These days Cruise ships come in all sizes and colors, but not long ago this wasn't the case.  To this day, when most of us see ships with dark colored hulls we think of them as more traditional looking, no matter what the age of the vessel.  Why is this?  Well, it has to do with how these great ships are powered, and the letters sometimes preceding Ship names.  Make sense? We explain it in this short video.

 This is a video-version of a post from a couple years back.  Feel free to check out the original post here!
