Walt: Well you're not wrong about the photoshopped photo, and I dunno why they chose that - probably some PR flack thought it looked better.

As for the ship size, well it is a proof of concept, although that IS a working freighter, shipping Airbus parts between factories. We'll have to see how it scales up. The article says they are planning to install one on a 210,000 ton freighter, which would be something to see.
In practice, you'd still have engines for navigating close to coasts and in ports, emergencies, and inclement weather. I also suspect, from this video, that the engines ARE being used, at a low power, probably for rudder authority (I can see what looks like prop wakes).
This would probably only be practical once in the open ocean, with good weather. I can see it being adopted by shipping companies IF the install, maintenance & operating costs are sufficiently low to offset the fuel savings.
