The problem is confusion between being dockside with essentially unlimited power supply and away from the electric umbilical cord. It's nice to have everything at the dock--I've got the microwave, the LCD TV, the DVD player, the sound system, the blender, the watermaker, the hair dryer, the coffee maker, the oversized laptop.....
But you really shouldn't try to recreate dockside power when away with the assumption you can use everything like at the dock. Even with a generator, huge battery bank, 2500 watt inverter/charger, and a wind generator there is a need for an electrical budget. I used to not have an electrical budget because I had a nuclear fuel rod assembly embedded in my keel--but I had to get rid of it because the boat glowed in the dark.
Seriously, there's nothing wrong with having things on your boat that provide enjoyment. Just be realistic with your energy requirements and ability to supply energy away from the dock.
