Here's the list of shipping names ported over. The original post only lists characters prefixes but since there are characters that share the same prefix I filled in the suffixes too. Also I included the explanations for the shipping names where I could find them. A lot of them are missing though because I guess they were decided before v4 so we don't have the original discussion anymore.
Additionally there were a lot of threads for ships in the shipping names board on v4 that were not on this list so I assume there was never an official vote for their name. Naming ships is kinda passé now I guess but I made a list of them in case we're interested in giving them names.
