Built to ship intermodal containers — those corrugated metal boxes that hold anything and can fit on ships, trains and trucks — from China to Europe, the Marco Polo is the largest vessel of its kind, measuring in at just under 1,300-feet long, and the first of three similarly sized ships ordered by French shipping line CMA CGM.

Its capable of holding 16,000 containers, a measurement that’s called twenty-foot equivalent units (TEU) in the shipping industry. That means 2.1 million refrigerators or 13.4 million 42″ televisions. If the Marco Polo were an apartment building, it would have about 2,300 one-bedroom units.
