Phantom IRIS Windfoils

 

 

Phantom International is proud to introduce its FOILS LINE with the Iris R and F Windfoils.

After launching its Windsurfing sails line early 2018, it was a natural path to start working on windfoils. The Iris R and F Windfoils have been developed by Alex Udin, designed by Gonzalo Redondo D3 Applied Technologies, structured by Ellis Engineered, and tested by Alexandre Cousin, Thomas Goyard and Benjamin Tillier. It features the unique M40J high modulus and T700 carbon prepreg to guarantees unreached performances & stability

HIGH MODULUS oR T700?

Other major brands are announcing the use of high modulus prepreg carbon while in fact they are using “high strength carbon fiber” T700. The Iris R is the only windfoil on the market using M40J prepreg carbon which is the highest modulus Tensile to be featured in a windsurfing foil today. The Iris F is featuring a T700 Lay up.

< T700: High Tensile Strength (used with major windfoil brands)

> T700 a T1000: Intermediate Tensile Strength

> M30: High Modulus

Windfoiling components, especially masts, are made using various grades of carbon fibers characterized mainly by their tensile strength and tensile modulus. Tensile strength is the amount of force needed to cause the fibers to break, while the tensile modulus is a measure of the carbon fiber's stiffness.

The cost of the materials goes up with the increase in tensile strength, or increase in tensile modulus.

The chart below, drawn by Toray Industrial, illustrates some basic characteristics of the Toray range of carbon fiber prepreg, and illustrates why using multiple layers of various modulus carbon fiber is the only way to make high performance, safe and durable parts.

The use of the High Modulus allows a super stiff mast for explosive accelerations, amazing control and un compromised stability at high speed (above chart with the Iris R).

Developed by Alex Udin

 

Phantom International Founder Alex Udin started making sails at the age of 16. With a passion for sailing and windsurfing, he started working in R&D lofts in Maui back in 2001 and founded his sailmaking company in 2003, designing high performance sails for famous boatyards and professional sailors like Franck Cammas and François Gabart.

 

“Our main goal was to design the finest racing windfoil on the market with the help of our fluid dynamics and structure analysis experts from the America's Cup.

We have been working for several years in close collaboration with Gonzalo Redondo (D3 Applied Technologies) and Brett Ellis, both from the AC community (American Magic team, and Artemis).

The Ultimate Racing Windfoil is the result of many hours of testing and performance data collection, including GPS, cameras and gyros (speed, VMG, healing angle, pitching angle, leeway…).

These datas allowed us to have precise inputs to run some very accurate CFD (Computerised Fluid Dynamics) and (Finite Element Analysis) simulations in real conditions with professional windsurfer Benjamin Tillier.

CFD and FEA are powerful tools previously and exclusively used for the design of racing yachts such as the America’s Cup or Formula 1.

Through these simulations, we optimized and refined the shape and structure of the foil in every details, and reached significant improvements in the efficiency and performance”.

Designed by D3 Applied Technologies

 

D3 Applied Technologies was founded in 2012 by Gonzalo Redondo. Amongst other projects, Gonzalo has previously worked as a design engineer and CFD analyst for Groupama Sailing Team (Winner of the VOR 2011-2012), Puma Ocean Racing VOR70, Telefonica VOR70, and Artemis Racing Team, Challenger of the Record for the 34th America's Cup.

 

With know-how acquired as members of America's Cup and Volvo Ocean Race design teams, they have developed state-of-the-art design technologies that improve product performance. D3 Applied Technologies include a group of scientists, engineers and external collaborators with proven experience in their field of expertise.

Tested & Approved by Alexandre Cousin, Thomas and Nicolas Goyard

During 12 months, we have run an intensive R&D program with some of the best foil riders in the world.

Nicolas Goyard finished second at the PWA foil in Sylt.

Thomas Goyard won the French foil championship.
