BOAT!

[z1nyc]

As a biker, you need two things, a stiffer seat, (which needs to be brought up forward for the rider) and a much bigger chainring if you're going to stick with the chain system. I'm surprised out of all the videos of water bikes, almost none of them have a belt drive, being that a chain is vulnerable to rust.

What design flaw is causing the rider to keep leaning so much to one side?

With a better rider, what' kind of top speed are you looking at?

Wear a life vest :)

other than that great video

From what I've seen, I'm not really convinced that hydrofoils have less drag than a long sleek polished floating hull. Hydrofoils have much less surface area, but what they also do have is a lot more induced drag.

[lukepatrick2]

This little guy might not be the best example of hydrofoils reducing the drag of a large hull, but that's the entire reason they exist. It's definitely true, so get convinced.

awesome project. cant wait for the full product roll out!!!

Also, fyi, I'm in the USA

love the music!!

[rsboy5]

personally the only adjustment i could possibly see is put the seat like 6 in forward because u boat kept tippn back

[m1leswilliams]

Fantastic job, but the point of a hydrofoil is to remove the hull from the water to lower the surface area in contact with the water, looking at the size of the wing under the surfboard you haven't really gained anything. Smaller thinner wings would lower drag, increasing the speed, meaning they work better.

[lukepatrick2]

Indeed, but our design criteria required the size of those wings, and here's why:

The thrust provided by pedal power alone is relatively small, so the hydrofoils (wings) needed to have sufficient surface area to turn that small thrust force into a lift force equal to or greater than the vehicle and rider. The craft was designed for up to a 250 pound rider, so the size of the wings was necessary to achieve "flight." Smaller wings would produce less drag, but they simply wouldn't fly.

wow! good job people ;)

[ImTheMostViewed]

Looks cool but tiring...

[generatrix999]

Can't wait!

That seat is all you'd need- a frame with webbing.

The drive system is weak. A chain is not the way. Check out Natives 10:1 drive on their pedal Kayak, that would get you flying.

[koolaidbergaide]

get a stronger guy

[lotsoffun]

cool! nice job, adjust the seat lol

[IstasPuma]

Very awesome, congrats on the success.

I think it might be easier to make a canoe or a kayak and put a Minn Kota Endura 55 on it. It could do as much as 15-20 mph or more if you use paddles also. You'll still have balancing problems of course, but you might be able to overcome those by adding some type of low drag floating wing assembly, or a straight vertical panel under the boat, possibly both. Then you won't need to use your body to balance so much. What do you think?

[ShaggyBuffalo]

are you cavitating when rising up? seem to loose some power... ??? nice though! keep water flying!

[josetiburon2007]

BUEN INVENTO

[RichRuss1]

dudes that is totally awesome, my hat is so off you guys!!! I have an idea i'm working on myself, just on paper. Keep it up don't quit. You're going to do it! And as for the video awesome very inspirational, I love seeing people think beyond the box.

[goney3]

Great video, the music was awesome! ... I agree that the drag must have been a real drag, I can't wait to see the next version or concept. Cheers and well done! :)

[jensencharp]

Nice construction you got there! Im been thinking about constructing a such thing for months. So fun se someone have done it, and worked. Now I must make one too :)

[hadwer]

hey whats the name of the song at the second part of the vid?

ive heard it before, but cant remember the name...

i like your project more than the one that has the person bouncing up and down... this one seems more practical.

[lukepatrick2]

I can't remember the name of the song, but it's by Mocean Worker. And thanks for the compliment.

[sopwith74]

It's called Right Now, if you are still interested 6 months later. It is Mocean Worker, as lukepatrick2 said.

It appears that your "Shutt strut" leading floats are really digging into the water and slowing the boat down.

Also, there appears to be quite a difference in cadence between displacement and flying modes. There must be an awful lot of drag in displacement mode.

[lukepatrick2]

At the end of the project, the floats were among the top three items that needed improvement. There are plans to improve on this one, or make a new version entirely, but the above version was more than good enough for an "A."

As for the drag, reducing it was one of the key objectives in the design. There is a great deal of difference in the drag during displacement and during flight. This is one of the main reasons, if not the main reason, to employ the use of hydrofoils on any watercraft.
