I'm out on my paddle board in marinas and anchorages around San Diego and Coronado. I see a lot of wind generators as well.
Like Npr suggests, but with a wind generator as well. One is none, 2 is one... Belt, suspenders, rope, duct tape.

Yeah the channel I mentioned (Delos) has a couple of wind generators, along with a permanently mounted diesel generator and lots of solar. With a big enough boat you've got the space to have plenty of options for power. A few years ago when they were crossing the Indian ocean they even dragged a towed generator due to some problem with another part of their charging system. From what I remember, they usually only run the genset when they need enough power to operate their dive compressor or water maker.

TMK, most of the serious yachts these days, have Z pods. Lets them have one engine, and a large generator, and still have the redundancy of 2 engines. Significantly reduces their fuel usage. Z pods, of course also greatly improve the maneuverability.
I see some sailing yachts with the same set up.

Some of the ships in the story I’m writing are Diesel-electric, with multiple generators and motors, but at a mid-1930s tech level. I’m thinking about having them use lead-acid batteries as part of their ballast, for emergency power.

You're probably not going to see anything like that on the size or price range of boats that I am talking about though. Bow thrusters on some of the larger ones, but that's about it.

Factbox: Electric-vehicle batteries: major players and their expansion plans
SEOUL, Oct 22 (Reuters) - The global auto industry's shift to electric vehicles (EVs) has spurred an expansion race among battery makers and led to a growing skills shortage. read more
Global EV sales, estimated at 2.5 million vehicles in 2020, is forecast to grow more than 12-fold to 31.1 million by 2030 and account for nearly a third of new vehicle sales, according to consulting firm Deloitte.
Here are major players' expansion plans in key EV markets of China, the United States and Europe.

Basically anything bigger than 50 feet, with the exception of gofast boats, is at least offering a pod option ..
They make maneuvering big boats vastly easier, especially combined with bow thrusters. What they did don't tell you is they cost vastly more than a traditional inboard setup, both to install, and to repair. They also need deeper water as the pod hangs much farther down than an inboard prop.
