Rope tightening on docks

This is the setup, a fishing dock. There was this boat which sometime ago (a long time that is) used to be a floating gallery. Now it rusts here.

As I was passing by it with my bike, I heard the noise the ropes were making. The sea was a little wavy and this made the boat rock up and down thus tightening the ropes.



I placed my trusty H4 on the mooring pointing at the boat



The exact position of the sound is this:



Waves splashing are coming from here (apparently)
