Azzam is a luxury superyacht built in 2013 by Lurssen Yachts, and commissioned by the royal family of Abu Dhabi. Measuring 180 meters (590 ft) in length, Azzam is the world's largest and most expensive private yacht ever built. It was designed for entertaining an exclusive group of VIP guests and it requires a large crew to operate. The exact size of the crew on board Azzam is not known due to privacy reasons, however some estimates put the number at around 60-70 people including officers, deckhands, engineers and stewards. This would be larger than many other similar sized yachts which usually have between 40-50 crew members. Additionally there are reports that suggest this number could even reach 100 when taking into account security personnel as well as additional staff such as chefs or masseuses. In any case Azzam certainly has one of the bigger crews among its peers and it shows how seriously they take their commitment to providing first class hospitality services onboard their vessel.
