I really don't have much I coulr relate to you in just 1000 character bites. But go full parallel hybrid is my advice. Diesel and tranny coupled to each shaft, Electric motor belt and pulley coupled to each shaft. Totally independant but cross connectible system in each hull complete with bank. Go FLA not lithium. Forget about wind generator. Don't count much on regen. Forget about AC and dishwasher and other electric frippery unless you plan on running a generator most of the time. Stay with 48v under 36 feet, over that consider going with a 200 to 400v system. Consult with experts. Do your homework. Thats all I got for you. Hope this is finally short enough

part - 2

currently looking at a 48v propulsion system with a 48v generator to use as a backup and a large Li bank X 2 (catamaran) along with solar and wind (both high and low wind generators) use propulsion for regeneration as well and want most of the modern stuff, water maker, washing machine... Currently has 2 refers, 1 freezer, 3 electric winches, A pilot, windless, 5 AC units, ect - its your typical charter boat layout. Will be planning as much of the work myself with a ABC certifier to assist with not dying. Man, is this just completely impractical? I've dreamed of a hybrid system since I started sailing - any help would be appreciated,
Thanks-J

Hello,
read that you possibly have a 48v propulsion system?
I am new to the world of cruising though have sailed for years in many oceans, mostly Caribbean on charter and will be retiring to a Lagoon 440 I got for a steal (we'll see when I actually live on it!)
I have been working with a couple electric propulsion companies and have a decent budget to go hybrid. What I seem to be running in to is the issue with 48v. Reading many or your posts it seems that both a 48v and a 12v bank is the way to go.
Q: if you had this platform and all tech we have available today, how would you do this?

told it was too long so I'll go with two parts - part 1
