KT Arc Strapless Pro Carbon

KT Arc Strapless Pro Carbon – The Balanced Midlength for Parawing, Wing and Foil Assist

The KT Arc Strapless Pro Carbon 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. No strap inserts unlock even more agility and playfulness.

Feeling

Balanced all-round design for fast take-off, 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 settle in, lower 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

Optimised 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.

Design & Innovation

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 – surf-style carves feel more controlled, swoopy, powerful and pitch-stable, while refined rail bevels minimise tracking on touchdowns and cut through chop.

Shape

Stable midlength outline tuned for acceleration, glide, balance and agility. Slightly longer and wider than Super K2, with a thinner standing area. Recessed deck with concaves, bottom contours and width increases stability at low speed and gives more leverage over the foil once flying, supporting surf-style carving, low-speed acceleration and more controlled surface tracking.

Construction Highlights

Bottom: Flatter streamlined double-concave displacement tri-plane hull tuned for minimal drag, rapid lift, clean touchdown recovery and compatibility for 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 feeling level between front and rear foot – more comfort, more control. Slightly more tail rocker than Super K2 adds clearance and leverage for harder turns and 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 bevelled tail edges. Improved water flow and reduced drag with minimal tracking on touchdown reconnection. Controlled rebounds. Easy to redirect cross-wind at low speeds for take-off.

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 prioritises strength and stiffness at minimal weight – nearly 20 % lighter than standard Carbon construction. Extra lightweight EPS core wrapped in a full-carbon high-density exoskeleton, finished with biaxial and unidirectional carbon in a high-density sandwich for rigidity and impact resistance. Integrated fiberglass windows tuned to 2.4 GHz for Foil Assist connectivity.

Foil Assist & Technology

Integrated 2.4 GHz tuned connectivity windows for Foil Assist systems. Solid State Vent Plug – simple to use, immune to leaks and failures. New 14″ Universal Track System – in-house designed 14-inch reinforced foil-specific track boxes with puncture-resistant elevated channels for durability and compatibility.
