     Imagine yourself on a boat looking out at the horizon and all you can see is the water meeting the sky

with no land in sight and you are sailing straight ahead to meet the world. Jesse Martin does not have to

imagine: he is living in it.

     On Dec. 7, 1998, at 17 years old, Jesse set sail from Melbourne, Australia on his boat, attempting to

become the youngest person to sail alone and nonstop around the world. He sailed south of New Zealand,

through the South Pacific, around South America, north on the Atlantic, back south past Africa, through

the Indian Ocean and back to Melbourne.

     Even as a young child, Jesse had been an adventurer who traveled all over Europe and Asia with his

parents. Born in Munich, Germany in 1981, he moved to Australia with his family when he was only two

years old. They moved close to a rainforest in Cow Bay, about 3500kms north of Melbourne, where they

built a small house with no electricity or running water. Jesse grew up at the beach enjoying the outdoors

to its fullest.

     At 14, he sailed for the first time with his father and brother, Beau. It was after this trip that he began

to dream about sailing around the world.

     Jesse's family played an important role. "I was made to believe I could do anything." he says. Although,

he says, there were others that were not so encouraging or supportive, "People that I looked up to, respected

and trusted told me I couldn't. Thankfully, I trusted myself. There were people that said that the boat

couldn't be ready by the time I had to leave." However, through perseverance and belief in himself he was

able to do what many told him was impossible.

     On Oct.31, 1999, more than 10 months after he set sail, Jesse Martin went down in history as the

youngest person to sail around the world alone, nonstop and unassisted.
