The 16-year-old girl Jessica Watson is said to be the youngest person to sail non-stop alone around the world. But her record has been questioned because someone thought that she has not sailed far enough. She will also not be recognized by the World Speed Sailing Record Council, as it was too dangerous for someone under 18 years old.

Ms Watson sailed into Sydney port on Saturday, seven months after leaving on a hard voyage. Family, friends and Australian Prime Minister Kevin Rudd have gathered to greet her. Thousands of well-wishers waited at the port and watched from boats as Ms Watson sailed her pink, 10m boat over the finishing line. Many more Australians watched the event broadcast live on television. Watson said she was just an “ordinary girl who believed in her dream”.

Ms Watson left Sydney on 18 October, despite that some people disagreed her plan. Watson traveled northeast through the South Pacific and across the equator (赤道), south to Cape Horn at the tip of South America, across the Atlantic Ocean to South Africa, through the Indian Ocean and around southern Australia. The route took her through some of the world’s most changeful waters, and she battled through huge storms and suffered seven accidents of her boat.

People around the world have followed Ms Watson’s adventures on her blog, which she has daily updated (更新). On her blog, she wrote down beautiful sunrise over seas, the excitement of meeting a blue whale and the bright, terrible sight of a shooting star flying across the night sky above her boat. Ms Watson has reportedly sold her story to a news company for $700,000. She is planning to write a book on her experience.
