I have 2 generators I rarely use. In the past one ran when ever cruising or anchored.
But I put in a good inverter, dedicated battery bank, and extra alternators on the mains. Now I only use the generator at anchor and then only every 2-3 days. The mains keep the bank charged when cruising. So when I anchor, the bank is topped off. I have a big reefer, 2 freezers, induction cooking, incinerating toilets, tv, starlink, etc.
I live aboard, but if I was a weekend cruiser, I wouldn't need a generator.
