That idea I’ve always thought would work great as part of a rafts survival kit. A smaller version would fit nicely in the seat pan of an ejection seat as part of the raft. Giving carrier pilots greater options to move the raft towards a shore instead of bobbing in the water for days on end.
actually not a bad idea, but to be able to go in a specific direction you need some way to steer raft. but then you are working a kite and a rudder at the same time.
Not necessary as long as your raft is small enough you can tip it with your body weight to make an edge dip in like a kiteboard. It would be tough but doable
Ideally yes. Practically there still a long way to make a small flexible raft seaworthy, truly maneuverable and srong enough to withstand the constant pounding of the waves … the more so the speed is highr. For the time being I'm not sure it is feasible. The again it may well be that some are working at it somewhere in a gorvernent agency…
Peter Ebel - thanks Peter. I’ve watched foiling moths for ages and never noticed it although it’s very obvious to me now. I think it’s because on this design the sensor wand is stuck so far out in front of the bows it’s very obvious. Whereas the moth has it just short of the bow on the starboard side.
Could set the trim a little higher on the front trim lines. Not overall, but when the kite gets ahead of you more. Maybe an on the fly trim???? But over all a great set up. I've never seen this before. I'm amazed by that. it's a great concept that has great potential. Keep up the great work guys. Love this.
@@whynottable Thanks for the link. I enjoyed that video as well. FYI - "Ready about" is a call-out used prior to tacking, (which this vessel is incapable of) not jibing (as shown in your linked video).
Wow. Thats the coolest thing ive seen in ages. I actually conceived this same idea myself years ago. Its amazing to see it brought to reality by these men. Awesome. Could this be a future AC development?
I've seen this a few times, and I'd love to know why the made the decision to use an LEI over a foil kite. Surely that thing is rarely, if ever hitting the water and needing to be relaunched, so why not save some weight, and gain some performance with a foil kite? Hell, they could probably even repurpose an old 30 metre paraglider!
Was ist das nur? Kann nicht aufhören das Video zu gucken. Und nochmal und nochmal.... Whooooot? Can't stop watching this video. And again and again.....
I found this video 4 years ago (according to my previous comment) and here we are, a total of 7 years later, and I still love it. But where has the concept gone? It seems that a bit bigger but lighter boat $$$$$😖 with computer control of ride height $$$$$$😖 and foil design that prevents a much bigger kite $$$$$😖from yanking it out of the water, would make possible absolutely stoopid speed! C’MON FAT WALLETS, BUILD IT !!!👊😎
Looks like a real nice ride, wonder what it would do with high winds. Would appreciate some stats like top speed and average speed of both wind and boat, type of kite and lines that were used.
Impresionante desempeño, Realmente impensable que se podía llegar a este nivel de desempeño hace 25 años atrás. Por favor más vídeos y detalles de técnicos del proyecto
Interesting boat design, impressive performance, beautiful photography and inexplicably irritating use of 'music' to destroy what would be a very cool video. At least we have the mute button.
Correct me if I’m wrong. One person steers the boat (sorry for not using proper nautical terminology). One steers the kite (the same with kiting terminology). And one controls the pivot for the kite pilot. I’m a former freestyle kite pilot and maneuvering a freestyle kite combines the flying of the kite from the handles and keeping the kite within the boundaries of useable wind by pivoting your body within those boundaries to actually fly the kite. Fly too far out of those boundaries and your kite falls to the ground (or water). I see the person controlling the pivot keeping it in the useable wind window and the pilot maneuvering the kite to find the power zone (I actually had a 4 line traction kite too and know power zone). Right or wrong - still a badass kite boat 🪁 ⛵️
thaaats just great! only concern i have is: how hard is it to restart the kite after it falls into the water?! and how would they deal with entangles wires after that?!
I have a conceptual sketch I made of this marrying of hydrofoil with traction kite from around 2002. It stemmed from a hobie cat that was modded with a seated turntable type control centre like this. I figure the opposite foil to the traction force will trim for down force to prevent it from lifting out of the water. Is this right?
The innovation here is the device that keeps each pontoon from nose diving into the surf by constantly exerting downward force on the tip of each pontoon. That seems to provide the biggest stability benefit (I'm just a land locked engineer that loves sailing, so what do I know).
Jason Robinson Those things on the front are the magic wands that control the trim of the foils to keep the boat at a constant height out of the water. Them moving up and down is from bouncing off the water.
Soon they will be no more sails, Instead, kite sailing will be more efficient faster, and less heeling. The German Skysail already have it fully automatic controlled by a computer on cargo ships since 2009. It's so expensive though.
It can't. Kites are basically reachers; maybe a close reach with a skilled crew and a really flat-cut kite. But it can't go upwind in any meaningful way.
sure, why not? If even I (your average kitesurfer) can go upwind on a primitive 5-foot plank with tiny little fins, a hydrofoiler will have no trouble at all hauling close to the wind, tacking, and running circles around a conventional foiler with the same sail area.
Wind is always a bit slower at the surface due to friction and turbulence thrown up by the uneven “terrain”. The higher you can get the driving sail, the better.
@@psgouros I know that I used to sale myself many years ago but surely you must pay a price for having long lines out and a lot less control when changing direction. A spinnaker sail adds lots of sale area without intruding on other vessels the way long lines would.
a) stronger winds aloft , b) next to no heeling moment, and most importantly c) the ability to increase airspeed at the kite to double or triple the boat's apparent windspeed by steering figure-8s. This yields far more power per wing area, and allows an experienced pilot to keep airspeed near the optimum for which the airfoil is designed across a range of wind conditions and courses. It's only a matter of time before the AC discovers this too.
I have a design in my head for similar devices. Basically a submerged shuttle/ anchor with depth control to keep tension and height controlled. My idea is that the shuttle keeps the kite pulling forward instead of up or sideways. Same design could just be a submerged shuttle kite and harness and you could ride the kite from 20 - 40 feet up in the air.
@@jonathantrekallover9369 I read a brief description in a kite book definitely over 20 years ago of it having been done. I looked and have been hoping for more information ever since.
Piloting one of these (or is it just "this") craft has have the coolest vibe, since you're doing something no one else in the world is doing.

@@ggerharten Kite buggy el timón se maneja con los pies
It is just so cool to see 3 men moving at that speed under wind power only on the water. Simply astounding.
I love this concept, and specially how they’ve managed to automate the pitch control on the foils. 👍
The Moths are exercising this since many years.
Peter Ebel - thanks Peter. I’ve watched foiling moths for ages and never noticed it although it’s very obvious to me now.

Wonderful design. It looks like all three of you are intent on breaking some records. Gives a new meaning to skysails.
Absolutely amazing - well done! Now, you may see why the AI programs and technology NEVER replace the human brain in terms of new concepts and ideas.
Amazing boat great video pity wrecked by sound.

Many years ago there was a catamaran called Jacobs Ladder that used kite technology in its infancy.
Kite-Segel und foiling - das geilste, was es gibt !!!
Would have been nice to see it tack, jibe and run downwind
Think kite surfing..This is not sailing with a jib
Two words you will never hear said together on that boat: "Ready about"

Yeah I would of used a 15/17/19 foil for the job
Are those little mantis feelers trimming the foils on each outrigger? That's genius.
Yes took me a minute to realise, a lot of hydrofoil sailboats have those as wel
It’s interesting that when I was wondering how to apply foils to a power boat, this was my thinking 💭 that ship has long sailed so to speak! 😆
The implication into active stabilization for all mono hulls is huge no power consuption required just wear of moving parts.
looking better everytime. i'm still waiting for a video to see the performance in moderately choppy water.
Or upwind... 🤣
Mega cool video but why would you not give us the speed that's what everyone would love to see
jim wortham that would have made too much sense
That is speed, what were you expecting?

In other video they reached 37 knots with 13-16 knot winds using a 40 sqm LEI kite (leadin edge inflatable). Very impressive

Realmente impresionante !!!! eso es un hibrido entre un kite y un catamaran? Excelente!!!!!!
awesome.pretty hands on.and not for the novice..thats impressive
Well put together ! Wish it had more action, waves, turns...
This has to be the most unusual sail/kite boat ever made. 36.3 kts max speed is fantastic.
Except for the Sailrocket, which currently holds the speed sailing record of 65.4 kts .......
Unbelievable! Great tech. Thanks for sharing.
thaaats just great!
only concern i have is: how hard is it to restart the kite after it falls into the water?! and how would they deal with entangles wires after that?!
I wish they showed the kite being launched and retrieved.
Now that! is how to travel on water.. beautiful

Where is this harbour?
I'm curious how close to the true wind direction it can beat.
It can't. Kites are basically reachers; maybe a close reach with a skilled crew and a really flat-cut kite. But it can't go upwind in any meaningful way.
Great emergency option.
This can save lives. Well done 👍
I have thought about this alot nice to see people doing it. However the hull shape is wrong for this concept.
freakin sweet boat and video
Each lifeboat of every great vessel should have one of these kites in order to allow them to move to the shore
Looking for crew????.........Please.
очень красиво!
Simple question.. how much?!
Whats that thing at the left side of screen in 5:00 ? is it a submarine coming up to surface ?
looks like a kayak or canoe
those are outrigger canoes
Hahah so i have a vivid imagination :)) thanks for the answer, and i loved that kiteboat.
how they can return
Can you upwind any angle?
sure, why not? If even I (your average kitesurfer) can go upwind on a primitive 5-foot plank with tiny little fins, a hydrofoiler will have no trouble at all hauling close to the wind, tacking, and running circles around a conventional foiler with the same sail area.
Magnificent!
What happens when you in the middle of the Pacific & the wind drops?
Same as on any other sailboat: you bring out the beers & wait for the wind to come back :)
I had a dream about something like this, over 10 years ago before anyone even thought of it.
me too
apparently it takes a lot of energy to make something go 36kts this gives me some good ideas.
you and a thousand other people. "Waterworld" is much older than 10 years...
Is there any gain in placing the sail away from the craft
Wind is always a bit slower at the surface due to friction and turbulence thrown up by the uneven “terrain”. The higher you can get the driving sail, the better.

beautiful images
Line length (range)? Kite size?
Nice ... but to jibe it takes half ocean!!!!
А если это ещё передать в управление на машинное обучение и потом поставить робота на полученных данных
Nice images lacking bot weight, kite size, windspeed, main speed averages @wind angles
So fun fact another company I think is going to put a kite on a container vessel! How funny that we see one in this video
What about forwarding motion of the vessel with head wind?
same as any other wind driven water device like sailing boat, windsurfer, kitesurfer ...
Well that’s awesome, the tac just throws me off, thinking about it.
Great speed
how many m2??
This concept seems a little high strung imo.😁😂
booooo! :P
