It's striking for sure, but now I think about it I'm not sure exactly what it 'means' either. Water having ebbed away and left it sitting there, but of course there was no water in the first place. It's almost like wishful thinking, haha.

I think originally my mind went to climate change, but technically it would lift the boat in that case, not leave it stranded... A future evaporating away? There's so many places it could go really! (not literally) :)

Well water is life... abandoned boat means no life... natural order upset, humanity marooned (or wiped out). Apocalypse, now. Not, exactly “energetic with optimism” :)
