The Saudi royal family is estimated to have a combined net worth of $1.4 trillion (£1tn), making them the world’s richest royals. So it’s no surprise they own one of the largest superyachts on the planet, the Prince Abdulaziz.

At 147 metres (482 feet) long (including helipad), it was the longest in the world until 2006, and with 65 crew members it can accommodate up to 64 guests. The yacht is estimated to be worth at least $100 million (£76m).
