3. Dubai

Dubai comes in at number three with a length overall of 531 feet 6 inches. Dubai, which has also gone by the names Platinum, Panhandle and Golden Star, got off to a slow start. Originally commissioned in 1996, the yacht was started by a partnership between Blohm + Voss and Lürssen but production was stalled for a number of years. She was finished in 2006 by Platinum Yachts after being bought by the government of Dubai, hence the new name. Among her many water toys, Dubai reportedly carries her own submarine.
