KT Arc Strapless Pro Carbon

Parawing, Wing, Foil Assist, Prone.

No inserts. Even lighter. The most balanced surf-style parawing, wing, and stability focused midlength. Our thinnest and most responsive all-arounder with redesigned aero contours and deck.

Intro

The Arc Strapless is a parawing inspired design that serves as a more stable midlength for winging and foil assist. The Strapless version is significantly lighter and more nimble underfoot without compromising on construction strength. Compared to the Super K2, the Arc is slightly longer and wider, but significantly thinner, making pumping, turning, and everything in between more direct and responsive in the air and on the water. A new recessed cockpit deck and aero contours unlock more static stability, helping riders move from kneeling to standing in light winds or messy water. Once flying, these subtle concaves offer more leverage over the foil, so surf-style carves feel more controlled, swoopy, powerful, and pitch stable, while refined rail bevels minimize tracking on touchdowns and cut through chop like a hot knife through butter.

Feeling

Balanced all-around design for fast takeoff, stability, intuitive handling, and agility. The Arc is designed to feel stable for getting standing with the parawing, wing, or foil assist. The recessed deck helps you settle in, lowers your stance, and increases leverage like the tail kick 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 it easier to balance on the surface and through turns compared to downwind boards and narrower midlengths.

Speed

Optimized aerodynamics, hydrodynamics, and volume distribution help the Arc accelerate efficiently while retaining stability. The shape hides volume without giving up as much stability as a narrower midlength or downwind board, especially during kneeling starts and transitions to standing. Once flying, the thinner profile and deck contours keep the board responsive in the air and smooth through speed changes, with predictable recovery when the board skips off the water.

Description

No strap inserts = less weight. Unlocking even more agility and playfulness. Significantly lighter and more nimble underfoot.

The Arc is designed for riders who want a more stable and surfy midlength platform for parawing, winging, and foil assist. The outline provides glide and acceleration, while the recessed deck and concaves make low-end control feel settled and predictable in any conditions. Once on foil, the Arc feels direct and engaged. The recessed deck lowers your stance and increases leverage, making it easier to drive through snowboard-esque carves, load the foil, and commit to swooping turns without the board feeling thick or corky.

• Vent plug: Solid State vent plug, simple to use, immune to leaks and failures.
• Foil Assist: integrated 2.4 GHz tuned connectivity windows for Foil Assist systems.

Shape

Stable midlength outline tuned for acceleration, glide, balance, and agility. Slightly longer and wider than the Super K2, with a thinner standing area to keep the board light in the air and responsive to input. The recessed deck with concaves, bottom contours, and width increase stability at low speed and give more leverage over the foil once flying, supporting surf-style carving, low-speed acceleration, and more controlled surface tracking.

Highlights

Bottom

• Flatter, streamlined double concave displacement tri-plane hull tuned for minimal drag, rapid lift, clean touchdown recovery, and compatibility with foil assist systems.
• Softer, rounded feel on touchdowns and surface contact while keeping release fast and clean.
• Fast low-end acceleration for lighter winds and getting up on foil with parawinging.

Rocker

• Lower nose entry angles tuned for fast lift and faster recovery in light wind, weak swell, and underpowered conditions.
• Less bottom rocker yet more deck rocker keeps the stance level between front and rear foot: more comfort, more control, no awkward front-foot height or “nose down” feeling at speed.
• Slightly more tail rocker than the Super K2 adds clearance and leverage to push harder through swooping turns and for more pop, without sacrificing touchdown recovery.

Rails

• Super K2 inspired rail flow: almond through the aero nose, transitioning to a boxier tail section, then tapering into harder beveled tail edges.
• Designed to improve water flow and reduce drag, with minimal tracking when the board reconnects with the surface.
• Controlled rebounds on touchdowns.
• Easy to redirect cross-wind at low speeds and for takeoff.

Agility

Our surfiest midlength yet! Responsive in the air and easy to drive through turns. The thinner profile and lowered stance help the board feel more connected and responsive to push into the foil through arcing turns downwind or in the surf.

Construction

Pro Carbon construction prioritizes strength and stiffness at minimal weight. An extra lightweight EPS core is wrapped in a full carbon high-density exoskeleton and finished with biaxial and unidirectional carbon in a high-density sandwich for rigidity and impact resistance.

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

Pads

• Refined lightweight slotted traction.
• Maximum grip at reduced weight.
• Reduced thickness for improved board feel and control.

Track Boxes

• New in-house designed 14-inch reinforced, foil-specific Universal Track System.
• Puncture-resistant elevated channels for durability and compatibility across mast lengths and hardware types.

Size Guide

Riders can size down in volume compared to the Super K 2.

48 L – 5'4" x 18.75": the highest-performance Arc feel for riders prioritizing minimal volume and swing weight, also ideal for lighter riders seeking progression. Best suited to higher-wind parawing and winging, and for prone surf or Foil Assist riders who want the smallest stable midlength platform. Team sizing reference: Keith Teboul 68 kg, Logan Bediamol 77 kg, Kai Lenny 73 kg. Rider weight: 30 to 78 kg.

58 L – 5'6" x 19.25": the daily-driver Arc with more float and stability for moderate winds. Strong blend of low-end support and skateboard-direct response once flying; a reliable Foil Assist crossover size. Team sizing reference: Ryan Arzy 70 kg, Casey Hauser 73 kg, Otis Buckingham 83 kg. Rider weight: 60 to 90 kg.

68 L – 5'9" x 20": core Arc sizing that balances stability, performance, and agility. Ideal for parawing progression and winging in mixed conditions; strong for Foil Assist sessions when you want confidence without going to a wider high-volume board. Team sizing reference: Adam Lewis 82 kg, Kane de Wilde 87 kg. Rider weight: 70 to 90 kg.

78 L – 5'11" x 20.75": more low-end stability without feeling oversized. A strong crossover size for winging, parawing, and Foil Assist; easier starts and more settled control in chop, while still thin and responsive through turns and transitions. Rider weight: 70 to 90 kg.

88 L – 6'2" x 21.25": high-stability performance midlength for intermediates, heavier riders, or lighter winds. Supports confident kneeling-to-standing progression for parawing and Foil Assist while keeping the surf-style carving feel; ideal for light-wind winging and parawing crossover. Team sizing reference: Elliot Leboe 91 kg. Rider weight: 75 to 95 kg.

98 L – 6'4" x 21.8": the maximum-stability Arc for the easiest starts and the most confidence in light conditions. The most supportive platform for parawing, winging, and Foil Assist progression, especially in light wind and chop, without turning into a full beginner shape. Rider weight: 80 to 115 kg.
