Enough about Tiger Woods‘ love life… Let see his yacht. Tiger Woods owns a 155 ft. power yacht that goes by the name “Privacy”.

The yacht was purchased in 2004 from Christensen Shipyards, and is a 155 Trideck Motor Yacht with a reported cost to build of $20 million.

On deck is a large bar, stainless steel BBQ and an 8 person jacuzzi. A $150,000 station was added to fill scuba tanks with a blend of helium, nitrogen and oxygen.

Forbes magazine has announced that Tiger Woods is the first athlete to surpass $1 billion in earnings and endorsement money.

The magazine estimates that golf’s top-ranked player crested the plateau when he earned $10 million for winning the FedEx Cup on Sunday.

Woods has been the world’s highest-paid athlete since 2002 when he surpassed Formula 1 legend Michael Schumacher.

The beautiful singer and actress, Jessica Simpson has asked Tiger Woods for golfing lessons.

And sure, everyone would have as a golf teacher Eldrick Tont “Tiger” Woods! He is currently the world number 1 and he was the highest-paid professional athlete in 2007, having earned an estimated $122 million from winnings and endorsements.

Lucky Jessica has already signed up for a set of lessons, and has bought, for $8,400, a Louis Vuitton golf bag and some accessories to look always stylish, even when she learns to play.

According to Forbes, Golfing pro Tiger Woods will become the world’s first billionaire athlete in the next few years.

In 2007 alone, Woods earned $115 million, $65 million more than the second highest paid athlete, David Beckham.

Woods’ career earnings will hit the $1 billion mark by 2010 but given the taxes (45%), Tiger Woods should join the list of the world’s billionaires in 2011.

It will be an unprecedented occurrence. There are plenty of billionaires who have excelled at sports, but there are no billionaires who accumulated their fortune by playing sports.
