That’s hardly “covered in rust.” As one who has been to sea for a length of time (on an amphib) I could not imagine 215 days on a destroyer. Those things are tiny!
My Dad served on destroyer escorts during WWII on convoy duty in the Atlantic. The ship was so narrow you could hang your hammock across the berth from one side of the ship to another. They rolled so much that hammocks were often the preferred sleeping arrangement. You also didn’t have to worry about a shipmate in the bunk above puking on you.

Not really, you just have 340 roomates
(My Favorite Ship was GK Mackenzie DD836, lots of friends)
