22. Mohammed bin Rashid Al Maktoum’s Dubai
The ruler of Dubai owns the third largest yacht on the planet, dubbed the Dubai (creative, right?). The yacht is 534 feet long, can hold up to 115 people, and is controlled by a crew of 88 who stay onboard. Like any other person of royalty, Al Maktoum only wants the finest amenities on his ship. Some of the most amazing features include a helipad, a humungous indoor gym, and a swimming pool.
