Please help me size my new generator

I need to install a new generator.
The boat will be used for the loop.
The old generator was a Westerbeke 8KW 8BTD.
I have a 1984 Heritage East Nova Sundeck.
I have changed all of the lighting to LED and understand that does not have too much effect on he total needed.
I did add a second 18K btu air conditioner and have studied all of the threads on generators but would like a second opinion as I am unclear on what I should have so I have reserve wattage, but don’t under load the generator.
I also have a Victron multiplus with the spike protection that draws from the batteries for start up spikes if needed. I can’t find a start up amp spec for the air conditioners
Here is what I believe I would have on the hook cooking dinner in the Keys:
2) Dometic 18Kbtu air conditioners at 15.1 amps(15.1x120x2) 3624 Watts
Not sure of the draw for the two water pumps 370 Watts?
Norcold 6 cu/ft AC/DC FRIDGE/freezer .4 amps (.4x 120) 48 Watts
Two burner electric stove top 1200 Watts
Oven 1200 Watts
1200 watt microwave
20 Gal electric water heater 2000 watt
Tv and sound bar
Uline ice maker
If I add up all of the major appliances outside of the TV and Icemaker it totals to
9642 Watts.
I realize they might not all be on at the same time and I should turn some off if using others. I also read that a generator shoul be loaded between 30 and 70%.
If I get a 9KW generator, I could potentially load it to 100%.
Does an 11 KW generator make sense?
Thanks in advance.

Re: Please help me size my new generator

your battery charger is probably another 15+ amps. when your batteries are low. another big load you missed.

Great point. Thanks

It also brings up another point I should have mentioned. I found a great deal on six 100 watt solar panels. I have not been able to install them yet, but working on it over the summer.
