I have a generator and I am not afraid to use it!!!
You don't mention the size of your boat. It must be a "Big un". Maybe I didn't understand the post, but whats wrong with running the genny?

If you're staying with lead-acid (flooded or AGM) batteries and don't care about getting the fastest recharge possible from the alternators, you can just add ACRs and skip the external regulators. You won't cook the batteries and they'll still power your loads fine.
That 'anyone else' is a bit broad, no?A decent battery bank and a decent inverter seems the obvious solution to me and anyone else who runs a boat on 240/110v power.

I'm skeptical on how long an Ocean 53 is going to keep going running everything from the 12v system. It's not going to be business as usual.
I'm no fan of gensets, but for the OP a second genset could provide unlimited full failover. Getting similar from alternators/ batteries and inverter is going to be more expensive and/or come with a bunch of limitations.

I smoked two large frame alternators trying exactly that charging AGM.
Good point, depending on the size of the battery bank and the alternator in question, dumping full output with just the internal regulation may lead to a cooked alternator.
Interestingly, I've found my stock 55A small frame alternators seem to de-rate themselves sufficiently as they warm up to avoid cooking when asking for full output for hours on end (which was a pleasant surprise).
What is the SOC of your house bank when that occurs. wondering if the ALT is allowed to operate under internal reg parameters as there is less demand. As in a certain voltage is reached.
Your house bank is not oversized for your ALTs working together so they perform as intended. What size is your house bank Ah.
you start off with 65A into batteries, was/is there a load on top of this. an example if each battery puts out 40A, total 80A then 15A is being consumed.
You have a balanced system
