Hi,

I recently painted a design in acrylic paint on a piece of maple wood
that will eventually be subject to elements such as UV, weather, foot
traffic, etc. I've heard that marine polyurethane is the way to go to
protect this sort of project, but I'm having a heard time finding one
that is water-based and would not smear my acrylic paint.
Is any water-based polyurethane (I've found some with UV protectant)
going to do the job?

You provided a brief description of how it is going to be exposed, but
what it actually is could help in determining a finish. Some of the
epoxy resin coats might be what your looking for such as this one

On the other hand, if you are creating some time of "stepping stone",
this wouldn't work. Also, some poly's will begin flaking, turning
yellow, and fading in direct sunlight.
It might help if you give us an Idea of what use it will be seeing.
