The world's biggest ship is a giant so huge it's a city at sea. In this episode we chart the quest to conquer the oceans and take a close-up look at the biggest cruise ship in the world, Voyager of the Seas. This giant is the length of 3 football fields and will rise over 200 ft above the sea. From design to delivery it's a story of risk and revolutionary new technology set against the backdrop of the intense rivalry between cruise companies, and the historical story of the rise of the great liners.
