The Tatoosh

Do you have $172 million to spare? If so, and you're the type of guy or gal who loves pleasure boating, billionaire Paul Allen has quite a deal for you. The Microsoft co-founder has placed his massive 303 foot yacht, The Tatoosh, up for sale, through Fraser Yachts.

The boat is truly impressive. Built in 2000, the yacht features nine guest rooms and two staff cabins. In addition to two helicopter pads, the steel-hulled yacht features a swimming pool and cinema. It can accommodate 24 guests and 35 crew members.

It's not like Allen is giving up his yachting hobby altogether. Remember that he's also the proud owner of The Octopus, a 414-foot sea craft which is among the largest in the world.

A spokesman for Allen confirmed that The Tatoosh is for sale, but declined to comment further or offer an explanation.

Forbes recently ranked Allen -- who was diagnosed with non-Hodgkin's lymphoma last fall -- as the 37th richest person in the world with a fortune of $13.5 billion. He's been falling on the Forbes list in recent years in part due to failed investments in companies such as Charter Communications. (In 2007, he was the 19th richest person on the planet).

Here's a pretty hilarious video of man who's awfully excited to spot The Tatoosh, which he calls a "monster."
