TEV Rangatira was a roll-on/roll-off vehicle and passenger ferry launched in 1971 for the Union Steam Ship Company of New Zealand. She is significant for having been the World's last surviving ship with steam-powered turbo-electric transmission. (Modern turbo-electric ships, including and Millennium-class cruise ships such as Celebrity Millennium, have gas turbines.) After a failed attempt to convert the vessel into a cruise ship she was scrapped in 2005.
