80-year-old sailor and journalist Jimmy Cornell starts his around-the-world tour from Seville to mark the 500th anniversary of Portuguese explorer Ferdinand Magellan and Spanish sailor Juan Sebastian Elcano's expedition that resulted in the Earth's first circumnavigation. Cornell is completing his expedition aboard the Aventura Zero catamaran for the "Challenge Elcano 500", a totally electric boat, and hopes to complete the journey in nine months.
