Name: Sybaris
Value: $300 million 

Billionaire Bill Duker is the owner of a 230-foot superyacht, named Sybaris, that is the sister yacht to the fifty-two meter Feadship yacht Rasselas, which he also owns. The Sybaris is the largest superyacht ever built by Perini Navi, an Italian company. Duker described the yacht as “the boat of his dreams.”

It has two masts and won the title of Best Interior at the renowned Monaco Yacht Show. Duker came up with the concept for the modern interior twenty-two years ago when he and his son, West, would sail on the much smaller Palmer Johnson sailboat they owned.

The former Manhattan-based lawyer Duker initially carved out his fortune as one of America’s leading antitrust experts. Later expanding into venture capitalism, Duker has since made pricey purchases both at sea with this yacht and on land in real estate.
