Re: generator a good idea?

Even if you don't know your exact power consumption you do need to at least list out the major consumers of power. If you have even a half decent battery and no fridge you should be able to live at anchor for many days without solar.

The first step is a battery monitor to understand how much juice is left after a day's worth of cruising.

You don't need much solar if you don't have a fridge, just a little bit goes a long way. Our boat has a 30 watt panel (2.5 amps at 12 volts) and more than covers our needs for summer cruising. If I were buying today I'd probably buy a 50-60w panel just for a bit more overhead. I don't plug in the boat for about 6 months of the year, even at my home dock.
