The Hydrofoil Kayak is build by Leif Wagner Schmidt and equipped with electric drive by Ole. The video is recorded at Force test facilities in Lyngby, Denmark.
The main wing they used was too small, it needed a longer cord length. They were trying to reduce drag but the main drag reduction is to come from lifting the boat.
Does anyone remember the foiled double hull, bicycle cranked, upright rider propeller driven from the mid 80s? it was featured in Scientific American on the cover of one of their editions. Someone made a few, modified from the original prototype and sold a few. They were good for a sprint up on the foils, but slower pedaling and they would settle back down on the hulls.
Theres a few different ways you can do it. The simplest is by having a chain which connects to a sprocket up top and goes through a hollow chamber all the way down the mast which connects to a sprocket on the propeller shaft. This chain would need to twist 90 degrees like a Möbius Loop. Another way is to use 2 gearboxes which use bevel gears at the first 90 degree turn the drive train needs to make up top to change direction downwards, then a drive shaft down the mast and then the 2nd gearbox to change direction horizontal which would drive the propeller shaft. A third way would be universal joints but I dont think this is ideal because the rotation of the prop would be oscillated instead of constant with the rotation of the crank(foot pedals)
Это же можно сделать механизм, при вращении педаль ты заводишь его с принципом детской машинки и отпускаешь их.. и потом когда останавливается, снова крутишь педали заводя механизм) или как электрический движок заряжая
Вундервафля какая-то, как долго и с какой силой придется крутить эти педали чтобы на крыло подняться? Продержаться ощутимое время - наверно только велоспринтер какой-нибудь сможет. Ну и вес тоже больше чем у обычного каяка. А испытывают на стенде, так как не смогли найти такого спринтера наверно....
Just because stabbing warrants extreme fear does not invalidate fear of freezing water... You just made a logical fallacy :-) Aside from which, he looked to me like a man with limited space to complete something technically challenging, he was concentrating!
shotgunsurgeon789 Ever fallen under a boat being cable dragged? Put all your macho posturing aside and consider that fear operates on a scale... He might not be terrified but fear in this situation is healthy, although I still maintain that he's simply concentrating! Slow burn_172 This is the YT comments section, did you expect anything else?

There are a lot of geometric deficiencies happening that prevent this one from being practical..
That high speed face is priceless...
Thats one high tech braking system ;)
the first time i tried kayaking i probably went half this fast and i was breathing like a ramjet air intake
He's using a motor btw
...you weren't breathing out? How?
@@AnimeSunglasses Halarious, Thank you sir
@@duckieyoutube I bow graciously, sir!
Half this fast? Bloody hell, that was a good effort mate. I'll sell you my Tasman Express sea kayak if you're looking for one lol.

Well. Back to the drawing board. Good effort though.
Great to see testing! Thank you!
damn his legs are so fast like the helicopter blades looking like they're not moving at a high enough frame rate
This is actually exactly what I wanna make. Could you show a video of how you transfered power from the cranks to the propeller

Thought he was testing a kayak.
Sounds kicks in... and he looks like he feels that he’s being launched into another dimension.
Translation: "I'm wearing jeans to test a boat and this was a shit idea and what the fuck is that bridge doing there?"
Hobie did this with sailpower and essentially a kayak two decades ago. Cool but now new!
You may be referring to the Hobie Trifoiler? It was based on the Longshot developed by Greg Ketterman.
Where was this filmed?
get out on a lake or canal with that
obviously need more speed
put a sail on?
Will it have more than 1 ⚙️? Very cool
Doesn't look good to me. Too high speed and too much power required to keep that pace for any practical amount of time.
Looking for follow up & progress updates! Bring it!
I can hydrofoil a school bus if I've got a fast enough tow rope.
that would be awesome lol!!
Looks like they are in an old U-boat pen.
Danach suche ich für mein Boot 😉 Beeindruckend!
Why does this look like a video game cutscene at first?

Kan ikke vente til vi ser sådan nogle komme flyvende before ude på jorden :D
Good...thanks...
All boats should be hydrofoil
You are from danmark you are speaking danish
keep it up
The Polynesians sailed across the Pacific with one foil.
and this is good for?
Nothing
You just need Mark Cavendish!
More like 5 marks
Someone got the marlin

no helmet as he races toward a steel girder.
It’s too slow to,ride on the hydrofoil.
Next, open water testing...
Next, ab electric motor...
🤙🤙
Mouhahahah le type le plus à l'aise du monde!!! 😂😂😂

wOW... kayak hydrofoil decapitation.
This video Collab with John Cena does not have more views than his other videos....
Don't you hate it when you run out of lab 🙂
Kayak? More like Flyak! Amirite?
Hum ,only on flat water in the lab
In reality water is not calm n flat
Just be thankful Justin Y. wasnt here
Well, A for effort i guess...
No bueno
Clickbait.
Faster
Hydrofoil too dangerous for animals,of security element need now!,best model game for kids... :)
Я то думал краш-тест
Outrigger canoe.
Какие то брызги...
He looked scared as hell !!! It's only water ya sissy
The water is probably really cold and he wasn't wearing a dry suite so, yeah, fear is warranted. Lol.

You guys are NO fun, how can you take a simple humor related statement and turn it in to technical argument !!??

falling off a boat being cable dragged? big fucking deal. try catching an edge wakeboarding.
Nobody can pedal that fast... thats why he wasnt doing anything.
One big joke
Looks like fun. How did you get access to the Force towing tank facility Stig @stigantonnielsen ?
it sucks. better go back to the drawing board tjat will never handle in waves
