Very very poor man's DIY endless pool idea

[bioguy]

I swim tethered in my 21foot agp and find that I generate a lot of current. If I time it right, I get some pretty good sized waves. So I got to thinking, what if I could divert the current so that it was all directed to return to my head end. I'd need some kind of barrier that I could sink into the water and preferably remove easily so that I could take it out when the kids wanted to swim.

I need ideas for what to make the barriers out of.
Below is a sketch of my design idea.


Or maybe even just the two walls like this:


Do you think the extra curved walls would add anything?

I also figure I'd orient it so that the pump input is at my head.

Thanks for any help you can give me.

It might be easier to put a diffuser right behind you so there is not a collimated stream of water going backwards. Maybe a triangle or a half dome.

I agree with Mark that a diffuser of some sort is probably what's needed. At the moment the circular wall of the pool is effectively focusing any waves right back at the source (you).

As for material I suspect that some sort of sheet plastic is the thing to use, acrylic or Lexan or maybe even the twin-wall polycarbonate used for green houses. Glue or tape a pool noodle to the top edge as a float, and tether the assembly to the edge of the pool somehow. The assembly probably only needs to be 2-3' deep.

So something as simple as this?


That's pretty easy.

I have some Plexiglas I dug out of the dumpster when our school got rid of all of the dividers between kids seats. I'll try that with some pool noodles and weights to keep it in place.

Yep that was the idea, and sounds like it will be pretty cheap to test if you have the Plexiglass available!
Let us know if it works and post photos!
