Greetings all!
Just to get this out of the way, I've only seen the film, and whatever I find on here. So I am not versed on the books, the websites, JK Rowling's words, etc, beyond what little I have seen for myself. And I was going to ask this via the talk page of the Durmstrang Ship article, but then it may serve better to be asked here. But then I may be mistaken as far as protocol here. Anywho, my question is regarding the Durmstrange ship as depicted in Harry Potter and the Goblet of Fire, book versus the film.
From what I know, the ship can sail underwater and rise from the depths. One may compare it to the Flying Dutchman from Disney Pirates of the Caribbean franchise, beginning with the 2006 sequel film Dead Man's Chest. Though I assume that this idea was already done first by the Durmstrange Ship in the 2005 film, and perhaps the book itself, presuming the description posted in the Wiki article is verbatim from the book.
Please let me know if I'm missing anything here. Also, sorry if the answer is too obvious, and of course if this has been asked and answered before.
