Q: When is a boat not a boat? A: When it's a story. In A Boat Retold, artist Ian Stephen, writer Robert Macfarlane and others tell stories in and around the restored Orkney boat Broad Bay, as it sets off for the Shiant Islands. The boat and its history become the narrative focus for movements in time over three generations, spinning tales of fishing, boat-building and family history - a ballad of Hebridean island traditions, experiences and arts.
