What if you replace each piece of the original ship with an identical piece? What if you use all of the removed pieces to build an identical ship? Which one is then the “real” ship?
What if you had a time machine and sent a ship made out of original parts back in time then swapped half of the parts between the two ships?
Will the older pieces immediately rot to dust because the older ship already had those parts swapped out in its past, so the older pieces are actually trapped in a time loop, but since they keep getting older they just disappear, but it’s ok because you have the new pieces from the past so you’re left with a ship with new pieces and slightly older pieces?
