Jessica Watson, a 16-year-old Australian teen, crossed the finish line of a round-the-world journey Saturday in her pink yacht after seven months at sea. She has become the youngest sailor to circle the globe solo, nonstop and unassisted. Thousands of spectators erupted into cheers as Jessica sailed into Sydney Harbour, the finale to an epic adventure in which she battled 12-metre waves, homesickness and critics who said she'd never make it home alive. "She said she'd sail around the world, and she has," a tearful Julie Watson said as she watched her grinning daughter cruise past the finish line from a nearby boat. "She's home." Jessica waved as she sailed past the finish line at the entrance to Sydney Harbour in Sydney, Australia, capping off a voyage of nearly 23,000 nautical mile. She gasped, laughed and waved her arms frantically as she caught sight of her parents when they pulled alongside her 10-metre yacht, Ella's Pink Lady. The teen was set to touch land for the first time in 210 days by docking at the city's landmark - Opera House, where she was to be greeted by throngs of fans, the Prime Minister and her family.
