Forming their own modern-day armada, four members of Spain’s royal family competed in sailing at the Summer Olympics. In 1972 Juan Carlos I finished 15th in the Dragon class. Twelve years earlier, his future wife, Queen Sofia, was a reserve member of the sailing team for her native Greece. Then in 1988, their daughter, Infanta Cristina, sailed for Spain at the Seoul Olympics, where she carried her country’s flag. And four years later, her brother Felipe, heir to the throne, also sailed for his country and was the standard bearer at the opening ceremonies. No one in Spain’s royal family has won a medal.
