true I suppose but it is very apparent that many have been well maintain above the water line and show a lot of wear and tear below. That applies to even the well maintained ones. The primary exceptions being the cruise lines of coursei said higher end merchant ships, the various fleets run the gambit that goes from death trap to Starship. merchants try to avoid storms, but they have routes and timetables they must meet. They spend a lot of time at sea. I would agree that they are not as particular as we are in regards to the environment.
