The physics just don’t add up due to the weight, volume and cost of batteries required. Depending how you calculate it, a kilogram of diesel packs 30-100 times the energy of a kg of lithium ion battery.
There’s still a place for hybrid diesel-electric drivetrains that will allow boats to creep silently into port, but the combustion engine is likely to remain the primary source of
