1.2 kW-hr on your roof is an excellent spread. Considering your profile of using the boat part time, but being on the hook, your panels will have plenty of time to bring your batteries up full. You can easily support double that battery capacity if you need to expand in the future. Definitely install a PSW inverter for your 240/120 VAC.
It sounds like you have not installed a refrigerator yet, or are open to changing it. Since that is your highest load, purchase an A+++ domestic unit. Also, I'd go with a domestic hot water heater (240V) as well, if you're looking to upgrade, although it would be better to buy a unit designed for solar installations so it can accept an engine loop heater.
Since you're in the PNW, on a given winter overcast day those panels should still generate about 1kW in energy, maybe a bit less. But an efficient refrigerator will use 0.5 kW per day, so you're good to go!
Since you don't have/need air conditioning, there is no need for a generator.
