It's definitely a "land-lubber's" song -- a bunch of nautical-sounding phrases strung together that don't really make sense if you think about them too hard. But that's fitting for a Hollywood fantasy with a pirate aesthetic.

But performed well, it has an effective vibe, even if no-one would confuse it with a real Fo'c'stle shanty.

And this is performed well. I liked how the singers traded off the lead in the middle of lines, and did it seamlessly. And I'm a sucker for polyphonic harmonies.
