@neauoire When I was on a mooring down in the BVI's, we'd run our generator at night, because damned if I was going to sweat through a night with small children aboard.
We shut it all down when everyone got up for breakfast, but I did feel a slight twinge of guilt through the night. It didnt' last long. I sleep hard.
@RoyGreenhilt here it's illegal to run generators after sunset at least.
