Take a regular surfboard and strap this on.
It's the attached cross country ski machine on a surfboard. As you move your feet forward and backwards, it moves the two six or so foot long one way ribbed paddle mechanisms under the board forward and backwards pushing you forward. You steer with the
handlebars or poles which turn a rudder, probably in front as there's be a static stabilization rudder in the back.
So the motive unit is a board about one foot by six foot with a series of hinged paddles that extend out into the water when pushed backwards, and fold up when moved forward so they only physically engage and push in one direction.
I've come up with a real small version about the size of a suitcase. Slip it over the front, grab the handles you steer it with, step on the pedals that power the drive mechanism underneath take off.

Compact, straps on and works with any surfboard or paddle board. [doctorremulac3, Jul 07 2024]
World's more horrible illustration but gets the basic idea across.

As one who's never surfed a foot, would it be easy to balance as you stride and shift weight? |
|
| |
Was wondering that myself. I THINK it would be similar to a bike. I surf but that’s on waves where you steer by shifting your weight, this would be more of a paddle board thing that I’ve never done. |
|
| |
Surfboards are generally riggen sideways to allow the knees to bend to adjust balance and direction. This would be more like skiing and I'll bet would require flat water. |
|
| |
You might even want the design to allow your feet boards some degree of independence from eachother for just that balance reason. |
|
| |
Yea, I'm playing with various design tweaks that account for that stuff. |

Thank you for the patent link a1. To be clear, I do appreciate it when you point out aspects of ideas that have been done before, that's obviously useful and good to know. |
