Re: basically it's the plane version of a prius
there are a *lot* of watercraft going this route -- for some values of "efficient" (i.e where we have two straight props for propulsion and say four or six lateral props for positioning/manoeuvring) this is a far more efficient use of diesels. -- one needs two or three diesels turning gennny's charging batteries, the overall ship and powering the props. Most of these are cruise ships, but it is becoming common on large container craft due to sheer size. The diesels run at peak efficiency 100% of the time, and power is available on demand.
