Luxury vessels take up eight of the top 10 slots, with the world's largest mega yacht, the Azzam, ranking at the top of the list.
The 590-foot yacht was purchased in 2013 for a reported $627 million by the ruler of Abu Dhabi, Sheikh Khalifa bin Zayed al Nahyan – a price that would mean the vessel is worth around 3.5 percent of the Sheikh's his net worth of around $17.9 billion, said Wealth-X, which researches the ultra-wealthy.

Owned by Russian tycoon Roman Abramovich, the Eclipse was ranked number three on the list of most expensive luxury assets, coming in at around 4 percent of the total estimated net worth of Abramovich.
