Lionel 6801-50 Yellow Boat - The Lionel 6801 series of boats first appeared both on flatcars as well as in separate sale boxes in 1957. Production continued through 1960. There are 3 known colors of boats, brown deck with white hull, white deck with yellow hull and white deck with blue hull. There is supposedly a rare variation of the blue hull boat that is teal in color, however no known mint original of this variation have been found. The teal version is thought to be nothing more than fading of the blue color.
