I had this idea in mind for quite a long time now and i want to know if anyone already tryed it so they can share their experience.
P.S. My sailboat will be at dock
pretty much all nights with some 2 days trip and very rare 5+ days trip when on vacation
At first, i really like the idea of having an electric engine
as the main prop system since you can power the boat without the noise/vibration of the main engine
running. It's even more usefull for me who wont sail for weeks. ( plug
the boat each nights ).
I will use some solar
power to refill the batteries when not using the engin but i understand that it's practically impossible to have enough solar/wind power to recover the energy that the electrical
engine use plus all the accessories on board. This is why the idea of keeping, maybe a smaller, diesel
engine aboard but using it only as a generator
( more tha one if needed, 12v, 48v, etc ) when needed.
When you are on a trip and you have a full day without wind
and in the need of running on the electric
engine alot, you can simply turn on the engine, idle it at a good RPM
so the alts are able to push enough energy so you dont run out of bat.
Is the idea good ?
