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 passenger ship with steam-powered turbo-electric transmission. (Modern turbo-electric ships, including RMS Queen Mary 2 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.
