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.
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…
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?
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
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.
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?
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.
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'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!
@@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).
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.....
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.
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.
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 🪁 ⛵️
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.
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 !!!👊😎
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.
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.

It is just so cool to see 3 men moving at that speed under wind power only on the water. Simply astounding.

Many years ago there was a catamaran called Jacobs Ladder that used kite technology in its infancy.
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.
In other video they reached 37 knots with 13-16 knot winds using a 40 sqm LEI kite (leadin edge inflatable). Very impressive
Amazing boat great video pity wrecked by sound.
WoW, Super special video, thanks for this.... amazing... love from Londom UK
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.
what would u suggest thanks aloha don
What speed did you achieve with this trip? and what was the wind conditions like?
Tacking upwind ? Is that possible?
@@mikaelwester
I think so. Don’t know how high they point, though.
Stunning achievement !
Феерично !!! Enchanting !!!
Great boat what’s the music goes well
Kite-Segel und foiling - das geilste, was es gibt !!!

The turntable is brilliant!
Just WOW.....I'd love to read up on the technology behind it. Anybody got a link to some good reference material ?
looking better everytime. i'm still waiting for a video to see the performance in moderately choppy water.
Or upwind... 🤣
freakin sweet boat and video
Unbelievable! Great tech. Thanks for sharing.
You had me at 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 wish they showed the kite being launched and retrieved.
Interesting.... how long before Larry Ellison copies the design and makes a two hundred footer?
Well put together ! Wish it had more action, waves, turns...
HOWCOOLISTHAT!?!? Great video!
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 .......

Yeah I would of used a 15/17/19 foil for the job
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"
Take a look at czcams.com/video/j3pt03VFK2c/video.html

@@Chris-bm5qd References state that 20 degrees upwind is possible, so why no tracking?
beautiful images
Wow! What are those things called on the front? That keep the water piercing bows out of the water? Some type of forward elevator/canard.
speed ? any numbers ?
Hydrodynamic keel, so cool!

Assolutamente geniale il sistema di stabilizzazione coi tastatori in acqua.
очень красиво!
FANTASTIC !!!
The future of transportation
I would love to see more information on how the kite is first launched and landed etc.
Realmente impresionante !!!! eso es un hibrido entre un kite y un catamaran? Excelente!!!!!!
Where is this project going now? Please update..
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.
How many knots were they traveling?
Now that! is how to travel on water.. beautiful
awesome.pretty hands on.and not for the novice..thats impressive
Фантастика!
Simple question.. how much?!
Comparé à un voilier ordinaire ; c'est tu plus avantageux???

Any estimate as to the cost of these systems?
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 :)
Where is this harbour?
Anybody know what the moving "bouncers" hanging down from each bow purpose?
Line length (range)? Kite size?
I have thought about this alot nice to see people doing it. However the hull shape is wrong for this concept.
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.
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.
What is the function of the "rudder" on each bow? Is it a foil?
das ist der Impulsgeber für die Foils
Magnificent!
Great speed

It is Minor Cause by Emancipator...
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.
how high does it point?
o0bananaman0o I suspect the answer is “this is maxed out right here”.

Can this thing handle the large swell of the open ocean
Pardon the typo. Kiteboat is correct, not kiteboard.
👍 Dommage que vous n'ayez pas indiqué la vitesse moyenne ainsi que les pointes ...😢
what is the fastest speed achieved? normal cruising speed??
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.
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?

Is there any gain in placing the sail away from the craft
