Aaahhh.... the dreaded 'GRONK'!
Tying the boat up with a bit of slack can help ease this some.. but if there's wave action or strong breeze you'll eventually fetch up with tension again anyhow.
We've found the worst for noise was using low stretch line (like old sheets) for mooring lines. Good nylon seems quieter. Cloth rags under the contact point reduced the noise as well. In extreme cases I've mover the lines to stanchions and pulpit bases to avoid the 'dragging' line through a chock or fairlead/hawse, but you need to be sure it's adequately strong. A bowline loop on polished stainless will 'gronk' much less than a round turn and hitch, which will tend to 'roll' around the post with alternating tension.
Tough to sleep through, that's for sure!!
