Apparently there is this uge differwncw about where you storage them. The only reason some portugues and British ships aren't the oldest sailing vessels is because we keep them in museums. Yhe but they are still in comission, sooo idk I guess we where both right depending how you frase it.
So, while the USS Constitution is the oldest naval vessel still afloat, the HMS Victory holds the record for the oldest naval vessel still in commission. Both ships are significant historical artifacts and serve as museum ships, commemorating important eras in naval history.
Victory would sink if put on the sea.
Over time, repairs have been carried out to maintain her appearance, but not her seaworthyness. In many places, soft wood has replaced hardwood and no effort has been made to ensure she is structurally sound or water tight.
Victory would likely sink in the dry dock before the tug could take her anywhere. There has been no effort made to make her float. Hull repairs done over the last few decades have not been made water tight.
It wouldn't constitution had never been dry docked as a matter of long term storage, victory hasn't seen water in a hundred years (April 8 1925) and no you cannot easily just drop her back in the water and expect her to float. That said constitution could sail today if it were advantageous to do so, last time she sailed in her own power was July 21 1997.
