SS Nomadic

SS Nomadic is a former tender of the White Star Line, launched on 25 April 1911 at Belfast, that is now on display in Belfast's Titanic Quarter. She was built to transfer passengers and mail to and from the ocean liners RMS Olympic and RMS Titanic. She is the only surviving vessel designed by Thomas Andrews, who also helped design those two ocean liners, and the last White Star Line vessel in existence today.
