I think pure electric is most common for sailboats. Where can get most of your propulsion from the wind and power from solar. My understanding is that range on electric is small. Fine for harbors but not enough if wind is wrong. It is usually possible to drift but that wastes time and can be problem in some situations. Most electric drive sailboats have a diesel generator as backup.
