Sebastian Clover is a 15-year-old boy who lives in the south of England. In January, he became the youngest person ever to travel from one side of the Atlantic Ocean to the other, all along in a sailing boat.

It took Sebastian twenty-five days to sail from Tenerife to the island of Antigua in the Caribbean. This isn't very quick, but it is a long way for a person who is so young.

The weather was fine during Sebastian's trip, which was lucky, he wasn't always alone. Sometimes very large fish swam next to his boat. At first he was afraid that it was dangerous, but the fish was very friendly.

The main problem that Sebastian had on his trip was when his telephone stopped working. His parents worried about him, because he usually phoned them every day, but for the last three days he couldn't. Sebastian was sorry not to talk to them, but nothing else was wrong.

Sebastian kept a video diary on his trip. You will soon be able to buy this video in the shops. Sebastian wants to sail around the world next and he doesn't have money for it. If you buy his video, this will help him.

1) Sebastian is a 15-year-old student from England. 2) Sebastian sail in the Atlantic Ocean in a boat.

3) Sebastian spent more than a month in the ocean. 4) Sebastian started his trip in Antigua.

5) The weather was pleasant during the trip.

7) Sebastian was lonely because he didn't have a telephone with him. 8) Sebastian had a camera with him.

9) People will be able to watch it in the Internet.
