Is it the same?

It also depends on what was in the message that the pigeon carried........

The ship changed in physical structure while in transit, but the ship is only a vessel........its contents are what is important.............the people onboard the vessel are the same...............

reminds me of one airplane flight in recent history........

when the airplane took off there was a General who was subordinate to the Prime Minister of a country; was on board............

some hours later when the airplane landed, the General had become the head of the country..........put the Prime Minister behind bars......:)

Be ware of the fast pigeons carrying messages.......:)

coming back to your question..will the ship be the same?

Yes it will have the same shape as the one that started the voyage..........but will not have the same bouyancy!
