AERO Foil Handcrafted | CHS

Three Years, Three Podiums — A Proven Foil Champion

The CHS challenger Aero Foil line has brought CHS some of its greatest achievements in recent seasons:
World Champions in 2022, 3rd overall in 2023, and Vice World Champions in 2024 — all with different athletes.
This consistency confirms the aerodynamic efficiency and race-winning stability of the design.

But success doesn’t make us stop.
Our goal is clear: bring the world title back to CHS.

A Discipline That Demands Innovation

Foil requires a completely different aerodynamic approach compared to slalom.
Balance, leech behavior, gust absorption and vertical lift control become even more critical.
To stay ahead, innovation isn’t optional — it’s essential.

That’s why, after introducing the S-SHAPE profile across the CHS range, we developed a brand-new feature exclusively for foil sails:

The New S-Leech — Stability Through Intelligent Flex

The S-Leech is a revolutionary leech outline with a subtle S-curve unique to the Aero Foil 2025.

It allows:

• the top of the sail to remain less exposed and more stable

• progressive opening between battens 2, 3 and 4

• a more responsive leech in gusts that works independently without rider input

This reduces unwanted lift spikes, improves stability at speed and keeps the sail perfectly trimmed even in chaotic wind.

The result?
A foil sail that reacts intelligently to pressure changes — smoother, faster and more efficient.

Lower Center of Effort — More Control, Less Lift

By lowering the second batten from the bottom, the sail’s center of effort is also lowered.
This prevents the rider from being pulled upward during gusts — a common issue in high-power foil racing.

Benefits include:

• smoother foil flight

• better stance control

• reduced vertical lift in overpowered conditions

• a quieter, more neutral feeling on the hands

This translates directly into improved confidence and more speed on all courses.

Faster, More Stable, Less Vibration

Every design element of the Aero Foil 2025 contributes to:

• higher top speed

• enhanced gust stability

• dramatically reduced vibration transmitted through the foil

• more efficient acceleration and glide

Whether racing upwind, downwind or on technical reaches, the sail maintains locked-in composure and precise handling — exactly what world-class foilers demand.

For Riders Who Want Proven Results

The Aero Foil 2025 is ideal for:

• competitive foil racers (PWA, IFCA, national tours)

• advanced foilers looking for maximum stability

• riders who want a sail that works with them, not against them

• anyone seeking podium-level performance with intelligent aerodynamic behavior

A sail refined by champions — and built to win again.
