KT Foil Apex Ultra High Modulus Carbon Mast- Foils Each size of the Apex is engineered from the ground up around the demands of its specific discipline.

FULL DESCRIPTION

Each size of the Apex is engineered from the ground up around the demands of its specific discipline. The result is a mast that responds exactly the way you need it to, faster, cleaner, and more confidently, no matter how hard you’re pushing your riding.

A forward offset, multi air foil profile is tuned for submerged efficiency and ventilation resistance, while minimizing spray drag during surface contact. The aggressive taper comes from extensive video analysis of how riders engage different mast zones across disciplines and conditions, then refined through flex pattern mapping and airfoil optimization. The payoff is a mast that stays composed through chop, resists ventilation when you’re pushing hard, and delivers a clean, connected feel that lets you ride with total confidence.

The Apex series stands apart because every mast is designed independently from the ground up. Each size gets its own sectional variation, taper, and performance priorities not a scaled up or scaled down version of a single profile. That allows the 77 to focus on unpowered speed, glide, and maneuverability for downwind racing, performance surf, and wake foiling. The 85 is tuned as the allrounder for wing foiling, wave riding, and freestyle control, while the 95 is built for highspeed wing powered riding where ventilation resistance, stability through chop, and control at deep lean angles or in big waves matter most.

Across the lineup, the mast uses multiple airfoils along the span, each tuned for low submerged drag, strong ventilation resistance, and minimal spray drag during surface contact. Designed by Kane de Wilde, the leaner leading edge with thickness carried farther back helps the mast pierce the surface more cleanly, reducing spray and keeping the ride smoother and quieter.

Above the waterline, Apex incorporates a forwards wept design for structural reasons, aligning the carbon fiber with the down and forward load path riders generate while winging. This reduces twist and improves efficiency through the baseplate zone, keeping the mast feeling solid and predictable under heavy load. The trailing edge stays close to vertical with a subtle taper toward the bottom for clean release and stability.
All sizes feature a forward offset baseplate to reduce swing weight and create a more direct, connected feel to the foil. The updated baseplate fairing blends more cleanly into the plate, lowering drag for smoother touchdowns and quicker, more efficient takeoffs.
