Tom, there are several projects completed and many underway in approximately your size range. 48 volt systems seem to be the normal voltage for most but some run on 36 volts. Look through the photo section, you'll find several to draw ideas from. There are several guys one the site that are building a business out of electric conversions making kits/pods and other things that may be of interest to you. My boat is a 30 ft ChrisCraft Capri sailboat that weighs in at 12000 lbs. I use a Etek brushed motor 8 hp and have the same bollard pull as a friend of mine on his 50 hp diesel, (a little over 300lbs), so you see it's not just rated Hp that does the job, it's also efficiency..

Hello everyone!
I know there must be a thread for powering sailboats over 30' with electric motors. Can someone direct me to it?
My sailboat is a Cal 35 Cruising. She is of 15,000 lbs. Displacement.
I think this project would need around 35 hp. She has a 4-108 Perkins of 'Claimed' 50HP hahahaha!
Anyway, with what little I know about this, I would need a bank of about 5 Golf Cart Batteries.
I also want to utilize Solar Panels as well as a Gas Power Generator.
So let me know how screwed up my ideas are so I can get an idea of where to start here.
Thanks
