> it doesn't get the boat quicker to a dry dock than towing would for example, But in this case, it did. The ship was located in a part of the world where the available dry dock was currently unable to take it in, so this lift ship is acting as a temporary dry dock to allow the repairs to happen to the ship. So it did "get the boat quicker to a dry dock" because the heavy lift ship is also serving as a "dry dock" while the repairs happen to the cruise liner.
