Blog_AdmiralYacht Designed by Monaco-based, Dobroserdov Design, the ADMIRAL X Force 145 luxury mega-yacht may possibly be the most impressive and outstanding yacht of her size, not to mention, the most expensive. The concept vessel is reported by The Daily Mail to be worth more than $1 billion USD, making it potentially the most expensive mega-yacht in the world. That is, if it is built before 4Yacht Inc.'s Triple Deuce which measures in at 722 feet and is set for completion in 2018. Blog_AdmiralYacht3 Resembling a luxury hotel more than a yacht, the X Force features crystal chandeliers hanging above indoor pools, solid marble floors, two movie theaters, 2 helipads and a duo-level beach club and spa designed for entertaining by day and night. The length of two jumbo jets, the X Force is for the most discriminating of VIP guests. Offering sensational floor-to-ceiling panoramic views, the X Force 145 confirms the placement of The Italian Sea Group at the top of European shipbuilding.
