Re: [Electric Boats] High end electric/diesel yacht

 

On the issue of emissions, the whole point of plug-in hybrid cars is that the energy you get from the electric grid is generated more cleanly per kWh than from an ICE due to more efficiency in a large-scale power plant.  Shouldn't the same hold true for a plug-in hybrid boat?

As for reducing fuel consumption for a short outing. If you're charging the batteries with the generators then you're not saving anything, if you're charging at the dock then you're just displacing the emissions and again, it might be more or it might be less depending on distance to the power generation state, efficiency of the power grid, type of power plant, efficiency of battery chargers, etc. In general, point-source fuel use creates fewer emissions, but like I said, there are so many factors involved it can go either way.
