The Streamlined Ocean Liner was a design by Norman Bel Geddes for a streamlined steam-powered ocean liner. The shape was compared by Pathé to that of a porpoise, blunt at the front and tapered at the rear. It first appeared in Geddes' 1932 book Horizons and an outline patent was filed in 1933 with a detailed patent following in 1934. An offer was made for the rights to the design in the late 1930s, which Geddes refused. He still hoped to sell it to an American shipbuilder, but the ship was never built.
