Ted nailed it. We have those on our Sea Ray. Is the boat an ocean crosser? Nope, it's a coastal cruiser and those doors are great.
I can't speak to those doors in the photo, but a couple of years ago I had the rollers replaced at the bottom of our doors. It took two guys to lift them out of the track they ride in. They are definitely not your run of the mill, lightweight home patio door.
