This $400 million super-yacht was built for a Russian oligarch, Andrey Melnichenko, 37, who is worth $9.2 billion and was ranked 172 on the Forbes list of the world’s richest people.

There is a large master suite as well as six luxury cabins for up to 14 guests and enough room for 42 crew members.

Designed by Philippe Stark, the 400ft long superyacht is said to have its own discotheque featuring a glass roof which is situated directly under the swimming pool.
