In the movie "The Incredibles" there is a scene were Dash (one of the main characters) runs so fast that he actually does not break the surface tension of the water. This speed allows him to easily run across a giant pool of water evading his pursuers. Obviously a human is too slow to perform such a feat, but could a machine that simulates that speed be devised? I propose a modification to a motorcycle where the rear tire is outfitted with metal or rubber feet where upon when it rotates fast enough it could simulate the speed of Dash. This way you could determine the speed which a person would have to travel in order for them to run across water without sinking. Additional modifications would need to be made to the front of the motorcycle allowing it to float, possibly front skis to steer by, and adjustments so water does not enter the engine. Also, I propose a floating device that prevents the motorcycle from sinking and keeps it from dipping too low into the water. This way the rear tire is high enough out of the water that it can produce forward momentum. The floating mechanism will also prevent the entire motorcycle to sink entirely if a catastrophic failure occurs. This way multiple tests can be conducted without reproducing the vehicle for every attempt.
I have drawn up a facsimile of the device if you have any questions regarding the proposal.
Please contact me if you have any questions,

Respectfully,

What you are proposing is called a Jet Ski.

Or a Snowmobile.

I don't have a clever remark, at least you are thinking creatively and that might lead to something great .

Some time ago there was a man who made what can only be described as a triangular shaped hollow body wing , but I don't remember exactly what propulsion it used .

I must have seen the video perhaps 20 years ago, it was filmed on one of the lakes by Disney world .

Once it reached speed it would raise out of the water completely and glide on the air forced out between the wing and the water like a hovercraft , but without the cushion .

After I saw this video once , I never saw the craft again and I can't remember the name he gave it now .

There could be a practical reason it never caught on, perhaps it had stability issues in choppy water or he just couldn't sell his design to anyone .

It was wild though to see a girl standing on this thing and skimming over the water without creating so much as a small wake .

Please keep in mind it was filmed some time before photoshop existed .

I found out the design is essentially called a "wing in ground effect craft ". All of the images I can find are of large single or multi-person crafts .

His craft was small about the size of a jet ski with wings and you sat or stood on it , there was no cockpit and no huge propeller on the back .

I think it forced air through a small tunnel central to the device .

Yanko design has an image of something close , but not quite as small , there is no description for their image .

Is this what you are talking about? There are several similar designs for sale.

No, I have seen those before though .

This was a delta wing made of a flexible but solid material like plastic .

Had to be around 20 ft across in wingspan but it was much shorter nose to tail , similar to the popular kite .

It had something to provide thrust but it did not require very much before it started to glide just above the water .

And , there is a person on Youtube with a Suzuki motorcycle that appears to have some kind of outrigger device .

So I think your idea had already been tried Sundevil .

When I originally posted the idea, I was thinking of how fast would a human have to run so he did not sink in water. I thought of a devise that could possibly mimic that, but I’m not sure how you would compute for the weight of the devise, which would be considerably heaver than a normal human. Could a device be produced to mimic a human running on water is the real question?
