Name: Cyan
Value: $11.5 million*

Constructed by one of the most prestigious ship-builders in the biz (the Italian-based firm Codecasa), Bobo’s impressive yacht Cyan comes with a surplus of seaworthy treats. Onboard jet skis, hot tubs and an outdoor movie theater are just a few of its luxury features.

But the U2 rock star added his own personal touch to the craft: a state-of-the-art stereo system that runs through the entire vessel. He also added his favorite color, blue, to the ship’s exterior – and threw in a grand piano on the deck, too.
