121 cm².

The most lively and carvefocused option in the lineup. It feels sharp, reactive, and instantly engaged, built for riders who want maximum responsiveness and a short, surfy feel while still keeping pitch control locked in. The carbon layup lets you run it smaller than noncarbon tails for the same lift, cutting drag and giving the ride a crisp, controlled edge. Best paired with smaller to midsize front wings when you want looseness and agility without losing confidence or precision. Common frontwing matches:

• Halo – Ideal with 550 Surf, and great when you want the loosest, most reactive Halo feel
• Loosens up bigger front wings like the 800 and 950
• Solus – Ideal for 565 to 775 for cruising and turns
• Atlas – Pairs well with the 570 and 680 for surforiented riding
• Nomad -700 and 830 surf and cruise

141 cm².

A balanced, doeverything dailydriver size that feels smooth, lively, and composed. It keeps the surfforward character of the Atom but adds extra stability for choppier water, winging, or slightly heavier riders. When you want maneuverability without giving up control, this is the size that stays predictable, responsive, and confidenceinspiring in all conditions. Best paired with midrange front wings across most families, delivering a clean blend of looseness, stability, and allconditions versatility. Common frontwing matches:

• Halo – 550 to 800, both cruise and surf setups
• Solus – 650 to 1110 cruise, depending on rider weight and conditions
• Atlas – 570 to 960 surf and cruise
• Nomad -700 and 830 surf and cruise
• Instinct – ideal progression and advanced pairing once riders step down from the learning tail

161 cm².

The stability oriented option in the Atom family, the 161 feels calm, planted, and composed. It smooths out speed changes, chop, and transitions with extra pitch damping while still keeping that signature surf connected Atom feel. This is the size you reach for when you want control and confidence at higher speeds or in mixed, messy water without losing the intuitive responsiveness that makes the Atom so fun to ride. Best paired with mid to larger size front wings, or any setup ridden fast in variable conditions where stability becomes a performance advantage. Common frontwing matches:

• Halo – 550 to 950, especially when you want added surf and freestyle stability
• Solus – 930 cruise setups
• Atlas – 790 to 1130 surf, and a strong choice when conditions get unpredictable
• Nomad – 830 to 980 surf and cruise

181 cm².

Feels planted, predictable, and confidencebuilding. It delivers the most pitch damping and forgiveness in the Atom Surf range, giving you a calm, settled ride through speed changes, chop, touchdowns, and highimpact moments. The foil tracks cleanly, holds composure when pushed, and gives you steady, intuitive feedback that makes bigger wings, heavier riders, and learning environments feel smoother and more controlled. Best paired with larger platforms or higherimpact riding where stability becomes a performance advantage. Common frontwing matches:

• Halo – 950 Halo locked in stability
• Atlas – 1130 and 1340 surf setups
• Nomad – 980 and 1160 cruise and surf
• Instinct – 920 through 2200 for intermediate cruising

The Atom adds flow, responsiveness, and that effortless “surf connection” that makes every turn feel natural.

The Atom Surf Tail is built around a simple idea: control creates performance. Instead of chasing maximum glide or racetail efficiency, Atom focuses on giving riders a more intuitive, connected feel with the foil, where every input translates cleanly and predictably. The carbon construction lets you run a smaller tail while keeping the same lift, cutting drag and sharpening response. Setups feel shorter, lighter, and easier to place through turns, whitewater hits, freestyle moves, and landings. Everything becomes more reactive without becoming twitchy. Atom Surf pairs seamlessly across the entire KT frontwing lineup. On surforiented wings like Nomad and Halo, it tightens turning and adds a loose, skateinspired feel. On faster wings like Solus or Atlas, it boosts maneuverability and confidence without overpowering the wing’s natural speed and glide. It enhances the character of each wing rather than changing it, giving riders a more controlled, more expressive ride across every discipline. Carbon, surforiented tail built for a lively, connected feel on the water. Shim-tunable to dial in stance, fuselage length, and frontwing pairing for your preferred balance. Designed to unlock a looser, more playful ride without giving up the control and precision that keep you confident at speed and through maneuvers.
