distribution help the Arc accelerate efficiently while maintaining stability. The shape hides volume without sacrificing as much stability as a narrower midlength or downwind board, particularly during kneeling starts and transitions to standing. Once airborne, the thin profile and deck contours keep the board responsive in the air and smooth through speed changes, with predictable recovery when the board touches down on the water.

Description

The Arc is designed for riders looking for a more stable, more "surfy" midlength platform for parawing, wing, and Foil Assist. The outline delivers glide and acceleration, while the recessed deck and concaves make low-speed control stable and predictable in all conditions.

Once airborne, the Arc delivers a direct, engaged feel. The recessed deck lowers your stance and increases leverage, making snowboard-style carves, loading the foil, and committing to turns easier without the board feeling thick or soft.

Vent Plug

Solid State vent plug that eliminates failure points and leaks typical of Gore-Tex style systems.

Shape

Stable midlength outline, tuned for acceleration, glide, balance, and agility. Slightly longer and wider than the Super K2, with a thinner stance area to keep the board light in the air and responsive to pumping. The recessed deck with concaves, hull contours, and width increase low-speed stability and provide more leverage on the foil once airborne, favoring surf-style carves, low-speed acceleration, and better on-water tracking.

Construction

Pro Carbon construction prioritizes strength and stiffness for minimal weight. An extra-light EPS core is wrapped in a full high-density carbon exoskeleton, then finished with high-density biaxial and unidirectional carbon sandwich layers for stiffness and impact resistance. Integrated fiberglass windows, tuned to 2.4 GHz, support Foil Assist connectivity.

• Nearly 20% lighter than standard carbon construction
• Extra-light EPS core wrapped in a multilayer high-density carbon exoskeleton
• Full high-density biaxial and UD carbon sandwich for maximum stiffness and impact resistance
• Integrated fiberglass windows tuned to 2.4 GHz for Foil Assist connectivity

Pads & Straps

• Lightweight, refined textured traction
• Maximum grip for reduced weight
• Reduced thickness for better board feel and control

Includes adjustable front and back MFC footstraps, adjustable from the inside, with hardware.

• Surf-style insert pattern with slight offset options for centered, balanced directional riding, reducing heelside bias and keeping alignment over the foil
• Closer strap insert increments (½ inch) for more adjustability
• Centers stance and center of mass over the board and foil, rather than loading weight too far toward the heel side as in traditional slalom or wingfoil race patterns
• Straps offer a more locked-in, powerful feel in carves, more control in jibes, and now snowboard-style narrow stance options

Track Boxes

New universal 14" track system.

• In-house designed, reinforced 14-inch foil-specific track boxes
• Raised, puncture-resistant channels for durability and compatibility with different mast lengths and hardware types
