UHMW for structural pieces

While I have used UHMW for several shims/pads with great success, I did wonder about rigidity and compression characteristics for some applications. For instance, I daydreamed about the idea of replacing my PITA teak coaming boards with white UHMW (tacky, I know, but easy to clean!) but I was dubious about whether they would resist bending (the aft 1/3 of these boards are pretty unsupported).

However. I happened to spend some time in a bathroom stall that was completely constructed of 5/8" UHMW -- sides, doors, everything. I did some testing. It is pretty darn rigid!
