The 331-foot behemoth before you is the Attessa IV, the superyacht currently docked at the Museum Park slip neighboring AmericanAirlines Arena in Downtown Miami. This beast of the sea with an estimated value of $250 million was renovated in 2011 by current owner and billionaire Dennis Washington, ranked as the 76th wealthiest person in the U.S. last year by Forbes. Besides a helipad on stern, the vessel boasts 10 cabins, a master suite, an ultra-modern stabilization system, movie theater, pool, jacuzzi, gym, spa, and beauty salon. Attessa IV is designed to comfortably accommodate up to 18 overnight guests and 26 crew.
Fun fact: Bill Gates took a family vacation on Attessa IV to Belize in 2012.
