#9. Lady Moura USD 210 million
This 344-foot mega-yacht is owned by billionaire Nasser Al-Rashid. It features a pool with retractable roof, a 75-foot dining table crafted by Viscount Linley and a helicopter. Lady Moura’s most remarkable feature, however, is the beach resort that slides out of one side of the boat. The mini resort features not only sand and deck chairs, but even includes palm trees for a truly authentic resort experience.
