iFLY – FAQ
The most innovative development in foiling technology
The iFLY is built around one key idea: speed with control. Its FlySafe® dynamic intelligent foil control system supports stable flight, so the sailor can focus on trim, speed, angles, and manoeuvres instead of constantly fighting ride height and pitch.
FlySafe® is iFLY’s dynamic intelligent foil control system. It controls both sides independently and operates fully mechanically, with no batteries, no charging, and no electronic dependence on the water.
The iFLY is designed for very early take-off and starts foiling from around 6 knots of wind. At the same time, it offers a wide usable wind range, depending on sailor weight, setup and skill.
No. The iFLY was developed to give sailors with solid trapeze skills a fast and realistic entry into foiling, while still offering enough performance for experienced racers in stronger breeze, waves and more demanding conditions.
Both. The platform is designed for both singlehanded and two-up sailing, with no real compromise in concept. That makes it a strong option both for personal performance sailing and for coaching, training or shared sessions. Crew 1-2 – max. 180kg
The iFLY15 One Design offers easy access to foiling. The iFLY RAZZOR Pro is the more aggressive performance version. The main differences are the bigger racing rig, special foils and the additional trim possibilities made possible by the sailor-controlled Main Foil Differential Technology, MDT, working together with FlySafe® for even more performance. Only on the iFLY RAZZOR Pro and aimed at advanced sailors, MDT gives the sailor additional control over the main foils while sailing by changing the foil’s angle of attack on the water. In practice, this creates more righting moment, more performance potential, and better support for bigger rigs, especially for sailors pushing hard upwind and in racing mode.

Yes. The iFLY is easy to tow behind a car on a conventional road trailer, whether diagonal or flat, quick to rig and simple to launch from the beach with a conventional trolley. From dry dock to ready to sail in around 10 minutes, it is practical enough for real sailing life.
Yes. The iFLY European Cup Le Mailly on Lake Geneva is the key annual class event and a major meeting point for the iFLY and Formula Foil community, alongside coaching sessions and class gatherings.
That depends on your sailing background, but sailors with catamaran and trapeze experience usually get into foiling fast. The key point is that the iFLY was designed to make controlled foiling accessible without holding back top-end performance.
Yes. The iFLY is shipped worldwide, and the iFLY community is truly international, with iFLY sailors and boats active in more than 26 nations. That gives owners access not only to a boat, but to a growing worldwide network of sailors, events, and shared foiling experience.
Stable flight is key for both: First for highest performance and foiling in a wide wind range, including rough and wavy conditions, but also easy access into foiling…..
iFLY stands for uniqueness in design and function. Its superior Flysafe ® active foil control system autonomously supports the stable horizontal flight position in the longitudinal and lateral direction. The 4 T-Foils do not have to be operated by the sailor during sailing.
Average skilled dinghy or catamaran sailors with some trapeze experience can safely foil with the iFLY15 after only a few hours.
Quick access – the immediate sensation of success – steep learning curve.
In the hand of an experienced sailor, iFLY15 offers a
whole new sailing experience with previously not experienced speeds and agile maneuverability.
The flight control system, combined with numerous fine-tuned innovations, ensures safe foiling even in strong winds and rough seas..
Stable flight attitude allows pushing hard, so in good conditions, iFLY reaches high boat speed beyond 30 knots in a controllable way.
IFLY15 offers freedom to fly alone or in pairs. Due to the exclusive use of high-tech materials, iFLY15 is extremely rigid and weighs less than 90 kilos ready to sail. With its low weight and its state-of-the-art hydrofoils, it is airborne in winds as low as 2Bft. / 6 Knots.
iFLY15 has a length of only 15 feet, is easy to transport, quick to get ready to sail, and can be easily slipped from the beach using a conventional beach trolley.
Its sophisticated design reflects the highest demands on quality and function.
