Yup I had my boat moored too for a bit and didn't like it. Was always anxious about weather, mold in the boat, theft, vandalism or any security issues and hated not being by it all the time to be able to do work on it, maintenance, cleaning, tackle maintenance etc..Same with getting ready for trips; had to gather everything up in the truck then lug it to the moored boat and organize it all there then be off. Just didn't like it at all.
My boat is rigged up great for weekend or week long trips. On my trip to Lund I slept two nights on my boat and one in the water front hotel.
I have an invertor/generator wired into my system under one of the bench seats and I also have a gas suitcase 2000 watt genny in case for back up. I have a fridge with small freezer that can run off the inverter/shore power or off 12 volt, fresh water sink, diesel stove, sit down toilet in a separate room, diesel espar heater and my cuddy can sleep 2 adults tightly or two kids easily. I have a few 120 volt outlets in the cabin and lights everywhere. For future trips I'm looking into getting a removable back canvass made for the back fish deck so I can turn that into another closed in sleeping area for my kids when needed. My cabin floor can also sleep one person. I also bought a removable table pole support for the walk way that I can put a table on when needed. I have two air ride seats up at the helm and then two bench seats that seat two people each.
When I'm away from shore power and moored/anchored somewhere and making supper, and using 120 volt power etc just hanging out with the family/friends on the boat, just to be safe I usually fire up my motors just to keep the power to the invertor/generator going in case I draw my batteries down. I have switches on my breaker panel to run off just the 12 volt, shore power, invertor/gen, or both etc.
You should look into how much power can be stored with invertor/generators wired in, and with solar pannels if planning longer off the grid trips. I am looking into that too. I have a friend that keeps a battery bank full of power with solar panels on his sail boat. He has multiple sources of power on the boat. With technology getting better and better the solar panels are getting smaller and more powerful all the time and cheaper. They just had some a few months back at costco for a good price but I wasn't set up yet to buy them.
