Okay, during another show, GD sings, "we were a hospital ship, I'm really glad you lost," which matches neither incident.

I've seen him say a lot of contradictory things about songs, so I think we need to take those statements with a grain of salt. There's a tendency to try to obscure the specifics and the meanings; no point in writing a song and then turning around to say, "this is what it's about."

What makes Nautical good as a lyric is that it's capable of differing interpretations. Personally, although the Lancastria details are the best fit I've found yet, I don't think there's any real need to link the song to any specific sinking at all.
