In 2003, Paul Allen's yacht "Octopus" became the largest privately owned yacht in the world at 127 meters long. It cost $200 million and has a crew of 60 people including former Navy Seals. The yacht has two helicopters, seven boats, a 10 person submarine, and underwater vehicles. On average, yacht owners must spend 10% of the purchase price annually on upkeep and crew salaries, meaning "Octopus" requires a $20 million annual budget.
