Thanks for all the responses. I asked some of the marine engineering
students at school, concurrently, and they replied more or less the
same thing: way too much trouble. Where you're burning LOTS of fuel on
long runs with a good maintenance schedule and a sizeable crew, it's
worth using bunker. Otherwise, it's way too much of a headache.

Looks like SVO or biodiesel would be a better alternative to straight
diesel.
