Libby Purves explores the tempestuous life of the people who sailed on the last commercial square-riggers -the giant sailing ships that braved Cape Horn to bring cheap Australian grain to Europe. She traces some of these ancient mariners, women as well as men, to hear stories of death-defying adventures, superstitions and storms in which crew members had to work on rigging as high as a Church Steeple. Producers Philip Sugg and Michael Weigall
