Re: Optimal propulsion system
I've thought about a hybred system leaving the diesel in place then attatching an electric motor to the prop shaft with cog belt, I then could run just diesel, just electric, diesel with electric boost, diesel with recharge,
I would use electric mostly for on/off mooring, docking then diesel for passage making if sailing was not possible. would try to have enough batteries for a few hours.
For my boat I was thinking a 10-12 hp electric DC motor in 48 volts, 8 six volt golf-cart batteries, that should give me 7 hp for an hour.
