Hi Sergio-
I had a Pearson 35 sloop which I converted to electric power some time ago, sold the boat a few years back. The conversion used an electric yacht motor, 5 KW, running at 48V. The range you get will depend on the amp hours in the battery pack. Mine was 48V, 220 amp hours lead acid batteries. I could get up to 5 knots if the hull was clean, could run at 4 knots for a couple hours. The slower you go the longer your range also. I always recharged at the dock. It took 12 hours or more for my charger system to fully charge the batteries, but that was fine for me because it was used mostly as a day sailor.
Many folks take a 2 KW generator along for overnight trips or cruising, I didn't find it necessary for day sailing. Solar panels can help, but you would need a lot of them to make much difference while sailing.
Keeping the hull clean makes a big difference, for both electric motor and sailing performance.
I really liked the electric motor vs the diesel. A lot less maintenance. totally quiet. No diesel smell. Your 12 KW system should take your boat up pretty close to hull speed, but back off on the throttle if you are going to run under motor for any length of time.
Enjoy!
Bob

I just bought a Pearson 35 yawl..and has an electric motor from thunderstruck motors..it is a 12 .5 kw running at 72 volts battery bank. I haven't said it yet. But I can wait for this coming weekend..I'm bringing on board a 2000 watts generator since don't know what is the autonomy I'm going to have...thinking if it is possible some sore of solar system I can Install so some have I put back some amps while sailing..
