Seems like unless you're close to shore, you really don't need a lot of
engine power. Maybe in a storm, but wouldn't the concern be running the

long?
I'm mean that's why it's a sailboat... to sail.

There are two times when you need power on a sailboat: Bad weather and
good weather.

Most cruising sailboats spend more than 90% of their time underway
with the engine running. Either the wind is from the wrong direction,
too weak or too strong.
Not counting the fact of needing the engine to supply electrical power
to modern refrigeration (if used) and navionics. (Is that a word?)

I don't think this requires a powerful engine... seems like it shouldn't.
Don't people use generators that are separate from the main engine?

Some and probably most do, however like Wayne B has his trawler
outfitted, he uses a high amperage alternator which is powered by his
main engine[s] cabled to a considerable stack of batteries that in
turn power an inverter that converts 12 volt DC current into 120 volt
AC to power his electronics and refrigeration. He says it more cost
effective than running a generator.

Interesting. I've heard about high voltage electric engines for sailboats,
but I have a feeling that might be wildly expensive as a retrofit.
