The mega-yachts they are talking about are not your typical powerboat that you can park in your local marina. These are monster boats that take nearly four years to build and can be longer than the State of Liberty is tall.
One of the most famous Mega-Yachts is the Octopus (pictured above) owned by Microsoft's Paul Allen.
Here is YouTube video of the Octopus posted by YouTube user etb92.
The Octopus is the world's sixth largest yacht and comes equipped with its own submarine.
The world's largest yacht, The Eclipse, is still under construction.
