Name: Phocea
Value: $11.72 million*

Tom Hanks and his wife, Rita Wilson, are big fans of sailing, judging by the fact that they rented the largest sailing yacht in the world (by 2004 standards, anyway). Hanks might have become famous for his role in Castaway, but he and his wife had a far more peaceful vacation at sea when they rented Phocea.

Phocea costs $200,000 a week to rent. Hanks and Wilson sailed the yacht along the Turkish coastline for their vacation. Phocea has been around since 1976. Prior to the 2004 launch of Athens, she held the title of “world’s largest sailing yacht” for nearly three decades.
