The Saudi Royal Family has set out to build the world’s largest private yacht. The $600 million mega yacht is known as Project Azzam, and measuring at 590ft long, it will be longer than some cruise ships.

Currently, the world’s largest yacht record is owned by Chelsea Football Club owner Roman Abramovich. His yacht, The Eclipse, is about 540ft long and features two swimming pools, two helipads, a gym, a hair salon, and a 007-style submarine.

Details of what Project Azzam will feature are limited, but we know that the fuel tank will hold over 1 million liters of fuel and there are only a handful of areas in the world that can accommodate a boat of such size, including Monaco and Antibes.
