Conceptually, I would not only go with Lithiums and a bulletproof BMS, but on a boat this size I would consider a high voltage ac drive system in order to save on cable weight as well as to easily implement regeneration while motorsailing.
Having cruised for seven years on a production Seawind 1000 10m cat (ICE outboards), I wish you all the best with your massive building project.

I don't plan to use shore power much but should have a 120/240 system which can be connected in the US and outside. I would like to use LiFePo4 batteries, and suspect the price is getting to where they make a lot of sense.

Any related information is welcome. Also any internet sources for background would also be appreciated. Needless to say safe and simple is how I would prefer this project for ease of building and operation!
