Well not to be argumentative when we travel in Southeast Alaska there is not too many times that we "Share" an anchorage. If somebody is there when we enter, unless it is a huge bay, we move to the next.
At the rare anchored powerless floats unless it is middle of the visiting boaters from the lower 48 season tied to, running the gen is not a factor because it is just us.
Interesting to note that when say, tying to the dock in Meyers Chuck during the visiting summer fleet or commercial boats is in attendance gen sets are a running so ours is a slight addition to the evening putt-putting. When at a civilized dock where electrical power is available, we willingly hook up.
Making ice or having air conditioning is not a prerequisite. Cold wine-Another story.
Time will tell I guess
