Boats waiting for the tide

 This photograph, taken in Ireland, is a reminder of how important the sea is to some communities, where people make their living by fishing, or where by boat is the easiest or sometimes the only way to travel. This is not a pretty marina of expensive yachts such as you might find in the Mediterranean, but a working shore where people depend on the boats. The images make a tricky game to see if you can find the differences.
