The boat used to consume 100 liters of diesel daily, which is equivalent to 1000 kWh in energy (10 kWh per liter). But after electrification they claim only 150-200 kWh usage per day. This doesn't add up. Were the diesel engines idling all day even when the boat was not moving?
It seems ok to me, EVs have about 13kWh/100km efficiency while an older gasoline car would consume 10l/100km. And yes, it's quite plausible that the engine was running during loading and unloading
You are right. I forgot to account for the fact combustion engines have a terrible thermal efficiency: about 20%, which gives the boat only 2 kWh per liter of diesel, meaning it was using 200 kWh daily, more in line with the electrical version.
