I did this exact thing for my Naval Architecture Thesis in 2009. Made a sail for a Laser. Sailed very differently with regards to a traditional sail, particularly downwind. Very cool how the mast on yours retracts also. Huge amount of labour to build the sail compared to a traditional sail.

Absolutely amazing no more rolling up with cone effect , wet, messy, mildew, is clean, replicates the wing it really is. Someone has finally gone beyond what we’ve been stuck with for centuries. Improved on “ the wheel”...

Simplicity is not the first that comes to mind, when I see this.

Starting Questions: (1) Weight penalty vs conventional high-tenacity dacron sail (2) Material? (3) WHEN there is an air leak, how is this addressed on the water. (4) Do the seams between these tubes provide better laminar airflow? (5) Cost vs conventional high-tenacity dacron sail (6) Flaking and stowing on the boom... looks challenging

I see several things here - would make sense to me to use this with a multihull rather than mono. I have to imagine that it would be heavier than a regular sail, so the wide platform of a multihull would be helpful for stability. Because of that huge inflated sail, if it were to capsize, that would prevent it from going "turtle," instead staying on it's side, which would also be helpful for a multihull that is difficult to right from turtle.

It is rare to see such an original design for sailing. big thumbs up!

I was looking for a way to do this for my solar powered sailboat. This is the solution I was looking for. Thank you.

The “canvas” can do miracles, when I’m sailing! ⛵️

Reminds me of a butterfly wing inflating when they emerge from a cocoon Very cool!

Brilliant! Kit-surf a similar good example also as well some sky-diving wingsuits! 🙌👍

I absolutely love this. Amazing.

Now, combine the IWS with SBS (Sailing Booster System). I saw something similar to this in Woodenboat magazine about a West System wood hulled trimaran that saw speeds of 20+ knots. The sail could rotate 360 around the mast. (He used his sail to maneuver the harbor.) It's interesting to see the wing approach vs the umbrella (catching air) approach.

have to see how it handles reefed in a force 8 before I would ever go with such a radical design

Talk about a beautiful boat to sail.

interesting concept but one that I have a lot of questions about. 1) I see no rigging of any sort, so does that mean that there is a limit to amount of wind that set up can take? Can it take winds up to 20 knots and above? 2) What is the maintenance like if you get a tear in the sail? Does it come apart in sections or do you have to take the entire sail off to fix lets say a simple wear and tear hole? How easy is it to take the sail off? 3) Since there is no rigging for the mast that I can see, does the boat need extra support to be able to take the loads in the mast hole itself? Does the boat need to be re-enforced to be able to take the pressure this setup would put on the boat. 4) What are the overall benefits to this setup? Is it lighter, stronger, more efficient, does it capture more air somehow than a standard sail, what? 5) How much air do you need to fill up the sail? What extra gear does one need to make this set up work? 6) What is the sail material made of? What kind of life expectancy can we see with this material and overall setup? 7) I'm worried about the mast, it looks like it's made of individual collapsible4 components that make it able to rise and lower but my concern is the structural integrity of the mast itself, which goes hand in hand with my first question about limits of wind pressure it can take without rigging. 8) Is it cheaper than a standard rig? (probably not considering the radical design) 9) If one does get a leak and lose all air in the sail, can you still use the material as a conventional sail in the event of absolute air loss as a back up plan? (i'm talking about for those boats that have no radio or engines) 10) How practical is this at the end of the day, as a sailor and one who knows about sailors, we tend to be very practical people (with the exception of actually owning sailboats). Overall does this make any sense, and does it beat conventional setups in strength, utility, weight, maintenance, durability, ect? or is it just a fun idea with a bunch of limits? 11) Are there limit's to the size the sails can be? 12) How much weight can this sail handle, I have a Hudson Force 50 ketch that weighs a shit ton, would this sail design work well with my cruiser type boat? I kind of like this idea and it looks kind of cool, but if that's all it is then I have trouble with seeing the point of this design.

the genius of man. love it

Great idea!

I don't want to comment I just laugh when I saw how is your mast rise up 😂😂😂

I would liked to see more of how it raised and lowered and the basic structure.

Are you kidding me!! That's genius!!!!

amazing! love to sail this

fabulous !

beautiful

Clever and elegant, but a big part of the fun of sailing is adjusting the tension on the sail to make it the ideal shape for the wind direction and strength. One obvious advantage is that if you capsize, the boat will never turn turtle.

Up to 20 knots... I can imagine what stronger wind could do with it

The Birds have you beat on this concept, but I love it that you are attempting to show us all, that someone had understanding for lift a long time ago, millions of years ago.

Finally I was thinking about this a while ago (with a mast)

Well Done!

super Idee auch für die Verwendung von Segeln für die Normale Schifffahrt!

Beautiful, and a great potential for better efficiency - compared with classical sails. This is the very first possibility to use true aerodynamic wing profiles for sailing. Congratulations !

I don't even sail, but I want one

All things have to pass through the three stages of truth 1. It is Ridiculed 2. Violently opposed 3. Finally scene as self evident, I like your idea very much!!

Love it🔥🔥🔥🔥

amazing

I love it.

Seagulls will love it.

Just need the sail to convert the sun into.useable electric at the same time. That would be a big leap.

Very nice! What kind of boat is the hull taken from if I may ask?

Is there anyway to reef or reduce sail area/wing area ...?

진짜 좋은 아이디어네....날개단 요트... Good!!!!

I’d love to strip everything off my 30’ trimaran and just use one of these! Where can I get it? More info please.

Brilliant

Nice shape.

When the boat sinks, one could hop on the sail and float away. Is it a sail? Is it a life raft? It’s neither, or may be it’s both.

So it has fans in the sail leading edge. Battery powered, I assume. So can you call for roadside assistance for a flat battery?

All I see here is added complexity hidden under the guise of an unstayed mast

This guy must have lungs of steel.

Iws...irritable wing syndrome? Got my tongue hard though. Great idea.

Gr8 idea. I would want my perfect yatch . A Big jet Cat with telescopic wing sail and kite sail.coverd in solar panels. Sides, roof etc hydrogen generator.

I like the design principle being simplicity, but i cant help but feel there might be drawbacks when compared to an original style sail? if so could anybody let me know? thanks!

I heard Beneteau was planing to use this in on a catamaran in 2022. Is that true? When is a crusing application expected?

Pretty cool idea. Will stick to regular sails for a few years before this goes mainstream tho... something about this looks not "sailing" enough for me yet. (I Said yet, I understand how things evolve ok? )

Nice yacht.Would love one.Available in NZ?

How did he do the gybe?

Must need a decent pump and battery to inflate, wondering how to put in a single or double reef??

Can it be reefed for high wind safety?

Two small 100w fans maintain the shape of the sail with tiny pressure. The sail positions itself almost by itself, there is no tension to hold it in place. It works very well in heavy weather. It is not a competition sail. The boat is more stable than with a normal sail. It could well be a breakthrough invention. Check it out on their website inflatedwingsails.com/en.

What trickery do you evolve to get this done???🤔

Is it inflated by the apparent wind or pumped up and sealed like a balloon.

Perfect for the Puget Sound.

Needs cambers like on a windsurf sail that creates more shape in the sail to give it even more power

E o preco?

What....No technical data? No manufacturer. I love the jibe. Now I have to play Sherlock Holmes and find out who made this. I'll be back.

that inventor deserves a round....

I just realized. How does this run down wind?? can it open and double the surface? that would be really cool :D

Well shouldn't the canvas be filled with air to create forward push?

I've seen lots of adverts promoting how awesome the wing-sails are, yet I didn't see a proper review yet. In addition to costs, I can guess they have flaws... I'm not sure for example how performant that wing is going downwind...

Interesting concept. I wonder how it stands up to a bit of a blow. How about reefing? Can't see how that is possible.

He needs an inflatable life preserver ILP:)

Is it inflated by the wind or an air compressor?

what is the benefit?

How to trim it?

Now you only have to make it wing shaped.

Try it in a cat or tri and I'll believe. Seems the downwind would flatten which is the point. I'm interested!

Can lightning destroy this sail and could it be replaced easily?

eventually ... someone has done it ! Great ! this is the future

CGI was pretty good.

대박이다...

How do you reef?

They did this with a hang glider, why not, seems efficient

Нифуя се! Впервые такой парус вижу.

Looks a little bulky and ungainly when not inflated. Beautiful in use though, very nice!

I bet a puncture would be a real let down. Probably better in partnership with other propulsion - commercial freighters? Should be easy store, inflate, deflate and store remotely.

This is super smart. Was this designed by Paragliding engineers?

He driving it like Laser.

"Simplicity" ... You mean "Complexity"

does it have to be a black monolith

Cool concept. I race semi-professionally. Will be interesting to see if this takes off.

what!!!!! wow

Very interesting sail features. Also... who made that hull? Very clean.

Why is this better than sails!?

There is no way that much fabric isn't at least triple the weight of a standard sail, and how to reef it in a storm?

What is the design or class of the actual boat? beautiful design

Without a jib, there is no Bernoulli channel. The sail matterial and the fact that it is thick prevent from fine tunning. So this boat will be slow and unefficient. But it looks fun for those who are not sailors...

Freakin` KIWI`S small country ( population ) brilliant inventions/innovation! Well done bud. A " Can do " people. No i`m not a Kiwi. Aussie. Credit to where it belongs, A` cuz!

what song is this

Se infla a pulmón o a pedal?

can anyone identify the model boat this is?

Any one knows the type of boat in this video?

There's an article on them with all you would care to know located here www.yachtingworld.com/extraordinary-boats/inflated-wing-sail-121282
