iFly15 Foiling catamaran
iFLY – FAQ
The most innovative development in foiling technology
“We love SPEED while keeping CONTROL.” That is the core idea behind the iFLY® foiling catamaran. Its FlySafe® foil control system delivers exceptional flight stability and control at speed, allowing the sailor to focus on trim, speed, angles, tactics, and maneuvers instead of constantly fighting ride height and pitch.
FlySafe® is iFLY®’s dynamic flight control system, controlling the ride height of each hull independently and working fully mechanically, with no batteries, no charging, and no electronic dependency on the water. It gives iFLY® a level of flight stability, control at speed, and composure in more developed sea states that no other foiling boat under 20 ft delivers.
Often from the very first session. Many sailors experience their first real foiling within the first few minutes. Of course, this depends on your sailing background, but sailors with dinghy or catamaran experience, and ideally some trapeze experience, usually adapt very fast. The key point is that the iFLY15 was designed to make controlled foiling accessible without compromising top-end performance.
No. The accessibility-focused version of the iFLY15 was designed so that sailors with basic sailing skills and some trapeze experience can already have their first safe foiling experiences. At the same time, it still offers plenty of performance for experienced racers in stronger breezes, waves, and more demanding conditions.
The iFLY15 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 the sailor’s weight, setup, and skill.
The iFLY15 One Design is the more accessible version: The easy entry into foiling. The iFLY® RAZZOR Pro is the sharper, more advanced performance version. Its bigger racing rig, dedicated foils, and sailor-controlled Main Foil Differential Technology, MDT, unlock a higher level of trim control and performance. Working together with FlySafe®, MDT gives advanced sailors more control over the main foils underway, delivering more righting moment and more performance potential, especially upwind and in racing mode.

Both. The platform was designed from the outset for both single-handed and 2-up sailing, with no compromise in concept. It supports solo sailing as well as double trapeze sailing, making it a strong platform for performance sailing, coaching, training, and shared sessions. Which setup is faster depends on the conditions. In stronger winds, 2-up is often quickest. In lighter winds, single-handed sailing can have the edge. Crew 1-2 – max. 180kg
Yes. The iFLY15 is easy to tow behind a car on a conventional road trailer, either flat or diagonally, quick to rig, and simple to launch from the beach with a conventional beach trolley. From ashore, the iFLY15 can be ready to sail in around 10 minutes, making it highly practical for real sailing life.
Yes. There is a visible and growing class scene, with appearances at events such as Foiling Week, Ronde om Texel, and Duc d’Albe, and with the iFLY European Cup Le Mailly on Lake Geneva standing out as the annual highlight, where sailors compete for the historic Silver Cup.
Yes. The iFLY15 is shipped worldwide, and the iFLY® community is truly international, with 250+ iFLYs sailing in 27 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.

IFLY RAZZOR PRO – THE NEW IFLY FOR EXPERIENCED SAILORS
THE iFLY racing VERSION ENABLES EVEN HIGHER PERFORMANCE, to sail in extremely tough conditions and allows sailing with XXL rigs.
