How far is far enough?

I have always wondered how far other boaters get from the dock/ land
before they feel comfortable getting comfortable. Especially here in the PNW we are often not far from land and/or other boats. I would like to hear other peoples ideas of how far from dock, land, other boats you are
before you either disrobe, or cover up as appoaching.
I know for myself it seems to be about 300 yards.
TIA for all responses
