There is arguably no greater symbol of wealth than an enormous, gleaming, luxurious yacht.

Yachts are the ultimate toys for those who have out-earned the modes of common recreation. They offer privacy, extravagance, and comfort tailored to the exact specifications of the owner.

In the last decade, the uber-rich have entered into a worldwide arms race to build the largest, sleekest, fastest, most over-the-top floating toys a person could imagine.

The latest entrant, the gold-plated History Supreme, cost an eye-popping $4.8 billion.

The result is a veritable armada of money-soaked super yachts docked in ports across the world.
