What are your expected sailing conditions (winds, tides, chop, etc). It has a lot to do with how you size the system.
Based on my experience (Hunter 30 9800lb disp) I would go with one of those dual-motor/dual-
Someone just posted on one for sale but I think the numbers (9KW @ 24V) were wonky - that's probably the 48 or 72V max HP rating.
9KW is about 12HP - should handle most conditions just fine on your boat as long as the batteries hold out. That's the real problem on larger boats - your "diesel credit" in weight isn't much better than mine, but you need more power, so you're either going to be heavy or have less range.
