I took this picture at the harbour of Svolvær last summer. The chain is a bit rusty, but I assume it does what it is supposed to - whatever that is. Well, I suppose it's related to something like keeping the boat at the harbour.
Photo details: EOS 30D with my EF 70-200 F4 L at f/4.0 with a focal length of 104 mm. With ISO at 100, the shutter time was 1/500 seconds. The picture has been slightly adjusted and cropped with PhotoShop Elements.
This picture is part of my Lofoten set at flickr.
