LONDON -- The sea voyage that changed Peter Padfield’s life more than six decades ago started with an act of chance. In 1956, Padfield was third officer aboard a British cruise liner in Sri Lanka when he stumbled across a magazine in a ship wardrobe.A story inside introduced Padfield to a new sailing ship dubbed the Mayflower II, a replica of the square-rigged English merchant vessel that carried a group of dissatisfied Protestants across the Atlantic Ocean in 1620.
