Beautiful video that remind me my first impression when I was in France in Arcachon bay. I was amazed by kite surfers traveling along the coast next to Lacanu ocean. I observed them when I was hiking along the coast looking for Atlantic birds. As birdwatcher I see often kite surfers but I never immagine to find so many of them traveling and not just stick to one locations. I was very impressed by this french aproach and now with this video I see they evolved concept magnificly
This cat seems to have a very wide beam. Most cats that I've seen have about a 2:1 length to beam ratio, but this one seems nearly 1:1. Like the two bows and two sterns make an almost perfect square.
We just had a big ship from E.S.A come into Cap Canaveral . The ship is equiped with four reefable "Thick" sails. Europe is so far he-head in this technologie.
Thanks ! We still need 2 crew members to launch and recover the kite (to inflate it, connect lines, and unwind it to the flight altitude with a remote controller), but once the kite is in flight mode, everything is automated, and the automatic pilot steers the kite either in static or dynamic, depending on the heading of the cat.
The kite is actually the good size for this cat, but we are also sailing with a 100 m² on it. We don't want it to be a race catamaran but a demontrator of our automated kite traction system SeaKite, to be equipped on any other power boat that could use it to reduce their fuel consumption and thus emission of greenhouse gas.
These hulls look quite familiar. I always wondered what became of the "Mediatis Region Acquitaine" concept. Seems like a much better use than on a catamaran. Good luck with this. The Boat looks great. Now put some speed into it - but with care.
For now the goal of thi cat isn't to race, but to demonstrate our automated kite traction system SeaKite to be installed on power boat to reduce their fuel consumption.
Le système SeaKite ici est directement fait pour soulager la charge moteur du navire équipé et donc réduire sa consommation de carburant. Nous avons aussi un autre système de sécurité, appelé LibertyKite, qui équipe déjà beaucoup d'Imoca et d'Ultim pour leur sécurité.
It's going upwind quite well ! With this cat we sail at 50° of True Wind Angle. The ability to go upwind doesn't depend on the kite itself, but more on the hull efficiency.
Yes the flight in fully automated. On this catamaran, the kite is the only propulsive system, so fuel savings of 100 % ! For other vessels, we advice the kite surface based on a 30 % average fuel savings per year.
@@beyondthesea-yp so from release it's all automated? So if I've got a vessel I just install the system and when it thinks it could work it releases the kite until it draws t back in when wind/situation is not suitable?
Yes it can go downind, this is where the kite if the most efficient. Only issue with this cat is that it goes too fast and then it breaks this apparent wind. Regarding safety, there is a Matrix Of Permitted Operations included in the automatic pilot in which one factor is the free space around the vessel, and if there is not enough the kite is flying back to zenith mode above the equipped vessel.
There was a prototype power plant a few years ago that used a kite flying more or less figure eights as its power source. Is this a continuation of that reach or a new program?
This is a new program, power plant with kites are still running, but we are developing kite traction systems to tow vessel, with the final goal of towing commercial ships (with kites up to 800 m²).
Great looking system. Could it be installed in any ship, or must it be built to spec for the system? There are several programs using more traditional sails on cargo ships. Is this more efficient? I have flown kites most of my life, your program really appeals to me in an aesthetic way as well as the engineering. Best of luck to you.
Basically, we advice the surface of the kite based on fuel savings of 20 % per year, but it can be way more as it can be less, depending on shipowners wishes. A kite can develop a traction up to 100 kg/m², a classic sail is around 10 kg/m².
Hi, with this cat we can go up to 50 degrees of True Wind Angle. The kite is indeed very efficient to go upwind, the difficulty is more into the hydrodynamic of the boat itsef and is efficiency to counter the drifting force.
Impressionnant ! ...la gestion de l'engin doit être assez cocasse avec un peu de mer et une ou deux belles rafales en adonnantes ou en refusantes Et pour remonter ça parait compliqué on ne peut faire que du portant apparemment non ? Je vais garder mon mat encore quelques temps je crois...
@@jipegame que du portant, ça m’étonnerait sérieusement. En tant que kitesurfer, et avec un flotteur adapté mais pas optimal (coule si vitesse trop faible), je remonte déjà facilement au vent.
@@sebcam9498 Mouais ...c'est incomparable avec un voilier monocoque classique en terme de cap de toute façon Mais ce qui est faisable sur une petite planche de kite ne l'est pas forcement avec un gros catamaran
Merci de votre commentaire. La gestion du kite est totalement automatique, grâce notamment à ce qu'on appelle la KiteBox sur le pont du cata, qui pilote le kite en statique ou en dynamique selon notre allure. Le point de tir du kite étant au niveau du centre de dérive du cata, il tient bien son cap pendant les rafales et les prises de puissance de l'aile dans la fenêtre. Pour ce qui est des allures possibles, nous remontons avec ce cata à 50 degrés du vent réel (il ne faut pas oublier que le kitefoil remonte aujourd'hui mieux au vent que presque tous les autres supports). La capacité de remontée ne dépend donc pas vraiment du kite, qui a une finesse assez élevée pour être efficace à ces allures, mais plutôt du plan anti dérive du navire équipé du système SeaKite.
We've already used the system in open sea conditions several times (for now 4 meters waves and up to 40 knots of True Wind Speed) with the 60 feet catamaran, and this is where we had our speed record with the 50 m² kite (20.5 knots) !
The kite used in the video is a 50 m², which is already enough to tow the cat at 20 knots ! The 100 m² is currently on trials onboard, performances are impressive and we can't wait to show more about it !
Why in the world would you choose a cat over a tri for a kite boat? As long as you can make small adjustments to the point where the kite is attached, or just keep it low enough, you'll be able to reduce your hull drag by flying both amas. 🤔
You're totally right ! But the point of this cat isn't to be the most efficient or the fastest, but just to demonstrate that automated kite traction exists and is ready to be intalled on vessel.
Ou l’agressivité de celui qui ne sait rien mais qui la ramène quand même, 1- la société est basée sur le bassin, 2- Parlier connait « un peu » son sujet, 3- où est le problème d’un navire navigable et maniable qui navigue avec une aile qui est en l’air 4- et vous avez raison vu l’exiguïté de la zone, la navigation sur le bassin devrait être interdite aux bas du front. Respirez à fond, ça devrait bien se passer 😂😎🌴
Looks fun. But it’s a toy without sails. Low wind day with this design would be a beach day. You’d be stranded. I’d love to see it added to a boat with sails as a turbo option. lol. ⛵️🪁
The system SeaKite is to be intalled on any types of vessel to decrease their greenhouse gas emissions when it's windy (above 10 knots of apparent wind). When the kite can't be used, it is stored on the deck and the equipped vessel can run on its engine.

Indeed, it is approximately 18 m long and 16 m wide, because it has been initially designed to have two masts (have a look at "Hydraplaneur").
Small catamarans aren't as wide because of road legal trailer width. Once you get too big for towing, most large cats are pretty square-ish
We just had a big ship from E.S.A come into Cap Canaveral . The ship is equiped with four reefable "Thick" sails. Europe is so far he-head in this technologie.
Many awesome projects are coming up these days, becoming more and more concrete !
This thing is so cool! Now, does it require two separate people to steer and trim the kite?
Thanks ! We still need 2 crew members to launch and recover the kite (to inflate it, connect lines, and unwind it to the flight altitude with a remote controller), but once the kite is in flight mode, everything is automated, and the automatic pilot steers the kite either in static or dynamic, depending on the heading of the cat.
@@beyondthesea-yp that is absolutely spectacular. Genius!
Thats a pretty small kite and they really never kept it down low for maximum power... looks like the boat could have foils too

Super de voir ce catamaran à redans si particulier naviguer... Super projet...
Yves Parlier a reussi a recicler son ancien cata. Super!
Effectivement, l'hydraplaneur est maintenant le démonstrateur de la traction automatisé par kite !
This could get complicated in a race.. Can you imagine the start line and if 2 kites tangled?
For now the goal of thi cat isn't to race, but to demonstrate our automated kite traction system SeaKite to be installed on power boat to reduce their fuel consumption.
L'idée est très bonne surtout en cas d'avarie de mat sur un imoca, océan fifty ou maxi

Does this have the ability to sail upwind or is it only a downwind craft?
It's going upwind quite well ! With this cat we sail at 50° of True Wind Angle. The ability to go upwind doesn't depend on the kite itself, but more on the hull efficiency.
Is the kite system automated? And what is the current and expected reduction in fuel consumption?
Yes the flight in fully automated. On this catamaran, the kite is the only propulsive system, so fuel savings of 100 % !
For other vessels, we advice the kite surface based on a 30 % average fuel savings per year.

Can it go downwind (can the kite drift down)? What about safety onboard, how do you protect ppl from kite lines?
Yes it can go downind, this is where the kite if the most efficient. Only issue with this cat is that it goes too fast and then it breaks this apparent wind. Regarding safety, there is a Matrix Of Permitted Operations included in the automatic pilot in which one factor is the free space around the vessel, and if there is not enough the kite is flying back to zenith mode above the equipped vessel.

Question: What is the calculated efficiency gain compared to traditional sails and modern sails like wings and Flettner Rotors?
Basically, we advice the surface of the kite based on fuel savings of 20 % per year, but it can be way more as it can be less, depending on shipowners wishes. A kite can develop a traction up to 100 kg/m², a classic sail is around 10 kg/m².
@@beyondthesea-ypyou said: 2 people to launch it.. how will this work for bigger kites, for bigger ships ?
how launch it?
Wonder how much it can pinch going to wind.

@@beyondthesea-yp Merci pour vos explications c'est vraiment passionnant.
Ça ouvre de sacrées perspectives ..!
Try with 2... ..
Calm sea, light wind... And what if the waves rise to 10-20 m and the wind 50 knots? then sit and😭😭😭😭
Probably the team has already figured this out, because managing such a project shows some sense of responsibility?
We've already used the system in open sea conditions several times (for now 4 meters waves and up to 40 knots of True Wind Speed) with the 60 feet catamaran, and this is where we had our speed record with the 50 m² kite (20.5 knots) !
@@beyondthesea-yp impressive, lookin forward to see some footage of that!
I think the kit is a little to small for the size of this catamaran. Imagine with a bigger one.

@@beyondthesea-yp Can't wait to see that. Wish you a lot of fun and thank you for sharing.
Very interesting
Thanks !
Inventor: let’s invent a boat that is powered by the wind!
Friend: what about sailing boats?
Inventor: …
Épatant !!!
Effectivement, et ce n'est que le début !
Le french built some cool shit here. muy bien oui oui
Très bien, oui oui*
'Muy' is Spanish, if I may be pedantic ;)
Why do they call it "Le SeaKite"? Isn't there a French word for Sea Kite? 🙂
This is the name of our international product SeaKite, from which the cat is the desmontrator.
@@beyondthesea-yp Thanks,

@@beyondthesea-yp Plus cats are more popular than tris, so I guess it makes sense in terms of marketing. Nice video. 🙂
Next its on foils
Incoming in some years, but for now we focus on the development and the robustness of the automatic pilot for 100 and 200 m² kites.
now put a foil on it
L'idée a trente ans, au moins! Nicole van de Kerchove a traversé des Canaries aux Antilles comme ça en 1995. 😂
Effectivement, Nicole était une visionnaire ! La technologie du kite a depuis beaucoup progressé et les performances ne cessent de nous surprendre.
Re-batisez le Le StupideKite !
a little expensive
This depends on the price of the vessel you install the system on, but it is not expensive compare to fuel savings you can make with it.
@@beyondthesea-yp nice
Sur le bassin d'arcachon où la surface de navigation est très faible c'est n'importe quoi.
S’il s’agit d’un premier essai de cette configuration, et qu’ils connaissent bien l’endroit, où est le problème?
