Hi all. I am looking for a long-range trawler and notice that many

just one
engine.

The problem would be to balance the two engines. Which is why you
typically see either 1 shaft per engine or one generator per engine and
a electric motor driving the screw.

Y drives are available, some large motor yachts use them.
They allow you to run on 1 engine for economy cruise and both
when you want to go faster and burn plenty of fuel.

The added advantage is a shorter engine room because the engines
are mounted at 90 degrees to the centreline.
