Generator etiquette.
I agree that a motor running in a silent anchorage, when all are relaxing and trying to take in the solitude is bad form.
However, I think many take this notion to an extreme and wouldn't like to hear a generator at any time. I do not think you have to try to make everyone happy. You are allowed to play music in your apartment during the day, despite whether others can hear it. You should respect the evening hours. Same principal applies.
Here's an anecdote. On our trip this past June to Maine, we were anchored in Seal Bay and were absolutely alone until about 9pm, when another boat arrived. This is probably one of the most secluded, quiet, peaceful places I've been on earth.
When we woke the next morning, we were freezing. Temps around 50, overcast, drizzle and 100% humidity. We threw on sweatshirts, hats, etc and just couldn't get warm, because they were all slightly damp. We suffered for an hour, because we didn't want to start the generator to run the heat
pump to warm up the boat and disturb our neighbor.
After we thought we couldn't stand the cold any longer, we were looking over to see if our neighbors were at least awake and I noticed some ripples around their transom. I pulled out the
binoculars and they were already running their generator!!!!! We couldn't even hear it.
