33. Not Originally the RMS Titanic
Many consider the Titanic a cruise ship. This is likely due to the fact that it was built to be a luxury ship for passengers. The first use of the word “cruise ship” or “cruise liner” was in 1900 with the luxury cruising ship, Prinzessin Victoria Luise. But many point to the fact that the Titanic is actually a Royal Mail Ship (which came with the benefits spoken about earlier), but that was not the original designation of the vessel. Originally, the Titanic was going to be called the SS Titanic. SS stands for Screw Steamer, also known as Steamship, but after carrying Royal Mail, it gained the RMS title.
Was it a cruise ship? That is up for debate. It wasn’t ever called a cruise ship, but it was also considered a luxury liner. Ultimately, the ship pulled double duty as an RMS and passenger luxury liner.
