Re: Electric hybrid Inboard Vs Diesel
Well a 40 amp charger, especially one that likes the charge the gennie puts out, would need to be installed. As would a 48v(or whatever) battery system. And a way to charge both the 48v/12v system on the boat. And battery monitors. And you need to consider the safety of a 2kw gas generator that'll be spewing out exhaust. And then live with the power constants of the system. If it was perfect we'd all be using it.
But I also notice people tend to give petrol systems a pass on a lot of their flaws, because they're used to them. Filtering fuel, polishing fuel, getting "bad" fuel, constant maintenance, holes in your boat for water in/out, zincs to prevent heat exchanger rust, rough seas causing gunk in the tank to free up and jam the fuel system and killing the engine(probably when you need it most), little rubber impellers that fail all the time, water intake clogging up, busted ring seals causing blue smoke out the exhaust, the noise, the smell, crap torque on the low end, no regeneration under sail, you can't lift the engine out by hand, etc etc.
If someone was coming from the electric side and was used to the aux engine range limits, they'd probably think of the idea of re-powering with diesel as laughable.
