Azzam
Azzam is a private super yacht built by Lürssen Yachts in Germany. On April 5, 2013, Azzam was introduced. It is the world's longest private motor boat, measuring 180 meters in length. It has a beam of 20.8 meters and a draft of 4.3 meters, which is unusually shallow. The yacht was completed in three years after a year of engineering, according to Superyacht Times, which is a world record. Azzam is capable of traveling at fast speeds in shallow water. This is one of the most expensive yachts in the world.
Azzam has a main salon with a length of 29 meters and a beam of 18 meters, as well as an open plan with no pillars. It can reach speeds of over 59 km/h (37 mph) thanks to a combination of two gas turbines and two diesel engines that produce a total power output of 35,048 kW via four pump-jets. Two of the pump-jets are non-movable spherical water outputs in the stern's center, and the other two have thrust vectoring capabilities and are located on each side of the non-movable ones.
