Rope knotted around wooden boards on a boat

This is on one of the boats used for trips to the Farne Islands from Seahouses harbour. I took it on the way back from a visit to Longstone Island on our holiday there in August 2013. I think this rope was holding one of the life rings onto the side of the boat. This might be just me being odd, but the textures and shapes just appealed to me!

I increased contrast, reduced exposure slightly and converted to monochrome in Lightroom.
