Titanic II
There is, however, a currently ongoing project that will create a 21st century re-creation of the RMS Titanic. It will run under the new Blue Star Line and will have updated safety features such as enough(modern) lifeboats and azimuth thrusters for steering. However, the head of the project is trying to keep the design as close to the orignal as possible. Descendants of Joseph Bruce Ismay and Margaret Brown are also on the Blue Star Line board overseeing the project.
