The first Good Ship Stubborn
The Good Ship Stubborn is the second cruise ship Mr. Stubborn owned, and it's identical to the S.S. Stubborn. Like with the former, the Good Ship sank due to icebergs, even though he thought they are harmless. Everyone on board except for the Captain himself escaped the ship.
It only appeared in Ships.
The second Good Ship Stubborn
This ship was already sunken due to a previous event that Mr. Stubborn caused about a year ago. The discovery team tried to retrieve it, but because Mr. Stubborn refused to believe and was furious, he caused Miss Daredevil's submarine to leak, and have to escape. The ship was later rescued at the end.
It appeared only in Out To Sea.
- It's unknown if this ship is the same one that sank in Ships. It could be the same, as Miss Chatterbox was there when it sank. However, it is depicted smaller than how it was in Ships, and they never explained if it sank from icebergs.
