Davy Jones? You plan to make all ghost ships be the Flying Dutchman?
For the sake of the end of this enigma, I'll say DING DING DING we have a winner!
It's not Davy Jones, but you are close enough. It's the original Flying Dutchman's captain, Hendrick van der Decken. To put it simply, he is now a vampire with poltergeist powers. His powers will retroactivelly "insert" him on the story (that's where you wait to see how exactly will it work). However, the ship is not getting renamed. Castlevania named it "Ghost Ship" and Ghost Ship it is.
But remember, he's a minor vampire of Dracula. He will not outshine the big guys, who are still the tried and true Carmilla and Olrox.
