If you access Yachtworld and search for listing #61889-1563030 you
will find a 36-foot Grand Banks Classic. This single engine GB has an
engine rated at 210-HP.

Overpowered, go-fast boat!.

Mrs. E's. 36 GB Classic is powered by a single, 120 hp diesel.

Eisboch

And had the original owner opted for twins instead, you'd see a pair
of 120 HP diesels in there, not a pair of 60's or 75's.

Aside from the ****-slinging about size of twins, I've noticed while
reading the journal of a sailing cat circumnavigating that he normally
powers on one engine, alternating which is being used to keep the
hours on them about the same. This cat has twin diesels and a 25'
beam, so I suppose the rudder torque isn't an issue. For docking both
screws are used.
Would a trawler with twins normally power using both engines?
Taking the question of twins out of the realm of speed and into
a fuel miserly usage puts a different light on twins.
What's your experience with twins in a trawler?

Long range passage makers routinely run only one engine in a twin
screw trawler.
In my experience, observation, and conversations most local cruisers
just out for a weekend run won't bother to do so.

Some transmissions are more forgiving of "freewheeling" than others,
while in other cases it's necessary to physically brake the idle shaft
to prevent transmission damage.

Chuck apparently knows quite a bit about freewheeling trannies...
