Look at the tickness of the board, seriously doubt it floats enough to stand on and I cant see it working fully submerged with a rider standing on it and magically surfacing like a submarine either. We just need more details instead of speculation
Submarines can do that because they donāt have a giant human standing on top of them.
Starting with a board underwater is not an easy task even when you have a ski rope to pull your COG back forwards once you start getting the board out. If you then remove the rope thereās nothing to actually shift that center of gravity back forwards.
Another big issue is do you really want to be strapped in to a board thatās got no flotation? So itās actually just an anchor?
@Jezza, Please dont put him off building this. I want to see him riding the non buoyant efoil. 
Cmon, take him seriously. after all, he did ride a push bike around some old boat yard. this has to be legit right.
MK2 might have an inflatable ring as a training aid.
Hmmm. This guys machine may not have the mechanism ,but if he can maintain to stay upright till airborn than all else is equal to an e-foil.
Simply the the floating board is just an apparatus to stay vertical and plane till airborn.
Just trying to be constructively open minded.
His machine has no bouyancy so it will just sinkā¦
It will be like attaching chains with a motor to your feetā¦
Ill speculate that it has atleast neutral bouancy.
If none than probably sinks like his dreams.
Yes it will sink but it is not final and thatās why I am still reading this post (we already had this conversation around post 10 of this thread 
)
A wake / kiteboard has no buoyancy. However with a bit of speed, its bottom surface (1.4 x 0.4 = 0.5m2 = 5000cm2) receives a lot of lift from the water. You can feel it with your hand palm moving fast on a water surface. So we can see the Supernova board as a biplane: a 5000cm2 front wing over a 1300cm2 one. I donāt see why such a craft would not be water borne at ultra low speed with a rider lying on it.
The rider can also have a floatation vest to have time to reach that speed.
IMHO, the following situation is doable even without Gyro Balance System works. Then, to reach the standing position, a GBS is preferable. If I remember correctly, @waterfox managed to stand up on a 30 litre Takoon kiteboard without GBS using the following technique.
And how exactly are you supposed to lie down on it when he has big boots attached to it?
That is why I mentioned āSupernova boardā on purpose. The above starting solution isnāt compatible with the Flyshoes board with boots.
IMHO, if the Supernova takeoff is doable, the Flyshoes takeoff without a pontoon or without a towing boat is extremely difficult if not impossible.
You need a bigger surface below the boots. Then there is the (huge) body/leg drag to minimise since the motor is only 3.5kw.
Standing up from a sitting position on water skis, snow skis, ice skates with boots is not so difficult providing you have enough lift below your feet. In water, if this minimum lift induced by speed (as above case) doesnāt reach your weight + the board weight you sinkā¦ And this lift arises only with a minimum speed and all the more earlier there is a minimum board surface.
With a floatation vest one could start in a squatting position when pressing the remote trigger (still too much drag), like. That is where a small surface under the boots would have been handy and this detail still does not exist.
You just donāt understand the fluid dynamics of deep water starting!!! You can not compare kiting, watersking or any other sport that has a rope/line that pulls you out. It hugely alters the center of gravity and allows you to completely unweight yourself and lean back to bring the board out the water.
With an efoil, the lack of rope and motor position make it completely impossible.
Thereās only one way to start with a small strapped board thatās very low volume.
If this wasnāt the case Chris from pwrfoil would be foiling just on the small pods that fit under his boards, but instead he needs the extra board to get up!

I think if you have enough power and skills you can use your body ( as a board ) to get the correct angle on the foil : foiling on a wakeboard can be done I think
Just like jet flying shoes I can go from under water diving , bodysurfing or straight in the air ( 8m) , just takes good balance and a lot of power
Foiling shoes are an another thing 
I like the idea. So maybe like a human torpedo. When having enough speed one would breach and then spontaneously pop unto a foil .
So true, it can be and has been done on this forum in deep water starting.
Image proof for the most sceptical among us who pretend to know the fluid dynamicsā¦ 
This is Robbie Edwardsā demo, aka @waterfox who in 2017, that is 2.5 years ago, experienced what other people think impossible today in 2020. For me, Marc Lagarde watching this (yes I think he is a silent forum member) understood the possibilities of tiny boards and pushed the concept to its limit. Battery size and location are not the point of all of this.
Robbie shows us how to stand up on a efoil board with no to little volume: a Slingshot Dwarfcraft, 4ā6 25.2 litres to be compared with our 100-120 litre boards that were so far the admitted standard.
The early days, with misplaced footstraps (too far back) and wires along the mast making the efoil very unstable. Special attention required at 1:01, 1:29 and especially at 1:41 where the body starts behind the pulling board in deep water.
At 2:22 we can see that the board sinks with the rider standing on it when the board is still.
11 months later, same board but strapless, motor cables inside the mast. Deep-water start method described at 0:00 and 2:30: the rider relieves the weight on the board by taking the legs out of the board.
With a no volume board, a floatation vest can make life easier.
The good news is that @chris from pwrfoil can now foil just on the small pods that fit under his boards, the extra board becoming an option to get up!
Of course, this method cannot be applied to the flyshoes since the rider has boots and no surface underneath.

Hi Guys, I have a video of the prototype in action. I am just like you guys, keen to see this work. I am confident that it will. let me just point out that I sell many products, I have my own business and am just very keen to sell this board so my bets are on that it will make a go.
If it does, we all happy. My interest in the board is to be a seller.
Marc have been in the boating industry for many years, they are reputed in france and I have seen the racing boats and all that Marc has created. his workshop is more like a factory. He has very high tech equipment and is a qualified racing engineerā¦ It is packed with awesome boats. he decided that his passion lied in developing these water toys.
I get a walk through by video live daily, I have seen the technology from 3 D printers to stuff I really do not even know bout as I am a seller, and respect all you guys for your passion as I have not the technical skills that you have.
Guys, please give it a chance, I know that it seems too good to be true but you guys will I hope see the results.
I do know the answers to most of your doubts but am sworn to silence at this stage. I just want the products to be a success from a reseller point of view.
Please just give it the chance to be unveiled, and perhaps then we can all learn something from this.
I have seen quite a few brands start and then vanish and wasted a lot of time promoting them, I am not here to promote and neither is Marc Guys, he knows that he will surprise everybody and his credentials are good. He is actually a fanatic, starts at 6 am and works till midnight. A nice chap as well to be very fair.
Lets see what he comes up with and I would love to share more but have be asked to keep it quiet until the launch, but there will be video before as nobody is going to travel to Paris before seeing the board in action on the water and marc fully intends to do that.
as I said, I take my hat off to you guys working out all the specs but I am not an engineer.
I apologize for getting off on the wrong foot with you guys but I really believe he will pull this off and i am very hopeful to be able to retail the board when they are manufactured.
Cheers for now, as soon as I am authorized to do so, I will post here if you want the board in action, then would be the appropriate time to really analyze the technology and performance.
Cheers for now Guys

I can, and I would love to post a recent video trust me. It is on the water and then back in the workshop, continous improvements, absolute perfectionist. professional footage will be released when marc is happy with the product, as it is, it is good to go, but Marc just continues to improve it. i will keep you in the loop as soon as I am authorized to post a vid guys I promise you that. Take care
I think I heard enough of it.
Dunno what it is accomplishing, but in this situation I rather lean on science than faith.
B.S.
If you had a video you would post it. Just more of the same excuses.
October 2017 , Peter used a 20L board with a small motor geared set up
Yes it can be, but its WAY harder than using a higher volume board. You also have much larger power force pulling you with a rope. VERY different to having a motor 60cm below you.
Please attach a foil to your jet flying shoes and try do them at the same time 
Robbieās board was a 5ā6" Dwarfcraft which has 36L of volume (Hereās the board https://www.jupiterkiteboarding.com/store/2017-slingshot-simulator-56-foilboard-p-6374.html)! He was riding it with a small battery and clearly stated in his build thread that if he wanted a bigger battery he would need a board with more volume.
So why didnāt he then start standing with it deep if its going to be possible for Marc to do it? Oh waitā¦
No, he hasnāt foiled with only the small podā¦ Heās always had a board attached to the pod.
No you definitely do not! The second Marc proves his concept he will flood Facebook and every forum he possibly can to prove everyone wrong.
The Naish Hover 160 is a 25L board. Its also 160cm long which means a much larger planing surface and much easier to stand up on than a Ā±100cm.
If guys really want to compare, find a 100cm low volume board and try do it. Or strap a battery pack between wakeboard bindings and go prove me wrongā¦
Just to bring another bit of information:
a couple years ago, i wanted to do a transparent foil board, but as it didnāt seem very practical i settled for making one with the lowest possible surface.
It works great with a kite ā¦ if you can take off.
only way to get going is being overpowered and takeoff straight on the foil without planningā¦and if the āboardā touch the water, youāre done.
without straps, starting with the board fully under water wasnāt really possible, so i canāt comment on thatā¦
note: the kite pulls more than our motorsā¦ and help stabilize the whole thingā¦
