- What happens if You develop a revolutionary wing rig and put it on the iFLY15 ? It is incredible, must see and experience !
Exhilarating high speed sailing, foiling above the water surface. The Foils are controlled by FlySafe ® Automatic foil control system. The system is a CEC Catamarans GmbH enhanced
mechanism to stabalize the boat while foiling.

I would like to see side by side testing of the different sail rigs offered by iFLY15. When the windsurf sailmakers introduced camber-induced sails I thought that was one of the best sailing innovations, stable and able to sail in gusty conditions better.
so true. Besides higher speeds, especially in strong wind conditions, the main advantage of the wing rig is a much more stable flight attitude. The lateral flow is less disturbed than on a traditional single layer sail. This means that the iFLY Heru softwing rig is much better to use in gusty conditions or strong wind.
That wing is so well thought out and structurally synthesized. The drive of any sailboat depends on the angle between the vector of the apparent wind and that of the direction of the boat. That beautifully " almost solid" curved, upper, leading-edge on this rig, ensures maximizing the forward-tilted, total lift vector, on that wing, to provide a higher propulsion component acting in the direction of the hull. No soft sail can really do that with the pressure zones existing close to the leading edge. Hearty congratulations, it makes a very old sailor like me want to be younger, to go and try it all out in a strong breeze. Again, well done, with such good use of modern materials to play about such that apparent wind blows always on my nose, rather than on my cheek, irrespective of the direcctions of the boat which separates it from the apparent wind.
it is wonderful to get such positive feed-back from people who have a deep understanding of aerodynamics and propulsion. Thank you, you made my day :-)
Awesome!
Good jobs guys !!
the team is very motivated by Your positive feed-back. Thank You :-)
This keeps the motivation and our passion always up
I want one now!
Hi. I am available for all Your questions via email EMichael@iFLYsail.com or via Facebook facebook.com/emichael.miller and facebook.com/cecsailing/
Foiling is Fun.
>>> HAVE A GOOD FLIGHT > HAVE A HAPPY DAY
if you guys had more like 50 or 100 high quality videos people will go to your site and hit the 'buy' button. they won't be able to resist
So its like the RAF (rotating assymetrical foil) on windsurfers in late 80s. After tacking you had to shake the sail to snap the roraring bit around
no shaking needed. It flips even easier than battens in conventional mainsail a-cat style. Effortless.
This looks like a windsurf racing sail. With full battens and cambers and a very deep mast sleeve. Windsurfers use these kind of sails already in the 90-ties.
it is true that the technology has something in common with high speed windsurfers. The developer, Giulio Iviani from Heru Sails, is one of the leading heads in this technology. (Marco Aggravi, ITA108 sailing with Giulios rig). However the softwing rig for catamarans is a lot different and further developed. It can handle the challenge of spreaders, works with a wing profile mast, can be pushed up like a state of the art a-class decksweeper sail and enrolled when lowering sail. Stowing volume comparable to classic mainsail. Twist as well as profile depth can be adjusted. 3D volume between layers is watertight. Wing is floating t.b.c.
A rotating (wing) mast is key to efficiency.
Remember that windsurfers *always* had a rotating mast due to the inherent mastsleeve. Later the rotating battens appeared: the full battens did not stop aft the mast but next to it, providing perfect leeward (wing-like) profile (see fingalslastpint's comment); but rotation when tacking or jibing was hard, youhad to "help" the sail rotating.
And then appeared the camber inducers, providing much better rotating, probably just like your wing sail; unfortunately, camber sails are not for amateur surfers (mast sleeve is hollow which can contain lots of water, so water start is almost impossible).
@@markbaa I was never an expert windsurfer but used cam sails for my bigger sizes with no problems waterstarting. They were a bit heaver though. And that didn't help things much.
i think what u have created here is something perfect! I have been looking at all this foiling technology over the years (first got interested as a kid when I visited Alexander Graham Bell's museum in Nova Scotia) and have been waiting for this - something that can be sailed single hand, a cat, and is totally stable and not big workout, simple and easy to transport, setup and launch. I sailed a 18 ft HobieCat single handed for 8 years on Lake Ontario Canada and always dreaming of one day having foils under such a beast. I think this is it? Have you considered a jib? Where can I purchase?
Hi angusmacsac, thank You for that wonderful feed-back. My motivation for building the iFLY15 is exactly the same. This boat was designed and built to be my personal perfect foiling beauty. And I know that many passionate sailors are thinking as You and me. So I am building the iFLY15 in large serial production to have high industrialized quality and affordable pricing for such a high tech product. You can contact me via EMichael@iFLYsail.com or via Facebook facebook.com/emichael.miller and facebook.com/cecsailing/
we have a nice research project about a innovatiave genoa called CodeF (Code0 for fly). It is very promising for very light winds and is sailed on all caps, also upwind...
By the time I convert Euro to CDN $, pay your VAT i get about $39,000 CDN for the "Ultimate" pkg. There would be additional cost of shipping it here to Canada :( Looks like I will have to wait until prices drop before I can own one. Unless you're looking for someone to sell them in Canada! - LOL
Hi, don't worry. Looks like we will be able to get one container full in summer, going to North America. Contact me and we might find a way. EMichael@iFLYsail.com. We can make an appointment to skype.
Great but not yet perfect! Sorry .There's no way to have a smooth tack . Each time great braking and splashing in the water. The boat almost stops. There's no room under the sail to change side quickly while foiling.
WOW The future is here
I like it ⛵️🛶❤.
This thing here is the only acceptable future of sailing, aside from kiting! Great stuff how much does it cost compared to a regular high end composite sail over lifetime?
I would not say it is the only acceptable future, but to combine the advantages of a wingsail à la Americas Cup with the availability and suitability for everyday applications, this is quite attractive. You can roll it up like a conventional sail, easy to hoist and store. And another big point: it is floating, as the volume between the two layers is watertight. So no turtle. Easy righting!
wanna build my own.. exciting stuff
this is what I did :-) But to achieve a result like this, it turns out to change Your life. And You need a great team of the best experts ...
Nice sail. Where can I get one?

I'm assuming it is the same sail area as the standard one.
What is the increase in efficiency?
How much more lift speed, percentage wise? Do you know?
I fabricated a rotating mast on my Coronado 15, and I think I increased its speed by 20%.
with same sail are we observe lower drag and higher end speed, especially in strong wind conditions. Other major advantages of the Heru wing rig : as the laminar flow of the air is less disturbed, the wing adds stability to the flight attitude. There are less turbulences. The wingsail is less beating in gusts. Last not least, I like the fact that the wing is floating. Pmtge pockets between the two layers of the rig are water tight. It is even easier to righten the boat after a capsize.

@@iFLYsail
I like it! But what percent would you guesstimate in efficiency?
I used to race 18square's, technical improvements were welcomed. I prefer singlehanding.
We had, what we called solid wings (not really solid) which generated more power. Took five guy's to help set up. Good in light to moderate air. Disadvantage in a blow and rough seas. Your wing looks to be the best of both worlds.
My guesstimate would be at least 10 - 15%.
It would be interesting to pit two in a race around a triangle course. And compare the times.
I love this stuff!
If your main is stalling or callapsing before your jib, then something is wrong.
Can you adjust your mast diamonds stays and flatten your main, or outhaul? Or is it too stiff and your stuck with it. We are getting technical now, this is where I love to go. My boat was not a foiler, so I'm trying to convert. I devised a quick instant method to adjust the diamonds, which proved to be deadly in racing. Flatter when beating, fuller off the wind and when rough. I think with foiling, flatter all around with increased apparent wind speed.
Thanks for your response!
I might estimate it a 5% gain in efficiency (in stronger wind), which is huge.
yes, e can flatten the sail by shifting the diamonds, the dowager rake, eveb the spreader length. This gives us plenty of options to trim the mast.

What is the difference with a Windsurf sail?
a lot of difference to a windsurf sail.
mast having spreaders
You like to push up sail like on every catamaran, not capsize the boat or flip the mast
the volume between the skins is watertight, the wing is floating
the softwing is designed to be hoisted on conventional wing shaped mast with track
the spacers are flipping when tacking, creating an asymmetric profile
it is patented technology by Heru sails
the spacers are jumping, creating an asymmetric profile. The catamaran softwing is hoisted the same way as a normal catamaran mainsail, solving issue with spreaders.
its more complicated for the same result....LOL. Heru have been persueing wing sails for windsurfers for some time without success because they are too complicated. It does however seem to fit the catamaran better than a Formula windsurfer or foil. Definitely a good wing for boats based on windsurfing cambers etc.
Pity you didn't sail a standard sail alongside the "wing" sail to see the difference (if any).
Wery interesting, but is this actually a wing?
it is a three dimensional wing, avoiding the disadvantages of a rigid wing. Can be hoisted as a normal sail. No need for a crane. Not so fragile.
Alas... 25K € the ship and more for the wing mast makes it unaffordable for my sail club...
i'd really love to fly with her, just to brag on the phantom who sail near our hobie 16 when it come windy in Cannes :)
any way i'll be curious to see how she does when its quite wavy (0.6/1m height, 3 to 4 meters between each wave, like we have in mediteranean sea...
You will love to see how stable she flies in the waves of the mediteranean sea. iFLY has been tested a lot under those conditions, in winterly mediteranean sea at Barcelona and Estartit, as well as in Britanny. Have a look at the older TH-cam videos.
In technical terms this is a "high aspect " ratio rig.
As in " if I stick a huge eff-off sail on her, high aspect she'll go faster ".
Whaaaa... shut up and take my money!!!!
Shut up!!! That's so fucking awesome iit's not real hahaha!!!
I'm not getting younger and I'm a bit out off shape, but I get serious itches to get back into shape just for trying this once.
I've been sailing small boats as a kid and I had a windsurfing board until it got stolen.
I'm seriously contemplating take a stab at this after being bombarded by youtube with videos of iFly foiling!!!
Awesome machine but way too expensive. Keep the price that high you’ll have minimal buyers, lower the price and you’ll make money exponentially. Economics 101. Plain and simple FACT.
thank You for Your advise. Please contact me to join our team. Maybe You can help to reduce cost at production, but without lowering quality. EMichael@iFLYsail.com
Love this reply, easier said than done. However I do know how to make your boat cheaper, but it will come at a cost of quality over time. Most people call it China ;-)
