The world's sixth- largest yacht is also one of the oldest super yachts still in operation. El Horriya was originally built in London in 1865 for the king of Egypt, and the length was extended in 1872 and in 1905 and last refitted in 1987.
The yacht is berthed out of Alexandria, Egypt, and is listed as a training ship by the Egyptian Navy. It can carry 160 crewmembers.
