So, I am thinking of a robust piece of C channel running up the piling
through bolted to the piling every 6". A piece of metal is free to
run up and down in the channel and it has a threaded hole into which
the thread of an eye bolt screws. You tie your dock lines to the eye
so the boat then rises and falls with the tide as the metal T in the
channel rises up and down pulled by your boat.

I'd bet good money that your arrangement would bind under load.
Instead, take a length of steel bar (square or round). Put a 90
degree bend in each end to serve as a standoff. Place a plain old
ring on the bar. Weld a base plate on each end of the bar. Bolt the
bar to the piling. Tie your line to the ring. No problems with
binding, zero maintenance. Good luck with the storm.
