     What do 17-year-old boys usually do ? Play computer games, read books or play basketball? But to

Zac , all interests in   his  life are from the sea. He is a 17-year-old  US  sailor.   After  a   hard 13-month

voyage, he and his 11-metre sailboat arrived at a Southern California harbour. He becomes the youngest

person to sail around the world alone.  

     When Zac was just a child, he had a dream-driving his own boat to travel around the world . so he

saved all his pocket money . When he was 16 years old, he had 6,500 dollars. He bought a sailboat, and

started his journey with the support of his father, a ship builder.

     On June 14, 2008, Zac left Marin Del Rey, south of Los Angeles, and celebrated his 17th birthday at

sea near Africa's Cape of Good Hope.

     During his 28,000-mile journey , he came over many difficulties. When he came back home , he was

welcomed by a lot of people. It is said fewer than  250 People  have sailed around the world alone. The

number of reaching the top of Mount Everest is three  times as large  as the number of sailing around the

world alone.
