CHS Ikaros S1 — Wing

The CHS Challenger Ikaros S1 represents a new benchmark in high-performance wing design. Developed by CHS sail designer Claudio Badiali, it was engineered with the same philosophy and technical ambition that define CHS windsurf sails on the PWA World Tour: precision craftsmanship, advanced materials and race-proven aerodynamic efficiency.

To achieve this, the Ikaros S1 features:

• a full Aluula Leading Edge and bladder for maximum rigidity and ultra-light weight
• a differentiated-fabric canopy for ideal tension and durability
• a single carbon bar for direct, responsive handling
• flat valves, optimized weight distribution and a fully padded wing bag
• a refined new shape born from over a year of prototyping

Every detail was tuned through intensive testing with elite riders in Porto Pollo (Sardinia) and La Palme (France) — including feedback from the “Prince,” Andrea Baldini, and top speed athletes. Riders immediately praised its stability, maneuverability, gybe control and exceptional acceleration.

A World-Record Proven Wing

The Ikaros S1 made its official debut at the
2025 Prince of Speed ISWC World Championships in La Palme,
and the results spoke for themselves:

Audrey Marie Agnes, riding a pre-series Ikaros S1, achieved:

• Top speed: 33.6 kts
• World Record 500 m: 30.99 kts
• World Record Nautical Mile: 29.40 kts
  (records pending WSSRC ratification)

A stunning validation of over a year of design, testing and refinement.

For Riders Who Want the Absolute Best

The Ikaros S1 delivers:

• ultra-light handling
• exceptional stability in high-speed runs
• effortless power delivery
• precise control in gybes
• unmatched top-end velocity

It is a wing built for riders who demand excellence — and for those chasing pure performance on the water.

The Ikaros S1 isn’t just a new wing.
It’s the arrival of a world-class speed machine, handcrafted in Italy and already etched into the record books.
