A rivet-covered bronze sculpture with the face of a man and the body of an industrial-age ship, The Navigators is actually an enormous kinetic machine. The 60-foot sculpture by artist David Kemp was installed in 1987 during the renovation of Hay's Galleria, which saw the conversion of the old wharf into a shopping center. When activated, its oars move through the water at its sides. Kemp is a British artist best known for his large assemblage sculptures. He lives on the Atlantic coast.
