Another production by Lurssen Yachts, this luxurious boat beats even Dilbar at its own game due to its exorbitant approach. This goes without saying as Azzam was purchased at the price of $650 million, which is almost three times the price of Dilbar. The President of the United Arab Emirates and Emir of Abu Dhabi, Sheikh Khalifa bin Zayed al-nayan recently purchased this luxury liner. The makers of this luxury yacht claim that it is the most challenging and complex yacht that has ever been built. This can give us an idea about the durability and high quality of the boat as well. The 590 feet long yacht has attained the position of the largest privately owned yacht in the entire world. Despite its humongous size, the superyacht boasts of crossing the fastest running speed of a yacht that is more than 30 knots. The interiors have been given a sophisticated yet luxurious finish by the French interior decorator known as Christophe Leoni. He states that the interior has been inspired by the century Empire style of living.
