Attessa is a private yacht owned by Microsoft co-founder Paul Allen. It is one of the largest and most luxurious yachts currently in existence, with some estimates placing its worth at over $200 million USD. The vessel boasts an impressive 500 feet of length and 11 guest suites, each featuring their own en-suite bathroom and shower, as well as an onboard gymnasium, movie theater, helicopter pad, swimming pool and Jacuzzi. Attessa's exterior design was inspired by classic J Class Racing Yachts from the 1930s era while her interior was designed to reflect contemporary luxury living standards. With its state of the art amenities and sophisticated design elements it's no surprise that this exquisite yacht has become one of the most sought after vessels for celebrities or royalty who wish to experience both opulence and privacy out on the open seas.
