Phantom IRIS F Windfoil
Phantom International is proud to release its second Windfoil: the IRIS F.
The Iris F Windfoil benefits from the same design features as the IRIS R Windfoil but in a more affordable High-end prepreg carbon lay up: the high tensile T700 (T700 is used by all major brands for their high end windfoils). Its mast and its fuselage are also shorter (95 & 90 cm) to cool down the beast for a better control and confort without sacryfing the adrenaline and performances.
The Iris F has been developed by Alex Udin, designed by Gonzalo Redondo D3 Applied Technologies, structured by Ellis Engineered, and tested by Benjamin Tillier.
HT Strength Prepreg Carbon T700
Other major brands are using the T700 for their high end racing windfoils while our Iris R foils are featuring the high modulus M40J. For the Iris F we wanted to use the best composite materials at the right price without compromising the quality and performances. For these reasons we selected the High Tensile Strength Prepreg Carbon T700.
< 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.
A unique bend and tortional stiffness
The use of the High Tensile Strength T700 Prepreg Carbon allows a stiff mast for greater accelerations, amazing control and stability.
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 best free ride/ free race windfoils 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 Iris F 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.
Structural Layup by Ellis Engineered
Ellis Engineered was established in 2012 by Brett Ellis, an expert in the engineering of composite structures for the Marine, Automotive and Civil/Architectural markets.
Brett has been a key team member in four America’s Cup campaigns. The first two campaigns with the powerful Swiss Team Alinghi, then Luna Rossa Challenge and finally Artemis Racing for the 35th America’s Cup in Bermuda.
Ellis Engineered was created to offer professional services in 3D modeling, structural analysis and optimization, ensuring our clients see the full potential and benefits of these advanced lightweight composite structures.
Ellis Engineered has a proven track record of providing professional design and engineering services for racing boats, production boats, race cars and architectural structures.
Tested & Approved by Benjamin Tillier
Benjamin has a RS:X Olympic windsurfing background and was one the windfoiling pioneers. His expertise and passion has overwhelmed us since the day we met him.
Benjamin Tillier is based in Noumea, New Caledonia and is a reference everywhere in the world for his unique style. We are very proud of what we have achieved with him and look forward to seeing Benjamin leading the PWA windfoiling ranking.

A high-end direct service
We believe the value should be in the product itself, not spread out through a distribution network with several middlemen. That is the reason why our products are exclusively sold on our E-store, enabling us to make better products to a very competitive retail price.
Having a direct relationship between the end user and our brand allows to provide a more efficient and high quality service.
